具有谐振抑制功能的新型SVC拓扑设计及控制方法

摘要

The topology structure and control method of a new type of static var compensator are proposed.To improve the compensation performance of the device,repetitive control is introduced.Then a new static var compensator system is designed for a 10 MVA non-controlled rectifier load in a 10 kV power system.Simulation results show that the new type of static var compensator can suppress resonance between passive filter and the system with high harmonic compensation precision and fast response.The static var compensator is suitable for high voltage and high capacity reactive power and harmonic compensation application.%提出一种新型静止无功补偿器的拓扑结构及相应的控制方法。为了提高装置的补偿性能,引入了重复控制。针对10kV电网系统的10MVA不控整流负载,设计了新型静止无功补偿系统。仿真结果表明：新型静止无功补偿器能有效抑制无源滤波器与电网发生的谐振,具有谐波补偿精度高、响应快的特点,适用于高压大容量无功功率和谐波补偿的场合。
