  • Combined cycle power generation plant operating more stably on load change
    Patent number: 6718749
    Abstract: A combined cycle power generation plant includes a gas turbine operating in response to a turbine control signal and a speed control apparatus which outputs the turbine control signal to the gas turbine based on a speed governor control signal for a first time period after an operation of the plant is switched to a system isolated operation. The speed governor control signal is a signal for speed control of the gas turbine, and a switching signal is generated when the operation of the plant is switched to the system isolated operation.
