摘　　要：通过建立机网协调控制系统,运用一系列的自动化手段使本厂区具备在外网出现故障时,干熄焦余热汽轮机发电带厂区重要负荷孤网运行。待外网恢复正常时,通过自动化装置进行并网运行,尽快恢复生产,从而加强并巩固焦化厂的用电可靠性,从源头上杜绝外网波动造成的大面积停电事故。This paper studies a turbine-grid system through which an isolated power grid fed from CDQ steam turbine can be automatically switched over in running for critical electric consumers inside coke plant in case of power failure in the external grid.When the external power grid is resumed,the isolated grid can be automatically switched to the integrated grid to restore normal production as the quickest so that the potential risk of large-scale power outage due to the external grid failure can be avoided since the above-mentioned measures have strengthened the power grid stability of the coke plant.
