摘要
直流受端电压稳定性是目前关注的热点,多资源无功功率协调控制可有效提高直流受端系统的电压稳定特性。提出了一种综合考虑多资源配置的无功功率支援方法,综合考虑了交流电网的安全稳定约束,提出了区域电网多资源按优先级进行无功功率支援的计算方法,同时结合发电机、直流及可切负荷等资源的运行特点及其电压支撑特性,提出了一种多资源电压协调控制策略,并通过实际电网数据进行仿真,验证了所提方法和策略的有效性。
The voltage stability of DC receiving terminal has become a focus of current attention,and the multi-resource reactive power coordinated control can effectively improve the voltage stability characteristics of the DC receiving system.This paper proposes a reactive power support method which synthetically considers not only the multi-resource allocation,but also the security and stability constraints of the AC power grid,giving the calculation method of the multi-resource reactive power support according to the priority,and puts forward a multi-resource voltage coordinated control strategy,which combines the voltage support characteristics of the generators,DCs and resettable loads.Finally,the effectiveness of the proposed method and strategy is verified through the simulation of grid actual data.
