Reactive compensation control device and control method thereof

The invention discloses a reactive compensation control method which is characterized by comprising the following steps: acquiring power grid data; processing the power grid data to obtain a power factor; comparing the power factor with a set value, and performing switching operation of switching first according to a comparison result; and judging whether the capacitor branch is good or not, and correspondingly calling the standby branch according to a judgment result. By judging the quality of the capacitor branch and automatically calling the standby branch, the use stability and reliabilityof the capacitor branch are improved, the service life of the compensation device is prolonged, and the maintenance period of the reactive power compensation device is shortened. 本发明公开了一种无功补偿的控制方法，其特征在于，包括：采集电网数据；对电网数据处理，得到功率因数；将功率因数与设定值进行对比，根据对比结果进行先投先切的投切操作；对电容支路的好坏进行判断，根据判断结果进行相应的调用备用支路操作。通过判断电容支路的好坏，并进行备用支路的自动调用，不仅提高了电容支路的使用稳定性和可靠性，还延长了补偿装置的使用寿命，缩短无功补偿装置的维护周期。
