提出了一种基于负荷识别的电网电压无功优化控制方案,指出该方案能够准确地识别电网负荷运行情况,结合逆调压要求,给出不同负荷区域的定值整定原则,实时修正控制定值,使电压无功控制与负荷变化实时联动,提高了电压无功的控制效果,达到优化控制的目的。

This paper puts forward a scheme for grid voltage’s reactive power optimal control based on load identification,and points out that the scheme can accurately identify the running situation of grid load,and connecting with the counter-adjusting requirement to voltage,provides the principle of constant setpoint regulation in each load range,corrects and controls the fixed value in real time,makes the real-time interaction between voltage’s reactive power control and the load variation,increasing the control efficiency of voltage’s reactive power control,and realizing the optimal control.
