摘要
电压是衡量电能质量的重要指标,电压质量对电力系统稳定运行、降低线路损耗、保证工业和农业的安全生产、提高产品质量、降低用电损耗都有直接影响,因此保证电压质量是电力系统设计和运行的重要任务。受端电网电压的稳定控制也一直是困扰运行的难点和热点研究问题。论文基于廊坊电网的实际案例,研究设计了在220kV策城变电站的110kV母线上安装并联电容器,提高电网的补偿能力、降低变压器自身的损耗等并可缓解廊坊地区的无功紧缺状况,提高廊坊地区抵御电网事故的能力。
无功优化也是电力系统安全经济运行研究的一个重要组成部分。无功优化控制是以提高电压合格率、降低电网损耗为目标。论文设计了廊坊电网全局电压无功优化控制系统,该系统采用了电网的实际结构参数和运行参数进行潮流的仿真计算,对地区电网进行全局优化控制,并将理论分析数据与实际监控数据进行综合考虑,从全局角度对地区电网进行优化,而且采用先进模型算法、改进遗传算法,将计算机技术与电网实际运行情况有机结合,增强了系统电压稳定性。通过对SCADA数据和高压线路充电功率的修正,显著提高了无功优化控制的准确性和有效性,取得了比较好的效果。
