The dynamic response characteristic of primary frequency regulation(PFR) for M701F gas-steam combined cycle unit can not reach the performance standards.Based on the reason analysis for this
some optimizations were carried out
such as selecting the speed control mode in main control system to improve the response speed of primary frequency regulation
narrowing the regulation dead band and increasing the regulation range in automatic load regulation(ALR) system.Results showed that
after optimization
the response time of PFR was between 1 s and 2 s when the frequency variation of power network exceeded the unit PFR dead band.Within 45 s
the actual PFR amount exceeded 70% of the theoretical frequency regulation.Therefore
the optimized PFR function totally satisfied the requirements of power dispatching on the PFR performance.
