摘　　要：随着非线性负载在电网中的日益增多,为电网注入了大量的谐波电流,如何解决谐波污染问题成为了一个紧要的课题。静止同步补偿器(Static Synchronous Compensator,STATCOM)能够同时实现无功补偿与治理电流谐波,且运用广泛,技术成熟,是一种切实适用的电能质量综合治理方案。分析了STATCOM进行无功补偿以及谐波电流补偿的原理及控制策略,并就电网向非线性负荷供电问题建立模型,运用PSCAD进行仿真。仿真结果表明,STATCOM能够良好的补偿无功与谐波电流,能够对电能质量进行综合治理。A large number of harmonic currents are injected into the grid with the increasing non-linear load in the grid ; therefore, it has become a critical issue to find the solution to the harmonic pollution problem. STATCOM （ static synchronous compensator）, wide in application and mature in technology, can simultaneously achieve reactive power compensation and harmonic currents governance, thus a practical comprehensive scheme for power quality control. This paper analyzes the principle and control strategy of reactive power compensation and harmonic current compensa- tion based on STATCOM, establishes the model for supplying power to the nonlinear loads, and simulates by using PSCAD. Simulation results show that STATCOM can meet the need of reactive power compensation and harmonic cur- rents governance, practical in comprehensive power quality control.
