| 摘 要： | 本文介绍了一种新型TSC动态无功补偿装置,该装置以TMS320LF2407A作为控制器的核心,以电流互感器、电压互感器为采样装置,运用快速傅里叶变换准确检测电网中的各项参数。投切电容以电力系统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,可以有效地防止无功过补偿和电容投切时造成电网震荡。

| Abstract: | TSC type dynamic reactive power compensation device based on DSP is introduced in this paper .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 responeds rapidly to percussive load of three unbalanced phases. It can prevent over-compensation effectively and withhold switching oscillation. |
