| 摘 要： | 配电网三相负荷不平衡对供电电网以及变压器等电器都会造成不利的影响，致使低压电网的可靠性和稳定性差，线损增高。结合工程实例，利用遗传算法在Matlab环境下求解出一个最优的负荷分配方案，从而使三相不平衡电路尽量接近三相平衡状态，减小零序电流，减少配网损耗，使系统能够在更加经济的状态下运行，达到节能效果。

| Abstract: | The unbalanced three-phase load has negative effects on the power supply and the electrical appliances like transformers, resulting in poor low-voltage grid reliability and stability with higher line loss. Combined with engineering examples, this paper adopts the use of genetic algorithm in Matlab environment, establishing an opti-mal load distribution scheme to keep the three-phase unbalanced circuit close to the three-phase equilibrium state. It finds out that the system can be more economical in running state as the zero-sequence current decreases and distribution network losses are reduced. |
