摘要
西电东送是我国的重要能源战略,其运行方式及各输电通道的功率分配不同,会产生不同的输电损耗。为了更有效地降低线损率,建立了西电东送交直流输电最优损耗模型,采用序列二次规划(SQP)优化算法,获取各交直流通道的最优功率分配。全年线损率优化计算结果为5.2%,比全年线损率普通方法预测结果5.76%有明显的下降。
West-to-East Power Transmission is a great energy stratagem in China, and can be carried out with defferent ways that have different power distributions and power losses to the lines. This article proposes a calculation model to determine the power distribution for each HVDC transmission line. The power distribution is optimized with algorithm SQP to get a minimized total power loss, resulting in a year-round power loss rate of 5.2% that is obviously lower than 5.76% evaluated with the gerneral way.
