摘　　要：为了加强对变电站电压降损问题的控制,提升装置及设备的控制速率,营造更加稳定、安全的无功自动控制环境,采用自适应粒子群算法,提出一种变电站电压无功自动控制方法。设定无功补偿点,进行电压上下限自适应标定,构建多变粒子无功自适应电压控制模型,建立自适应惯性控制机制,采用APSO-rand多目标控制实现变电站电压无功自动控制。最终测试结果表明,所设计的自适应粒子群自动控制测试组得出的降损率相对较低,始终保持在8%以下,证明所提方法在实现无功自动控制工作中,对变电站的自动控制速率较高,误差小,控制效果更佳,具有实际的应用价值。In order to strengthen the control of substation voltage loss,improve the control speed of devices and equipment,and create a more stable and safe reactive power automatic control environment,using the adaptive particle swarm algorithm,an automatic control method of substation voltage reactive power is proposed.The reactive power compensation point is set,and the upper and lower limits of voltage are adaptively calibrated.A multi variable particle reactive power adaptive voltage control model is built,an adaptive inertial control mechanism is established,and APSO rand multi-objective control is adopted to achieve automatic voltage and reactive power control of substation.The final test results show that the loss reduction rate obtained by the designed adaptive particle swarm automatic control test group is relatively low,and it is always kept below 8%,which proves that the proposed method has a high automatic control rate,small error and better control effect for the substation in the realization of reactive power automatic control,which has practical application value.
