摘要：【中文】本发明涉及一种基于电压趋势预测的500‑220kV区域电网自动电压控制方法，属于电力系统自动电压控制技术领域。该方法在每个自动电压控制周期到来时，读入获取500‑220kV区域电网下级各220kV变电站超短期负荷预测，并根据超短期负荷预测计算未来500‑220kV区域电网的潮流和500‑220kV区域电网内220kV母线的电压值的波动幅度。该方法进一步根据电压值的波动幅度计算500‑220kV区域电网内220kV母线的电压安全域限值，并输入到自动电压控制系统中实现预防控制。采用本方法可对500‑220kV区域电网下级220kV变站在负荷未来变化过程中造成的220kV母线电压越限进行预防控制，提高了电网安全稳定性。 【EN】The invention relates to an automatic voltage control method for a 500-220kV regional power grid based on voltage trend prediction, and belongs to the technical field of automatic voltage control of power systems. According to the method, when each automatic voltage control period comes, ultra-short term load prediction of 220kV transformer substations of a 500-plus-220 kV regional power grid is read and obtained, and the trend of the 500-plus-220 kV regional power grid and the fluctuation amplitude of a 220kV bus voltage value in the 500-plus-220 kV regional power grid in the future are calculated according to the ultra-short term load prediction. The method further calculates the voltage safety domain limit value of the 220kV bus in the 500-220kV area power grid according to the fluctuation range of the voltage value, and inputs the voltage safety domain limit value into the automatic voltage control system to realize preventive control. By adopting the method, the 220kV bus voltage out-of-limit caused by the future change process of the load of the 220kV substation in the lower level of the 500-plus-220 kV power grid can be prevented and controlled, and the safety and stability of the power grid are improved.
