摘　　要：为了解决目前电压无功综合控制算法中存在的一些问题,提出了一种将变电站电压无功的实时数据、短期负荷预测结果、电压无功优化控制算法有效结合的新型区域变电站电压无功综合控制方法。该方法由采用静态无功优化数学模型的调度层控制部分和基于负荷预测的变电站层电压无功控制部分构成,调度层控制的无功优化数学模型采用遗传算法进行求解,变电站层电压无功控制通过在短期负荷预测中引入了Kalman滤波理论以提高预测结果的准确性,同时给出了调度层控制与变电站层电压无功控制的具体结合方案。计算实例的计算结果证实了该方法的正确性与可实施性。A novel regional substation voltage and reactive power control algorithm based on real-time data, short-term load forecasting, and optimization algorithm is put forward to solve the problems in current reactive power integrated control algorithm. The algorithm consists of the scheduling layer control section and substation layer reactive power control section, the scheduling layer control uses power optimization model which is solved in genetic algorithm, the substation layer control uses short-term load foresting based on Kalman filter theory in order to improve the accuracy of load forecasting. The concrete combination scheme of scheduling layer control and substation layer control is proposed. The solution of the calculation example indicates the proposed algorithm is correct and feasible.
