Title:
HEAVY-DUTY GAS TURBINE HAVING VARIABLE-SPEED SYNCHRONOUS MOTOR DRIVEN COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2019/200975
Kind Code:
A1
Abstract:
A heavy-duty gas turbine, comprising a compressor (1), a variable-speed synchronous motor (2), a static excitation device (3), a variable-frequency power supply (4), a combustion chamber (5), a gas turbine (6), and a generator (7). The turbine-style compressor (1) is driven by the variable-speed synchronous motor (2). Rotation speed is adjusted throughout starting, low-load, intermediate load, and high-load operation, so that the turbine-style compressor (1) operates with high efficiency at each level. The entirety of the shaft power generated by the gas turbine (6) is converted into electrical energy by the corresponding generator (7). The present gas turbine is efficient and energy-saving, and features good controllability, flexible operation, rapid start-up and shutdown, and strong primary frequency regulation capabilities.
