摘要研究了基于RTDS的微电网运行和综合监控系统数模混合仿真实验平台，主要包括RTDS实时数字仿真系统、分布式电源控制系统和微电网运行与综合监控系统（EMS/SCADA）三部分。RTDS实时数字仿真系统对微电网中的网络结构、各分布式电源和负荷的主回路电气部分和相应控制系统进行实时数字仿真模拟，并通过相应模拟量和数字量的输入输出接口与外部分布式电源控制系统和微电网综合监控系统进行实时数据交互，实现软件和硬件结合的闭环仿真。最后基于该方法，搭建了针对风柴储独立微电网系统的数模混合仿真实验平台，可对微电网协调控制策略和能量管理策略等关键技术进行有效验证。

（Key Laboratory of Smart Grid of Ministry of Education Tianjin University Tianjin 300072 China）Abstract The configuration of a digital-analog hybrid simulation experimental platform for the operation and control testing of a microgrid, based on real-time digital simulator (RTDS), a real control system for the distributed generators(DGs) and the integrated operation, monitoring and control system(EMS/SCADA) of a microgrid, has been discussed. The RTDS system is for the network structure and power circuit model simulation of distributed generators and loads in the microgrid, as well the related control system simulation. With the data exchange between RTDS, the real control system for the distributed generators and EMS/SCADA achieved by the RTDS analog/digital I/O interfaces, a hardware-in-the-loop simulation system can be realized. Finally a specific experimental platform for the operation testing of a wind-diesel-battery storage microgrid worked in stand-alone mode is set up, where the coordinated control strategies and energy management algorithms for the microgrid is indicafeal.
