摘要
为了补偿电网上的无功功率，本文提供了一种晶闸管控制电容器（TSC）用控制器的控制方法和具体硬件设计。随着电网的波动，控制器通过测量系统电压、电流，计算出无功功率、功率因数，再与测出的电容器上电压大小的比较，经单片机运算出电容投切的分组与方式，对电网进行无功补偿。在采样电路上相位偏差补偿电路的设计，消除了电路内部产生的相位偏差。控制器的硬件电路设计，在做到快速、敏捷地补偿容量,提高电网的功率因数的前提下，不仅不发生过补偿，而且不发生投切振荡,不产生冲击性过渡过程。
关键词：无功补偿,TSC控制器,电容投切,相位补偿
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
