阐述用StatCom实现配电系统的无功功率补偿、相应的系统参数和控制参数对补偿效果的影响,并从控制策略上对配电系统中负载和传输线阻抗的变化进行分析。针对配电系统的特殊性,说明当负载发生大幅变化对控制系统的动态跟踪性能,并进行了大量的仿真。讨论了在给定线路阻抗和负载波动条件下StatCom的实验效果。
The effects of reactive power compensation, corresponding system parameters and control parameters on the compensation effect of the power distribution system with StatCom are expounded. And the changes of load and transmission line impedance in the power distribution system are analyzed from the control strategy. In view of the particularity of the power distribution system, the dynamic tracking performance of the control system when the load changes drastically and a large number of simulations are carried out. The experimental results of StatCom for a given line impedance and load fluctuation are discussed.
