系统故障条件下分布式电源孤岛运行的探讨

Discussion on islanding operation of distributed power system under system fault

神华宁煤煤制油项目供电系统主要是由国网公司供电,它通过不同等级降压变实现分布式供电系统,项目内设动力站,有发电机等设备。当国网供电系统出现故障时,如何让各工艺分厂利用动力站进行孤岛运行。其中,系统故障下的分布式电源是在系统处于故障状态下,分布式电源如何运行工作的,电源孤岛运行会出现什么样的情况。本文主要探讨供电系统故障时,分布式电源孤岛运行状况分析,孤岛运行对于系统的利弊分析以及如何使公司的动力站在国网供电系统出现问题时进行自我的孤岛供电,减少设备经济损失。

Shenhua Ningxia coal coal oil project of power supply system is mainly composed of the State Grid Corporation of power supply, it realizes the distributed power supply system through different levels of blood pressure, in a power station project, a generator. The power supply system when the network fails, how to make use of the technology of branch power station island operation. Among them, the distributed power supply under the system fault is in the system is in a state of failure, how to operate the distributed power supply, power island operation will appear what kind of situation. This paper mainly discusses the power system fault, analyzing the operation of the distributed power island, the island operation for the analysis of advantages and disadvantages of the system and how to make the company a power station in the power supply system of network problems of power island self, reduce economic loss of equipment.
