摘　　要：无功优化(RPO)是电力系统实现无功功率最优控制,保证电压质量的重要措施。以提高电压质量和降低网损为目标构建了一个基于电网调度自动化(SCADA)平台的无功优化系统。为了满足实际无功优化系统的要求,从工程应用的角度,研究了系统结构、控制方式、设备动作等解决方案。最后采用原对偶内点法对某地区232节点实际电网进行优化计算,结果表明,电压质量改善和网损降低是能够实现的。Reactive power optimization （RPO） is the important measure to achieve the optimal control of reactive power and ensure the voltage quality. A RPO system based on the dispatching automation platform is constructed in the paper. The optimization objectives are to improve the voltage quality and reduce the network loss. In order to meet the requirements of the actual reactive power optimization system, system structure, control styles, equipment action solutions etc are studied from the perspective of engineering application. Finally, prior-dual interior point method is used to compute a 232-buses real electric power network. Results show that the voltage quality improvement and the network loss decline can be achieved.
