At the same time, the hot tank outputs molten salt into the molten salt-water heat exchanger, and the feed water is heated by the molten salt-water heat exchanger, and the heating effect is better.

At the same time, the primary return water of the heating network output by the primary return water pipe 15 enters the water side of the molten salt-water heat exchanger 8 for heat exchange and temperature increase, and then enters the primary inlet water pipe 16 of the heating network.

[0041] It should be noted that heating cannot be guaranteed under special operating conditions such as long-term shutdown of the gas unit, FCB operating conditions, load shedding conditions, or when the gas unit needs to be shut down due to on-site demand during the heating season but cannot be shut down to ensure heating, the gas unit is shut down or the gas unit load is extremely low and heating cannot be guaranteed. The wind power is passed into the electric heater of the heat tank 5 in advance to heat the molten salt. The heated molten salt replaces the extraction steam of the steam turbine 13 to heat the primary side return water of the heating network, and produces hot water for heating.

[0042] Embodiment 2

[0043] On the basis of Example 1, an electrolytic cell 3 is added. Specifically, the heating system of the gas turbine coupled with wind power in the non-operating condition in this embodiment includes an electrolytic cell 3, a wind turbine 4, a hot tank 5, a molten salt-water heat exchanger 8, a cold tank 7, a primary-side return water pipe 15 of the heating network and a primary-side inlet water pipe 16 of the heating network; the output end of the wind turbine 4 is connected to the power interface of the hot tank 5 and the power interface of the electrolytic cell 3, the outlet of the hot tank 5 is connected to the molten salt side inlet of the molten salt-water heat exchanger 8, the molten salt side outlet of the molten salt-water heat exchanger 8 is connected to the inlet of the cold tank 7, the outlet of the cold tank 7 is connected to the inlet of the hot tank 5, the outlet of the primary-side return water pipe 15 of the heating network is connected to the water side inlet of the molten salt-water heat exchanger 8, the water side outlet of the molten salt-water heat exchanger 8 is connected to the primary-side inlet water pipe 16 of the heating network, and the hydrogen outlet of the electrolytic cell 3 is connected to the air inlet of the gas turbine 1.

[0047] The working process of this embodiment is:

[0048] When wind power generation has "off-peak electricity" and "junk electricity" due to its own characteristics, and this part of electricity is often not effectively used and is wasted, the electricity generated by the wind turbine 4 is sent to the hot tank 5 to heat the molten salt, and at the same time sent to the electrolytic cell 3; the molten salt output from the hot tank 5 enters the molten salt side of the molten salt-water heat exchanger 8 to release heat, and then enters the cold tank 7, and the molten salt output from the cold tank 7 enters the hot tank 5 to continue heating. At the same time, the primary return water of the heating network output by the primary return water pipe 15 enters the water side of the molten salt-water heat exchanger 8 for heat exchange and temperature increase, and then enters the primary inlet water pipe 16 of the heating network.

[0049] The hydrogen produced by the electrolysis of water in the electrolyzer 3 is stored in the hydrogen storage tank 2 and then enters the gas turbine 1 for combustion.

[0050] It should be noted that, due to the characteristics of wind power generation, there are "valley electricity" and "junk electricity", and this part of electricity is often not effectively utilized and is wasted. This part of electricity can be used to produce hydrogen in the electrolyzer 3, and the hydrogen is stored in the hydrogen storage tank 2. When appropriate, it enters the gas turbine 1 together with natural gas to be mixed with hydrogen and burned to perform work, which not only reduces the power loss of wind power generation, but also reduces the carbon dioxide concentration of the exhaust gas of the gas turbine.

[0051] Embodiment 3

[0055] The working principle of the present invention is:

[0056] When the gas unit cannot guarantee heating under special operating conditions such as long-term shutdown, FCB operating conditions, load shedding operating conditions, or when the gas unit needs to be shut down due to on-site demand during the heating season but cannot be shut down to ensure heating, and when wind power generation has "valley electricity" and "junk electricity" due to its own characteristics, this part of electricity is often not effectively utilized and is wasted, then air enters the compressor for compression, and the compressed air and natural gas burn in the combustion chamber to produce high-temperature flue gas, which enters the gas turbine 1 and expands to do work, and the exhaust gas of the gas turbine 1 enters the waste heat boiler 10 to heat the boiler feed water to form main steam with different pressure parameters, and the main steam enters the steam turbine 13 to expand and do work, and the exhaust steam of the steam turbine 13 enters the condenser 12 to form condensate, which is then pressurized by the condensate pump 11 to the waste heat boiler 10 to form a steam-water cycle, and the heat of the condenser 12 is taken away by the circulating water.

[0057] It should be noted that the present invention transforms the system, combines the electricity produced by the wind power plant near the gas unit, and builds an additional molten salt energy storage system, which can overcome the following problems: the gas unit cannot guarantee heating under special conditions such as long-term shutdown, FCB conditions, load shedding conditions, or the gas unit needs to be shut down during the heating season due to on-site demand but cannot be shut down to ensure heating. The specific operation mode of the present invention is: under the above special conditions, the gas turbine is shut down or the gas turbine load is extremely low and heating cannot be guaranteed, the wind power is passed into the electric heater of the heat tank 5 in advance to heat the molten salt, and the heated molten salt replaces the extraction steam of the steam turbine 13 to heat the primary side return water of the heat network to produce hot water for heating. In addition, due to the characteristics of wind power generation, there is "valley electricity" and "junk electricity", and this part of electricity is often not effectively utilized and is wasted. This part of electricity can be used in the electrolyzer 3 to produce hydrogen, and the hydrogen is stored in the hydrogen storage tank 2. When appropriate, it enters the gas turbine 1 together with natural gas to be mixed with hydrogen and burned to perform work, which not only reduces the power loss of wind power generation, but also reduces the carbon dioxide concentration of the exhaust gas of the gas turbine.
