For the ill conditioned load flow caused by the error produced in the transformation from electricity quantities to average power, direct current load flow and sensitivity vector are presented to find out the ill node, then by adjusting the load curve and generation curve in a certain principle, which is shown in detail with several flow charts, a new operation mode is reestablished to ensure the convergence of the calculation. Optimal multiplier method is proposed to work out the least square solution according to ill conditioned structural power network. The electricity quantities flow method enhances the reliability and accuracy of the calculation of the power transmission losses.
该方法可根据当前输电网中各个变电站24小时的电量记录,利用电量潮流计算对输电网总线损和各条线路损耗进行计算,使计算的精度满足降损措施分析和指标考核的要求;并且对于由负荷出力曲线转化成平均功率计算潮流时引入的误差,进而导致潮流计算不收敛的情况,采用直流潮流法,依据相角对有功功率的灵敏度向量判断出"网络异常点",并且给出了解决此种情况的方法流程图;针对结构病态的电力系统潮流计算不收敛的情况,运用非线性约束优化方法中的最优乘子法求解潮流方程的最小二乘解,从而解决了电量潮流法计算理论线损时的收敛性问题,增强了该方法的适用性。
