Abstract

The invention discloses a fuel gas-steam-thermoelectricity cooperative system and method based on heat storage steam adjustment. The system comprises an air compressor, a gas turbine, an electric generator, a heat accumulator, a boiler, a chimney, a low-pressure steam pocket, a high-pressure steam pocket, a main steam pipe, a steam condenser, a make-up pump, a connection pipeline and an auxiliaryvalve. Thermoelectricity system supply of an original gas turbine in a low-load or even halt state is improved by arranging the heat accumulator and utilizing high-temperature flue gas of the gas turbine for heat accumulation, the requirements of the user side for hot steam are met, the gas turbine set thermoelectricity coordination ratio is improved, meanwhile, the system economy is improved, andthe application prospect is quite good.

Description

technical field

[0001] The invention relates to a gas-steam combined cycle and heat storage technology, in particular to a gas-steam heat-electricity synergy system and method based on heat-storage steam regulation. Background technique

[0002] With the increasing proportion of new energy power generation systems on the power supply side in the power supply system, the load fluctuations on the power supply side are increasing. At the same time, the fluctuations in energy demand on the demand side have always existed, resulting in The peak shaving performance requirements of the power supply system are getting higher and higher, and more and more traditional power stations are also required to participate in peak shaving.

[0003] Gas turbine, as the earliest unit type involved in peak regulation, has been widely recognized by the market due to its convenient start and stop and good flexibility. At the same time, in order to improve the energy utilization efficiency of gas ...
