氯碱企业外电网故障时保证发电机组孤网运行的措施

Measures to ensure isolated network operation of generator units of chlor-alkali enterprises in the case of failure of external power grid

针对某公司供电系统的薄弱环节,制定发电机组孤网运行方案,提出保证发电机组孤网运行的措施,在外电网波动或故障停电的情况下让发电机与外电网解列,孤网运行,解决外电网失电等外界因素致使企业电网停电的问题,提高了电力系统的可靠性,达到了连续供电、确保安全生产的目的。

Schemes for isolated network operation of generating units were formulated in view of weak links in the power supply system of a certain company. Measures to ensure isolated network operation of generator units were proposed. In the ease of fluctuation or fault interruption of external power grid, generating units were disconnected with external power grid and their operation was isolated. Then the problem of power interruption in the company due to external factors such as breakdown of external power grid was solved. The reliability of power system was increased. The aim of continuous power supply to assure safe production was attained.
