摘　　要：在电力系统中,无功电源的合理规划运行是电力系统安全经济运行的保障。衡量电能质量的一个重要指标是系统的电压水平,而系统的无功平衡是保证电压水平的基本条件。对电力系统进行无功优化,就是通过调节相关控制变量,使无功潮流达到合理的分布,以此来保持系统的电压水平和提高系统的电压稳定性,并降低有功网损。介绍了电力系统无功优化的常用数学模型和优化算法,对相关的一些研究内容作了总结,并分析讨论了各种模型和算法的优缺点,是对无功优化的一个综述。In a power system, the rational planning operation of reactive power is a safe and economic guarantee of the power system operation. It is an important index to measure electric energy quality for the system voltage level, and the reactive balenee of the system is a besie condition to ensure the voltage level. For the reactive optimization of the power system, it is to regulate relative control variables to make the reactive current achieve rational distribution, so as to keep the system valtage level and increase the system voltage stability and reduce active power losses. The common mathematical models and optimization algorithms of the power system reactive optimization are presented in the paper. It sums up some related study contents and analyzes advantages and disadvantages of the models and algofithums, which is a summary of the reactive optimization.
