基于负荷预测的500kV变电站无功优化研究

Research on Reactive Power Optimization of 500 kV Substation Based on Load Forecasting

优化无功率电压需要做到:建立相关函数与约束条件,来选择主线电压的质量与机器运转的次数,目标则选择消耗最低的路径与设备,进行分次地测量用量,每次都要运行目标函数来明确设备所有接头的地点,然后分批次地测量无功功率,同样地运行目标函数来决策出最佳的电容器组。在某500kV的变电站中试运行了最佳的无功策略,通过一系列计算,发现最佳无功电压策略的确可大幅度地提高无功优化的效率,减少了损耗,从而达到了比较满意的运转效果。

For optimizing the voltage and the reactive power of the grid, we need to: the correlation function is established, and the quality of the main line voltage and the number of times the machine runs are selected as the constraints. The target is to select the path and equipment with the lowest consumption and measure the dosage in stages. Function to decide the best capacitor bank.Through a series of calculations, it is found that the optimal reactive power and voltage strategy can improve the reactive power optimization conveniently and quickly, reduce the loss, and thus achieve a more successful operation.
