化工生产装置防电网波动技术措施及其应用

Countermeasures keeping electric grid from voltage fluctuation and the applications in chemical process units

就电网瞬时波动对化工装置运行造成的的影响进行简要的分析。介绍了一些防止化工生产装置因电网瞬时波动而停车的技术措施,并简要讨论其特点和应用范围。最后,介绍几例在生产装置中的实际应用。

Affects resulted from voltage instantaneous fluctuation of electric grid on the operation of chemical process units are analyzed. Some countermeasures keeping the units from malfuction or cease operation and not affected by voltage instantaneous fluctuation are introduced. The characteristics and the application scope of the countermeasures is discussed. A few examples being applied in the units are introduced at the end of this article.
