초록

The invention suppresses the production of thermal stress in power generating equipment and the unstable behavior of the power generating equipment due to the variation of system frequency and stabilizes the system frequency. A power plant load control system controls the operation of a power plant equipped with a gas turbine comprising a combustor (1) and a turbine (3), and a power generator (5) disposed coaxially with the turbine. The power plant load control system comprises a governor load control unit (100) for determining a governor instruction (10...

청구항

[ What is claimed is:] [1.]1. A power plant load control method to be applied to a power plant provided with a turbine and a power generator coaxially connected to the turbine to control load on the turbine so that a system frequency may be stabilized, said power plant load control method comprising the steps of:producing a governor load control signal on the basis of a load dispatching instruction given according to the change of the system frequency to the power plant, generated power, measured shaft speed and a predetermined system speed droop ratio;d...
