摘　　要：晶闸管STATCOM(static synchronous compensator)可吸收连续可调的无功,且不受电网电压影响。文中首先分析其数学模型;然后采用逆系统方法构造出伪线性系统,并结合滑模变结构控制理论,实现晶闸管STATCOM对负荷的直接无功功率补偿;最后对该控制系统进行计算机仿真。结果表明,文中采用的控制方法具有较好的动态性能和稳态性能,对负载无功变化的适应能力强。The thyristor based static synchronous compensator （STATCOM） can absorb continuously adjustable reactive power and is not affected by power system voltage. The authors analyze the mathematical model of thyristor based STATCOM at first; then a pseudo-linear system is constructed by inverse system method and combining with the theory of sliding mode variable structure control the direct reactive power compensation to power load by thyristor based STATCOM is implemented; finally, the computer simulation of the developed control system is performed. Simulation results show that the developed control method possesses better steady-state behavior and dynamic performance and strong adaptive capacity to reactive power variation of load.
