风电汇集站可控高压并联电抗器电压控制策略研究

Research on Voltage Control Strategy of Controllable Shunt Reactor in Multiple-Converging Wind Power Staiton

对某500 kV风电汇集站500 kV可控高压并联电抗器(以下简称CSR)的电压控制策略进行仿真分析。将多个500 kV母线电压控制定值及高中压侧常用的几种变比进行多种组合,在风机出力0~100%过程中进行仿真试验,并求出区域无功综合利用率,以此确定受控母线的电压控制定值和主变压器变比,为风电汇集站CSR电压控制策略的制定提供依据。

Taking a multiple-converging wind power station which planed to adopt the CSR on its 500 kV bus as an example,simulation was carried out for the voltage control policy of CSR.Based on different combinations of control set points of 500 kV bus and transformer tap,simulation of wind turbine output varied from 0 to 100%were carried out.Taking the comprehensive utilization of reactive compensation equipments as the evaluation criterion,the setting value of controled bus and the transformer tap were determined,which offered the reference for developing the voltage control policy of CSR.
