Quality Control Testing Of New Technologies To Analyse Energy

Electric quality control testing of new technology analysis summary : With advances in technology,

modern power system electricity load structure has undergone major changes, such as the semiconductor

rectifier, transistor rubber and frequency conversion adjustment devices, steel-making furnaces, electric

railways and household appliances such as load rapid development, because of its nonlinear, and the

uneven impact of the electricity identity the grid voltage waveform distortions occur as a flash change and

the three-phase voltage fluctuations and imbalances, or even cause system frequency fluctuations, the

quality of electricity supply to cause serious interference or "pollution" . In the face of increasing

electricity grid CKS quality issues, which makes electric quality research is extremely pressing. Electric

quality testing is the most direct access to relevant data conversion means, but also the quality of other

follow-up High energy applied research front.

1 electric quality research, the application of new technologies background

With advances in technology, modern power system electricity load structure has undergone major

changes, such as the semiconductor rectifier, transistor rubber and frequency conversion adjustment

devices, steel-making furnaces, and household appliances, such as railway electrification load rapid

development, because of its nonlinear, and the uneven impact of the electricity identity the grid voltage

waveform distortions occur as a flash change and the three-phase voltage fluctuations and imbalances, or

even cause system frequency fluctuations, the quality of electricity supply to cause serious interference or

"pollution" . In the face of increasing electricity grid CKS quality issues, which makes electric quality

research is extremely pressing.

On the other hand, the quality of electricity supply is gradually enterprises and electricity consumers

are of common concern. Since the 1990s into the 20th century, as the semiconductor, computer technology

is developing rapidly, the number of high-tech enterprises have emerged, a large number of computer

control devices and production lines. Quality of electricity put new demands; And the development of the

electricity market to greater awareness of the power supply enterprises : users need is their own needs.

Against this background, the result of poor quality due to electricity users of defective equipment or

parking situation. Quality standards should be seen as electricity. Of course, there are many bad quality of

electricity users to transfer quality sensitivity also varied. One boat, the electric power supply enterprises

of different quality may be a hierarchy, respectively pricing, users can freely choose. But also because of

our failure to achieve quality grain at the present. Therefore, further work is required to improve the quality

of electricity users in the adjacent settlement. With the quality of electricity equipment sensitivity to

changes in electricity, further expand the scope of quality electricity. demanding more detailed

classification. In the new electricity market environment, the quality of electrical energy has become a

power consumption characteristics of such commodities, largely reflects the quality of electricity service.

Therefore, relevant departments are increasing the quality of electrical energy regulation and governance.

These background, the quality of electrical energy research urgent need to promote new technologies

through the application of these new technologies so that the quality of electrical energy from the testing, 2 analysis and monitoring aspects have been improved, thus enabling discovery and rules, and improve the

quality and supply of services.

2.power quality testing new technologies

Electric quality testing is the most direct access to relevant data conversion means, but also the quality

of other follow-up High energy applied research front.

2.1 quality testing of electric current

To monitor the quality of electrical energy to electrical energy is the quality of information of direct

channels, while the instrumentation has many, but most only continuity and stability testing indicators, and

traditional theories based on valid value testing technology because of the time window is too long, only

valid value can not measure accurately describe the actual electricity quality, Thus the need to develop new

detection technologies to meet the following requirements : First, to capture rapid (ms level even ns level)
