配电网无功补偿优化研究

随着电力事业的不断发展，电网日趋复杂，用电负荷日益增长，大量的无功功率在电网中流动增加了配电网网损，降低了电能的电压质量和电网的经济效益。针对配电网的特点，从运行经济性角度出发，采用智能进化算法，找出一个用电网有功功率损耗最小为成本函数的无功补偿配置优化方法，以便确定补偿电容器的最佳安装点和最佳安装容量。获取最优无功补偿方案，最终达到降低配电网有功功率损耗的目的。

No Compensation of Distribution Network Power Optimization

With the development of power industry, power network has become more and more complex, and a large quantity of reactive power resulted from the ever-increasing loads flows into the power network and causes losses, which reduce voltage quality and the economic benefits of power network. In this paper, con- sidering the characteristics of the distribution networks, with the floating-coded genetic algorithm, the authors proposed an optimal capacitor reactive power compensation algorithm with the minimum electrical network loss as the goal. By using this method, the optimal installation position and optimal compensation capacitance of the capacitors are determined.
