The present invention relates to a gas-steam combined cycle centralized heat supply device and a heat supply method. The gas-steam combined cycle centralized heat supply device comprises a gas-steam combined cycle system connected with a thermal station through a heating network return water heating system; the gas-steam combined cycle system comprises a gas turbine connected with a direct contact type flue gas condensation heat exchanger and a steam turbine via a waste heat boiler; the thermal station comprises a hot water type absorption heat pump and a water-water heat exchanger; the heating network return water heating system comprises a steam type absorption heat pump for recovering flue gas waste heat and a steam-water heat exchanger. The present invention can be widely applied to the industry of power plant waste heat recovery.

Gas-steam combined cycle centralized heat supply device and heat supply method

The Application relates to a combined heating power and cooling apparatus with energy storage for an active distribution network and its operating method. The apparatus is comprised of a generation apparatus, a generator, a waste heat recovering and absorbing heat pump, a high temperature flue gas-water heat exchanger, a medium temperature flue gas-water heat exchanger, a low temperature flue gas-water heat exchanger, an energy storing electric heat pump, a high temperature energy storing canister, a low temperature energy storing canister, a cooling tower, a number of circulating water pumps and a number of valves. The operating method changes the traditional operation modes of the system 'determining electricity based on heat' and 'determining electricity based on cooling', causes the system to regulate power of the generated electricity on grid, participate in the regulation of grid load, solve the problem of a limited ability of generation peak regulation due to the inter-coupling of power generation, heat supply and cooling supply.

Combined heating power and cooling apparatus with energy storage type adapted to an active distribution network and its method
