摘　　要：介绍了一种TSC综合型动态无功补偿装置,该装置采用定点DSP芯片TMS320LF2407A 作为控制器的核心,通过快速傅里叶变换准确检测出电网中的各项参数,投切补偿电容器时以各相所需的无功功率为控制量,以固态继电器为投切开关,三相共补与分补相结合,实现对三相不对称冲击负荷的快速响应,有效地防止过补偿和投切振荡。TSC synthetical type dynamic reactive power compensation device based on DSP is introduced. The device adopts fix-point DSP TMS320LF2407A as the core of the controller. The factors of power system are measured accurately by fast fourier transform. Capacitor switching by SSR depends on the var needed for each phase. Three-phase compensation and phase-splitting compensation is combined. The device responds rapidly to percussive load of three unbalanced phases. It can prevent over-compensation effectively and withhold switching oscillation.
