摘　　要：分析了谐波对配电网安全经济运行的影响,介绍了电容器优化配置的数学模型及求解方法,建立了以谐波畸变电压水平和网损为目标的数学模型,并采用遗传算法进行求解,获得控制策略。经算例验证该方法既考虑了电容补偿的经济性,又考虑了抑制谐波的需要,可充分满足系统在运行安全和电能质量方面的要求。Analysis was made to impacts of harmonics on distribution network safety economic operations. Introduction was made to mathematical model and solving method for optimized disposition of capacitors. This paper built up a target mathematical model of harmonic voltage distortion level and network loss and adopted the genetic algorithm to carry out solution, obtaining the control strategy. After calculation example, it is verified that the method takes the economy of capacitance compensation into consideration, as well as the need of harmonic suppression, which meets the requirements of the system in aspects of operation safety and power quality.
