摘要： 针对在电力系统网络中,大量电机负荷及大功率设备的投入,出现的功率因数较低、电压波动较大等问题,本文在详细分析无功补偿的相关理论和算法的基础上,研究一种基于STM32的晶闸管投切电容器(TSC)无功补偿控制系统,包括补偿方案、控制算法以及控制器的硬件设计和软件设计等。该系统主控芯片采用STM32芯片,执行模块采用CF6G-3型可控硅触发控制器,信号的采集采用功率测量芯片CS5463,并在控制策略上对常规的九区图做了改进,避免设备的误动作与投切振荡现象的发生,对无功功率进行实时动态补偿。实验结果表明,所设计的无功补偿控制器能够控制电容器准确快捷投切,测量数据精确,补偿效果明显,有效地改善了电网电压供电水平,提高了功率因数,并实现系统在无人值守下的安全高效运行。

Abstract: As the equipment of high power and motor load are increasingly put into electric power system, the demand on the quality of power supply is enhanced, such as low power factor and large voltage fluctuation etc. After analyzing the theory and algorithm of reactive power compensation in detail, a system based on STM32 thyristor switched capacitor (TSC) reactive power compensation control is stadied, which includes compensation, control algorithms of nine-zone diagram, controller hardware design and software design. STM32 chip is accepted as the main control chip. CF6G-3 type of silicon controlled trigger controller is used in executing module and CS5463 power measurement chip is used in signal acquisition. An improved nine-zone diagram control strategy is selected to avoid misoperation and switching oscillation phenomenon, so that the system can carry out real-time dynamic compensation of reactive power. The experimental results show that, this TSC system can realize a faster and more accurate measurement and switching, which lead to an obvious effect of compensation and a safe and efficient automatic operation of the system.

Key words: STM32, TSC, reactive power compensation, nine-zone diagram
