Research on Dynamic Response Time Test System and Method of Reactive Power Compensation Device

Abstract

In the actual enterprise production and inspection process, we found that there is a certain error in the dynamic response time detection method specified in the standard. For the fast response compensation device, the deviation is large, so it is urgent to study and improve the dynamic response test method. Especially for the dynamic reactive power compensation device with millisecond fast response, its input mode, the processing speed of the controller and the calculation method will affect the dynamic response time. In order to solve the shortcomings of the existing technology, this paper proposes a dynamic response time test system and method for reactive power compensation device. By introducing electronic load to generate periodic impulse current waveform, it can not only avoid the impact transient problem of inductive load, but also generate intermittent impulse current waveform, which is convenient to test the dynamic response time after switching off, which greatly improves the test accuracy. The simulation results show that the method can test the dynamic response time of tens of milliseconds more effectively and quickly.
