油田井工厂分布式电源孤岛分析

Analysis of Distributed Power Source Island of Oilfield Well Factory

防孤岛保护是油田井工厂多能互补系统的关键技术,由此对油田井工厂分布式电源孤岛进行分析。建立由光伏发电、网电、风力发电、燃气轮机等设备组成的油田井工厂分布式电源孤岛仿真模型,进行不含储能电池的分布式电源孤岛瞬时有功功率过剩仿真分析,检验采用电压相位偏移与电压频率偏移综合进行孤岛检测判断的有效性。

Anti islanding protection is a key technology for the multi energy complementary system of oilfield well factory.Based on this,the distributed power source island of oilfield well factory was analyzed.A simulation model for distributed power source island of oilfield factory was established consisting of photovoltaic power generation,grid power generation,wind power generation,gas turbine,and other equipment.Simulation analysis on the instantaneous active power excess of distributed power source island without energy storage battery was carried out,and the effectiveness of island detection by using voltage phase offset and voltage frequency offset was judged.
