摘要
由于对电能质量、保护等方面的影响以及相关并网标准和政策的缺失,在传统配电网的用户侧大规模接入分布式发电单元的应用模式尚未得到推广应用。文中通过对北方某产业园区多种DG接入方案进行了仿真,从电压分布、电网损耗、谐波含量和短路保护四个方面分析了该产业园区在用户侧接入DG后对配电网产生的影响。研究表明,在配电网中接入适当容量的DG对整个配电网的保护控制和运行不会产生负面影响,反而可以有效提高电压质量,减少网络损耗。
Distributed power generation technologies have gained rapid development in the past few years. However, concerning to the aspects of power quality, protection and so on, while lacking of related standard, consumer-side distributed generation （DG） has not been widely used. This article did some simulation on the way to incorporate distributed generations into a consumer, and analyzed the influence on the aspects of voltage distribution, power loss, humorous wave, protection that the DGs did to the power grid. The research found out that consumer-side DGs can be one of available ways to achieve the main goals of smart grid.
