A Study on the Automatic Optimization Method of Voltage Regulation Gain of the Dynamic Reactive Power Compensator
The parameters of the voltage regulator for dynamic reactive power compensation devices can only maintain a fast and stable response within a certain short-circuit capacity range.When the regulator is applied to large-scale new energy gathering stations,due to the wide range of system short-circuit capacity,its response may become very slow or oscillate.This article proposes a method for automatically optimizing the voltage regulation gain of dynamic reactive power compensation devices.The effects of voltage waveform distortion,current waveform distortion,and other automatic voltage compensation devices on the calculation results of short-circuit capacity in the actual engineering are analyzed and simulated and solutions are provided.A simulation study is conducted on the proposed gain automatic optimization method in RTDS,and the results show that the designed voltage regulation gain automatic optimization method can automatically adjust and optimize the gain according to system requirements.
