摘要

为了调查东莞站STATCOM在电网不对称故障下暂态启动过程中发生的直流过压闭锁事件原因

解决直流过电压问题

需对STATCOM的直流电压控制策略进行分析和优化。通过对STATCOM装置级控制策略进行分析

指出了电容电压主要由直流电压控制环节的PI参数和锁相环相角决定

提出了改变直流电压控制环的比例积分系数和增加相位补偿的优化算法。基于东莞站STATCOM实际的参数

利用PSCAD/EMTDC仿真平台建立包含STATCOM装置的东莞站电网等值模型。通过仿真计算

对比了不同PI参数下直流过电压水平

以及增加相位补偿前后的直流过电水平。仿真结果表明

适当增大直流电压环控制器的PI参数和对锁相环角度进行补偿均可抑制直流过压

两者相结合更是在保证装置稳定性的前提下

可以将直流过压水平从121%降至113%。通过控制策略优化

有效解决了东莞站STATCOM的直流过电压问题。

Abstract

In order to investigate the causes of DC voltage blocking event during the STATCOM transient start–up under the power grid asymmetric faults

and to solve the DC overvoltage problem

the DC voltage control strategy of STATCOM must be analyzed and optimized. Through analyzing the device level control strategy

we pointed out the capacitor voltage was mainly determined by the PI parameters of PI DC voltage control link and phase –locked loop phase angle. Moreover

we proposed the way of optimizing the DC voltage control loop proportional integral coefficient and increasing the phase compensation. Based on the actual parameters of Dongguan substation STATCOM

the power grid simulation model of Dongguan substation STATCOM was built in PSCAD/EMTDC. By simulation

the levels of DC over voltage under different PI parameters were compared

and the levels of DC before and after phase compensation were also compared. Simulation results show that both PI parameters optimization and phase compensation can reduce the DC over-voltage level. A way of combining the PI parameter optimization and the phase compensation is adopted

which can decrease the DC overvoltage level from 121% to 113%. With the DC voltage control strategy optimization

the problem of STATCOM DC overvoltage is effectively solved.
