摘要
随着近年工业的飞速发展,配电系统架构不平衡及配电变压器的大量使用造成了配电系统三相不平衡。从三相不平衡及无功补偿原理入手,采用相间、分相以及动态补偿的混合补偿策略,并结合混合差分进化法对补偿量进行寻优处理,以保证在配电系统电压补偿中不过补,达到最优补偿效果。仿真分析及工程案例研究显示,混合补偿策略能够有效降低配电系统的三相不平衡度,动态补偿系统的稳定性及有效性较高,具有良好的市场应用前景。
In recent years,due to the rapid development of industry,the imbalance of the power distribution system architecture and the large use of power distribution transformers have caused a three-phase imbalance in the power distribution system.Starting from the principle of three-phase unbalance and reactive power compensation,a hybrid compensation strategy using inter-phase,split-phase,and dynamic compensation is proposed,and a hybrid differential evolution method is used to optimize the compensation amount to ensure that it cannot be used in the voltage compensation of the power distribution system.To achieve the best compensation effect.Simulation analysis and engineering case studies show that the hybrid compensation strategy can effectively reduce the three-phase imbalance of the power distribution system,the stability and effectiveness of the dynamic compensation system is high,and it has a good market application prospect.
