| 摘 要： | 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. |
