Description
technical field [0001] The invention relates to the technical field of thermal power unit control, in particular to a thermal power unit control system with a fast load shedding function. Background technique [0002] The fast load shedding (FCB) function is to cut off the external power supply load at the instant of a system failure, maintain the thermal power unit’s operation with the plant power island and quickly restore the power supply to ensure the safety of the unit. Most of the traditional thermal power units in my country do not have the fast load shedding (FCB) function, which makes it impossible for the traditional thermal power units to provide external power that can be restarted quickly when a large-scale power failure occurs in the power system. It is difficult to solve the problem of thermal power unit availability and Economic issues. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art. ...
