基于磁阀式可控电抗器的变电站电压无功控制策略的研究

针对变电站存在的无功倒送和电容器组只能进行分级无功补偿的缺点,分析了基于自励磁磁阀式可控电抗器的动态无功补偿方案,利用MATLAB进行仿真,以实时计算为基础,实现电抗器的连续平滑调节,再配合固定电容器组具有抑制电压波动,稳定功率因数,快速补偿无功的特点,满足变电站无功电压综合控制的需要。

Study on Substation Voltage Reactive Power Control Strategy Based on Magnetic Valve Controllable Reactor

Aiming at demerits of substation such as reactive power delivers and grading reactive power compensation of ca- pacitor bank, this paper analyzes dynamic reactive power compensation scheme based on self-excitation magnetic valve con- trollable reactor which uses MATLAB for simulation and to realize continuous smooth adjustment on the basis of real-time calculation. Meanwhile, by cooperating with characteristics of fixed capacitor bank such as restraining voltage fluctuation, stabilizing power factors and rapidly compensating reactive power, it is able to satisfy requirement for comprehensive control on reactive voltage of substation.
