| 摘 要： | 首先分析了分布式电源接人配电网的方式、作为等效电源的模式、配电网孤岛运行方式以及它们对配电网供电可靠性的影响,然后根据供需平衡原则,提出配电网孤岛划分策略,在此基础上,建立了计及分布式电源影响的配电网供电可靠性分析计算模型,最后通过对一典型配电网的仿真计算,说明该模型的合理性与有效性.以计算结果表明,分布式电源接入配电网后,可以大大提高配电网供电的可靠性.

| Abstract: | the connecting methods of distributed generation(DG) to the distribution network,the equivalent supply sources modes of DG,the islanded operation manners of distribution network,and their influences on the power supply reliability of the distribution network are analyzed.Based on the principle of supply-demand balance,the dividing strategy for the islanded distribution network is proposed,and the reliability analysis and calculation model for distribution network with DG was established.Simulation proves the model reasonable and effective.Calculaiton results!shows that the interconnetion of DG to the distribution netwok can greatly improve the power supply reliability of the distribution network. |
