分布式电源接入配电网可靠性研究

Studies on reliability for distributed generation connected to distribution network

简单介绍了分布式电源(DG),分析了DG的并网方式、接入方式和运行方式对配电网可靠性的影响,指出不同方式对配电网可靠性的影响各不相同。并在此基础上,研究了DG的可靠性模型和含DG的配电网孤岛划分。最后,从可靠性指标方面对算例进行分析计算,验证DG接入配电网的可靠性。

The concept of distributed generation （DG） was introduced, the impacts of the synchronization mode, connection mode and operation mode that DG connected to distribution network on the reliability of distribution network were analyzed, pointing out that different ways have different influences. On this basis, the reliability model for DG and islanding scheme for distribution network containing DG were studied. The example analysis was taken in the aspects of reliability index to test and verify the reliability for DG connected to distribution network.
