摘要
為了補償電網(wǎng)上的無功功率，本文提供了一種晶閘管控制電容器（TSC）用控制器的控制方法和具體硬件設(shè)計。隨著電網(wǎng)的波動，控制器通過測量系統(tǒng)電壓、電流，計算出無功功率、功率因數(shù)，再與測出的電容器上電壓大小的比較，經(jīng)單片機運算出電容投切的分組與方式，對電網(wǎng)進行無功補償。在采樣電路上相位偏差補償電路的設(shè)計，消除了電路內(nèi)部產(chǎn)生的相位偏差。控制器的硬件電路設(shè)計，在做到快速、敏捷地補償容量,提高電網(wǎng)的功率因數(shù)的前提下，不僅不發(fā)生過補償，而且不發(fā)生投切振蕩,不產(chǎn)生沖擊性過渡過程。

ABSTRACT
A method of control and detailed hardware designation of the thyristor switch capacitor (TSC) controller is presented in this paper. After measuring the voltage and the current of network and work out the power of it, comparing to the voltage on the capacitors, the controller may group the capacitors and choose optimal mode to switch the capacitors into the network, which can compensate the reactive power of the network, according to varying load. The phase compensation designation in the measuring circuit can eliminate the warp in the electrocircuit and the compensation of the reactive power can be realized quickly by the hardware circuit of the control system, without reactive power reversing and switching oscillating.

KEY WORDS: reactive power compensation, TSC controller, switching the capacitor, phase compensation
