Abstract

The invention discloses a fuel gas and steam combined power device with peak regulation and energy storage functions and a control method thereof. The fuel gas and steam combined power device comprises a first power generator, a steam turbine, an axial flow compressor, an axial flow turbine and a second power generator. The first power generator is connected with one end of a first rotating shaft, and the other end of the first rotating shaft is connected with one end of a second rotating shaft through a first 3S clutch; the other end of the second rotating shaft is connected with one end of a third rotating shaft through a second 3S clutch, and the other end of the third rotating shaft is connected with the second power generator; and the steam turbine is installed on the first rotating shaft, the axial flow compressor is installed on the second rotating shaft, and the axial flow turbine is installed on the third rotating shaft. The fuel gas and steam combined power device is used for conducting corresponding regulation when the power load is changed so as to adapt to the load change, peak shifting and valley filling are achieved, and the problems of difficult peak regulation, insufficient flexibility, low energy utilization rate and the like in an existing power plant can be well solved.

Description

technical field [0001] The invention relates to the technical field of combined power cycle devices, in particular to a gas-steam combined power device with adjustable peak energy storage and a gas storage tank. Background technique [0002] Under the dual pressure of increasing scarcity of traditional energy sources and deteriorating environment, people's demand for electricity is increasing increasingly, but there are obvious fluctuations in the load of the power grid. At present, conventional energy sources such as thermal power based on traditional fossil energy are still used for peak regulation. This peak-shaving measure is slow in action, consumes a lot of energy, and is not practical. Contents of the invention [0003] The object of the present invention is to provide a gas-steam combined power plant capable of peak regulation and energy storage and its control method, so as to solve the problems of difficult peak regulation and low energy utilization rate in exist...
