TC.ACS.50.528.4WR.HC.LC Programmable Bidirectional AC Power Source
Features Scope of Application The increasing number of alternative power sources like solar, wind driven or biological energy systems call for consistent and well demanding regulations for energy feed into the utility grid. Manufacturers of such systems have to test and to prove the compliance of their equipment. REGATRON TC.ACS represents the newest generation of fully programmable, full 4-quadrant grid simulation systems. Modular architecture and additional operation modes make them an ideal choice for test and R+D laboratories. TC.ACS - Programmable Parameters Each phase individually programmable Variation of fundamental frequencies up to 1000 Hz Variation of phase angles Variation of amplitudes Step changes of fundamental frequency Voltage drops either three phase or each single phase Asymmetric three phase voltages Micro-ruptures and flicker Periodic and single shot under- and over-voltages Superimposed harmonic and inter-harmonic voltages up to 5 kHz Specialized software for EMC characterization The Grid Simulation System as a Building Block of a Complete Test Environment Owing to the full 4-quadrant capability of the TC.ACS system, almost all AC power equipment can be tested with the appropriate test procedures. An integrated test environment for solar inverters is composed of a Solar Array Simulation block (SAS), the device under test (DUT) and the grid simulator system (ACS). While the REGATRON SAS components allow for precise simulation of a user-defined solar array of any order under arbitrary conditions, the ACS simultaneously defines the different test conditions with respect to the grid connection. Depending on the requirements, the ACS functionality may be tailored with various software options. In addition to the Basic Waveform Generator Mode and the Amplifier Mode, which are within the standard scope of delivery, the options Full Waveform Generator Mode with Fourier Synthesis Tool, Current controlled Amplifier Mode and Load Simulation Mode are available. Software An intuitive application based software with various options allows for manual operation, programming and for automated test runs. With the optional Full Waveform Generator Mode (GridSim) a set of predefined voltage shapes – sine, cut sine, square, triangle, sawtooth, user defined - facilitates a quick and easy definition of specific grid situations. This software option also offers freely programmable modulations on each phase for amplitude, frequency and phase angle. Hardware REGATRON grid simulator systems use a state of the art multilevel double inverter technology. The main advantages over existing linear power supplies are a substantial reduction of power losses, full 4-quadrant operation, very compact power units and the modular, cost-effective architecture. This allows the user to choose a system size well-fitting his requirements, including the possibility for future power expansions and/or splitting-up of the system into several stand-alone subsystems. The basic triphase power units of 30 kVA or 50 kVA may be expanded by simply paralleling further blocks even to big systems reaching 2000+ kVA.

Using NVWMI to monitor GPU performance (16)Figure 1 NVIDIA vGPU Software server interfaces for GPU management (2)T able 1 Summary of NVIDIA vGPU Software server interfaces for GPU management (2)The NVIDIA vGPU software Management SDK enables third party applications to monitor and control NVIDIA physical GPUs and virtual GPUs that are running on virtualization hosts. The NVIDIA vGPU software Management SDK supports control and monitoring of GPUs from both the hypervisor host system and from within guest VMs.NVIDIA vGPU software enables multiple virtual machines (VMs) to have simultaneous, direct access to a single physical GPU, using the same NVIDIA graphics drivers that are deployed on non-virtualized operating systems. For an introduction to NVIDIA vGPU software, see Virtual GPU Software User Guide.1.1. NVIDIA vGPU Software Management InterfacesThe local management interfaces that are supported within an NVIDIA vGPU software server are shown in Figure 1.Figure 1 NVIDIA vGPU Software server interfaces for GPU management For a summary of the NVIDIA vGPU software server interfaces for GPU management, including the hypervisors and guest operating systems that support each interface, and notes about how each interface can be used, see Table 1.T able 1 Summary of NVIDIA vGPU Software server interfaces for GPUmanagement1.2. Introduction to NVMLNVIDIA Management Library (NVML) is a C-based API for monitoring and managing various states of NVIDIA GPU devices. NVML is delivered in the NVIDIA vGPU software Management SDK and as a runtime version:‣The NVIDIA vGPU software Management SDK is distributed as separate archives for Windows and Linux.The SDK provides the NVML headers and stub libraries that are required to build third-party NVML applications. It also includes a sample application.‣The runtime version of NVML is distributed with the NVIDIA vGPU software host driver.Each new version of NVML is backwards compatible, so that applications written to a version of the NVML can expect to run unchanged on future releases of the NVIDIA vGPU software drivers and NVML library.For details about the NVML API, see:‣NVML API Reference Manual‣NVML man pages1.3. NVIDIA vGPU Software Management SDK contentsThe SDK consists of the NVML developer package and is distributed as separate archives for Windows and Linux:‣Windows: grid_nvml_sdk_412.47.zip ZIP archive‣Linux: grid_nvml_sdk_410.141.tgz GZIP-compressed tar archiveThe contents of these archives are summarized in the following table.NVIDIA vGPU software supports monitoring and control of physical GPUs and virtual GPUs that are running on virtualization hosts. NVML includes functions that are specific to managing vGPUs on NVIDIA vGPU software virtualization hosts. These functions are defined in the nvml_grid.h header file.NVIDIA vGPU software does not support the management of pass-through GPUs from ahypervisor. NVIDIA vGPU software supports the management of pass-through GPUs only from within the guest VM that is using them.2.1. Determining whether a GPU supports hosting of vGPUsIf called on platforms or GPUs that do not support NVIDIA vGPU, functions that are specific to managing vGPUs return one of the following errors:‣NVML_ERROR_NOT_SUPPORTED‣NVML_ERROR_INVALID_ARGUMENTTo determine whether a GPU supports hosting of vGPUs, call the nvmlDeviceGetVirtualizationMode() function.A vGPU-capable device reports its virtualization mode asNVML_GPU_VIRTUALIZATION_MODE_HOST_VGPU.Managing vGPUs from a hypervisor by using NVML2.2. Discovering the vGPU capabilities of a physical GPUTo discover the vGPU capabilities of a physical GPU, call the functions in the following table.2.3. Getting the properties of a vGPU typeTo get the properties of a vGPU type, call the functions in the following table.2.4. Getting the properties of a vGPU instance To get the properties of a vGPU instance, call the functions in the following table.2.5. Building an NVML-enabled application for a vGPU hostFuctions that are specific to vGPUs are defined in the header file nvml_grid.h. To build an NVML-enabled application for a vGPU host, ensure that you include nvml_grid.h in addition to nvml.h:#include <nvml.h>#include <nvml_grid.h>For more information, refer to the sample code that is included in the SDK.NVIDIA vGPU software supports monitoring and control within a guest VM of vGPUs or pass-through GPUs that are assigned to the VM. The scope of management interfaces and tools used within a guest VM is limited to the guest VM within which they are used. They cannot monitor any other GPUs in the virtualization platform.For monitoring from a guest VM, certain properties do not apply to vGPUs. The values that the NVIDIA vGPU software management interfaces report for these properties indicate that the properties do not apply to a vGPU.3.1. NVIDIA vGPU Software Server Interfaces for GPU Management from a Guest VMThe NVIDIA vGPU software server interfaces that are available for GPU management from a guest VM depend on the guest operating system that is running in the VM.3.2. How GPU engine usage is reportedUsage of GPU engines is reported for vGPUs as a percentage of the vGPU’s maximum possible capacity on each engine. The GPU engines are as follows:‣Graphics/SM‣Memory controller‣Video encoder‣Video decoderThe amount of a physical engine's capacity that a vGPU is permitted to occupy depends on the scheduler under which the GPU is operating:‣NVIDIA vGPUs operating under the Best Effort Scheduler and the Equal Share Scheduler are permitted to occupy the full capacity of each physical engine if no other vGPUs are contending for the same engine. Therefore, if a vGPU occupies 20% of the entire graphics engine in a particular sampling period, its graphics usage as reported inside the VM is 20%.‣NVIDIA vGPUs operating under the Equal Share Scheduler can occupy no more than their allocated share of the graphics engine. Therefore, if a vGPU has a fixed allocation of 25% of the graphics engine, and it occupies 25% of the engine in aparticular sampling period, its graphics usage as reported inside the VM is 100%. 3.3. Using NVML to manage vGPUsNVIDIA vGPU software supports monitoring and control within a guest VM by using NVML.3.3.1. Determining whether a GPU is a vGPU or pass-through GPUNVIDIA vGPUs are presented in guest VM management interfaces in the same fashion as pass-through GPUs.To determine whether a GPU device in a guest VM is a vGPU or a pass-through GPU, call the NVML function nvmlDeviceGetVirtualizationMode().A GPU reports its virtualization mode as follows:‣ A GPU operating in pass-through mode reports its virtualization mode as NVML_GPU_VIRTUALIZATION_MODE_PASSTHROUGH.‣ A vGPU reports its virtualization mode asNVML_GPU_VIRTUALIZATION_MODE_VGPU.3.3.2. Physical GPU properties that do not apply to a vGPUProperties and metrics other than GPU engine usage are reported for a vGPU in a similar way to how the same properties and metrics are reported for a physical GPU. However, some properties do not apply to vGPUs. The NVML device query functions for getting these properties return a value that indicates that the properties do not applyto a vGPU. For details of NVML device query functions, see Device Queries in NVML API Reference Manual .3.3.2.1. GPU identification properties that do not apply to a vGPU3.3.2.2.

The laser source in the Source Optics Module (SWS20010) is Class 1. The Tunable Laser Source (SWS17101) is a Class 3B laser. Boththe module and laser source are classified per IEC standard 60825-1(2002) and comply with 21CFR1040.10, except for deviations per Laser Notice No. 50, July 2001.Data SheetVIAVIMAP Swept Wavelength System (mSWS)The new MAP-based Swept Wavelength System (mSWS-A2) is the next generation of an industry standard. More than 100 manufacturers around the world rely on the SWS to measure insertion loss (IL), polarization dependent loss (PDL), return loss (RL), and directivity as a function of wavelength in both research and development (R&D) and production environments. The new mSWS-A2 raises the bar on test speed, accuracy, and resolution, all while maintaining its patented distributed architecture todeliver the lowest-cost testing in the industry.With a dynamic range of >70 dB, the mSWS provides industry-leading performance combined with low costof ownership. The patented distributed architecture supports up to eight separate, individually-controlled measurement stations per source laser. Often purchased initially as an R&D tool, its measurement station scalability lets customers flexibly transition the equipment from R&D to production.Figure 1. Example of ultra-high resolution where all data was collected at 100 nm/s sweep speedInstalled SWS2000 systems can be upgraded by adding new mSWS-A2-based measurement stations to maximize the benefit to existing SWS users within their existing capital infrastructure.The SWS directly measures IL, PDL, and insertion loss as a function of wavelength and measures RL with the optional RL modules.Figure 2.

Improved software with easy-to-use analysis toolsThe set of mSWS-A2 data link layers (DLLs) can be used to develop software for custom testing requirements. The DLLs function through the mSWS receiver hardware, allowing access to all SWS functionality. Using the supplied DLLs, users can develop applications in Visual Basic™, C, C++, or LabView environments.With a 4-state polarization controller located within the SOM, PDL and average loss can be measured quickly as a function of wavelength. It can measure four polarization states at 0°, 90°, –45°, and circular polarization and uses the Mueller matrix analysis to accurately determine PDL at all wavelengths scanned.Integrating the mSWS functions into the MAP-300 platform lets users access the full power of the MAP-300 application modules. T est systems can be automated with additional switches and laser sources. Fitting the MAP-300 with various connector inspection tools keeps dirty connectors from corrupting measurement results.SpecificationsParameter SpecificationWavelengthRange1520.086 to 1630 nmAccuracy±2 pm absoluteResolution User selectable at 3, 1.5, 0.75, or 0.4 pmMeasurement Time (all channels are measured in parallel)SOM sweep rates10, 20, 40, and 100 nm/sSweep periods (s)1C band time10 nm/s 820 nm/s 5.540 nm/s 4100 nm/s 3C L band time10 nm/s 1520 nm/s 940 nm/s 6100 nm/s 4Insertion LossMeasurement range2Stand-alone station70 dBDistributed station60 dBNoise4 at 10 nm/sweep rate0 to –20 dB< ±0.005 dB–20 to –40 dB< ±0.02 dB–40 to –50 dB< ±0.05 dB–50 to –60 dB< ±0.2 dBBase uncertainty3±0.03 dBResolution0.001 dBMaximum slope tracking at 10 nm/s0 to –60 dB IL>0.4 dB/pmParameter SpecificationReturn LossMeasurement range560 dBNoise4 at 10 nm/s0 to –20 dB< ±0.02 dB–20 to –40 dB< ±0.06 dB–40 to –50 dB< ±0.2 dB–50 to –60 dB< ±0.5 dBPDLMeasurement range650 dBNoise4 at 10 nm/s0 to –20 dB< ±0.01 dB–20 to –40 dB< ±0.04 dB–40 to –50 dB< ±0.1 dBResolution0.001 dB1.

Abstract This paper presents a concept about Software Defined Grid (SDG) to solve the problem in existing grid. On the basis, this paper has identified the designed goal, described the architecture and analyzed the application scenarios of SDG.
1. Introduction In the past 50 years, the automation level of the power grid has made great progress [1]. However, it exists huge gaps between the existing grid and the smart grid imagined in the future [2] [3]. Existing grid cannot deal well with such problem, like active distribution, distributed energy, energy Internet and etc. [4-12]
SDG splits the control plane and data plane of the computer network facilities, using the centralized control of logic to establish programmable network architecture, and thus to support the innovation of different kinds of new business. By invoking the concept and methodology of software-defined, the traditional and rigid power grid turns to be logical and flexible. And then, the grid system can own stronger adaptability and flexibility to cope with the issue of the power network communication system and the grid security. What's more, by the Separation of management, control and operation, SDG can greatly increase the possibility about the access of distributed energy and the support of new functions and new business [13] [14]. At the same time, the power grid will obtain the
ability of energy interconnection with the techniques provided by SDG.
2. The concept of SDG The concept of Software-Defined was proposed and applied in computer network, namely the software defined network (SDN) which people are familiar with. There are three features in SDN, the separation of control and forwarding, open programming interface and centralized control. SDN successfully changes the
architecture, control and management in traditional computer network. The core idea is to achieve the separation of all or parts of the architecture, control and management. Both the software and the hardware of the traditional grid system are coupling. The operation, control and management are interconnected, composing an indivisible whole. When constructing new functions or new businesses, all the systems need to be redesigned, re-achieved and re-deployed. Such a coupling operation model has greatly hindered the development of the power grid. SDG, in fact, bases on the traditional power grid, using the concepts and methods of software-defined to achieve the separation of the architecture, control and management of the traditional grid. In this way, the structure and operation mode of the power grid will be more flexible.
3. Architecture of Software Defined Grid Figure 1 is the layered structure diagram for SDG. From bottom to top, SDG includes three layers, the Running Layer (RL), the Controller Layer (CL) and the Application Layer (AL) and it also includes two interfaces, the South-Bridge Interface (SBI) between CL and RL, the North-Bridge Interface (NBI) between CL and AL.
3.1. The layers of SDG Running Layer. The running layer includes the power grid devices and the communication devices, located at the bottom of the SDG. It receives instructions from the control layer, completes the control operations and reports the status of the running layer to the control layer. Controlling Layer. The controller layer includes the Grid Operating System (GOS) and generalized power grid state data. GOS is the core and backbone of the whole SDG. It collects generalized power gird state data, decomposes the applications of upper level customization and distributes control commands to the devices of the running layer. Application Layer. The application layer includes a variety of applications serving the functions and businesses of the power grid. With the interface access
Software Defined Grid Xu Ranci Fudan University 14210240055@fudan.edu.cn controllers, the applications can not only access and control intelligent devices but also access the generalized power grid state data of the controlling layer. Thanks to this layered architecture, it’s very convenient for SGD to use the "soft method" to develop new applications and new businesses. 3.2. The interfaces of SDG SDG includes two different interfaces, South-Bridge Interface and North-Bridge Interface, located at different layers. South-Bridge Interface is located between controlling layer and running layer as an interactive channel. It is a low level interface protocol, completing the two-way communications of information between two layers. Because of the different types of the devices, NBI should also be implemented in a variety of ways. North-Bridge Interface is located between controlling layer and application layer as an interactive channel as well. It is a high level interface protocol. With the increasing of businesses and applications, the functions of interface will increase and the forms of interface will become diversified at the same time.
