Title:
GAS TURBINE POWER GENERATION SYSTEM, CONTROL METHOD FOR GAS TURBINE POWER GENERATION SYSTEM, AND CONTROL DEVICE FOR GAS TURBINE POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/098220
Kind Code:
A1
Abstract:
The gas turbine power generation system of the present invention repeats either the supply or absorption of power, in addition to generating power. The gas turbine power generation system is provided with a first rotation shaft, a compressor, a combustor, a first turbine upon which combustion gasses impinge, thereby causing the first turbine to rotate, and driving the first rotation shaft, a rotating electrical machine connected to the first rotation shaft, a governor for controlling the speed of the compressor by adjusting an air volume, a frequency converter for converting a frequency of power, the frequency converter being connected between the rotating electrical machine and a power system via a power line, and a controller for obtaining a request for an output from the gas turbine power generation system and controlling the combustor on the basis of the request. With respect to the frequency converter, the controller performs frequency converter control for changing the rotational speed of the rotating electrical machine on the basis of the request. The rotating electrical machine supplies or absorbs power in accordance with the change in the rotational speed. With respect to the governor, the controller performs governor control for setting the rotational speed to a reference value.
