Description

Technical Field

[0001] The present invention relates to the technical field of power generation systems, and particularly to a comprehensive energy storage power generation system. Background Art

[0002] With the rapid development of China's power grid, the power generation forms of domestic power grid power sources have also become more diverse. In recent years, with the leapfrog development of new energy power generation and water resource power generation forms, the proportion of new energy power generation in the power grid has gradually increased, and in some areas, the installed capacity of new energy is close to or exceeds that of thermal power. The power generation form has become more energy-saving and environmentally friendly, and the requirements for the capacity of the system energy storage equipment have also been further improved.

[0003] However, the power grid has the following problems to be solved urgently: 1. The impacts of new energy power generation on the safety and reliability of the power grid deserve our attention and research. The power grid users in China are a combination of industrial electricity, civil electricity, and agricultural electricity, and the difference between the peak, flat, and valley of electricity consumption is relatively large. This is a unique phenomenon of China's power grid, which requires China's power grid to have sufficient spinning reserve capacity or energy storage power sources to ensure its safety, reliability, and stability; 2. The existing power grid energy storage is still a shortcoming of the current power grid architecture. The energy storage currently adopted mainly includes: pumped storage, mechanical flywheel energy storage, and chemical battery energy storage. However, they also have certain disadvantages, specifically as follows: (1) Chemical battery energy storage: There are non-negligible problems in terms of safety, environmental protection, and waste treatment. In particular, in recent years, accidents such as energy storage battery explosions have occurred continuously, exposing certain safety hazards in chemical battery energy storage; (2) Pumped storage and mechanical flywheel energy storage: ① Poor economy. From the current situation analysis of pumped storage, currently, for every 4 kwh of electric energy consumed by the pumped storage system, it can provide a maximum of 3 - 3.2 kwh of electric energy to the power grid, with relatively low economy; there are also energy conversion consumption problems in flywheel mechanical energy storage; ② Site selection problem. Pumped storage is affected by the geographical environment, and it is relatively difficult to select a site for the power station. Currently, it mostly depends on the mountainous terrain with rivers for site selection; ③ Noise pollution. There is a noise pollution problem around the pumped storage power generation. When discharging water for power generation, the noise exceeds 70 decibels within a range of 100m near the drainage outlet, causing certain noise pollution; ④ Resource waste. In order to ensure the safe and stable operation of the power grid, there are a large number of phenomena of abandoned wind and abandoned light in the power grid every year, reducing the utilization rate of new energy power generation equipment and causing waste of power generation resources.

[0037] Working principle: When selecting a location near the cold source of the power plant and relying on the waste heat of thermal power generation, in the integrated energy storage power generation system of the present invention, a circulating water return heating furnace is added. The passage of the atmosphere is: atmosphere → third air duct corridor → circulating water return heating furnace → first air duct corridor → solar heat storage furnace → second air duct corridor → chimney.

[0038] Technical principle: (1) The specific heat of water is 4.2×10³ J / (kg·°C). Water has the advantages of good stability, large specific heat, no environmental pollution, and low price cost. Therefore, the present invention uses water as the energy storage working medium; the specific heat capacity of air is 1×10³ J / (kg·K) under standard atmospheric pressure, and the thermal expansion coefficient of air is relatively large under normal temperature and pressure. Therefore, the present invention uses air as the power generation working medium.

[0039] (2) This patent absorbs light energy, the heat energy converted from the excess electric energy of the power grid, waste heat energy, etc. of water, and utilizes the characteristic that the specific heat capacity of water is relatively large to convert and store it in the form of heat energy. When the power grid is short of electricity or the load is tense, water releases heat to the temperature difference between the air in the system, and the air in the system generates temperature and density differences at two ambient temperatures, generating wind energy. By utilizing the wind tunnel corridor effect to increase the wind speed and improve the wind power kinetic energy, a wind tunnel corridor is set up in two spaces with different temperature environments, and a wind turbine is set up in the wind tunnel corridor to realize wind power generation. According to the data obtained from experimental tests, under the standard atmospheric pressure environment, when the temperature difference ≥ 15 °C, a tapered wind tunnel is selected and calculated to achieve an air flow velocity of 3.5 - 9 m / s.

[0040] (3) Both water and air are pollution-free media. At the same time, converting and storing solar energy, waste heat, etc. into heat energy can reduce the disadvantages of other energy storage methods such as being unsafe, uneconomical, and not environmentally friendly, and it is an energy-saving and environmentally friendly power generation and storage mode.

[0041] (4) This system can not only be used as a local heating heat source, but also be arranged near thermal power plants and heating stations, so that the waste heat and waste heat of thermal power plants can be fully utilized for comprehensive power generation, heating, and energy storage, improving the comprehensive energy utilization rate. The present invention can achieve three conversion methods: light energy ←→ heat energy ←→ wind energy ←→ electric energy; light energy ←→ heat energy; electric energy ←→ heat energy, so as to achieve a power generation and energy storage mode for comprehensive energy utilization of power generation, heating, and energy storage.

[0042] (5) On the other hand, the present invention can be used as an urban and rural heating heat source, and heat exchange is carried out between the supply and return water of the primary heating pipeline network and the hot water inside the low-position heat exchange water tank and the high-position heat exchange water tank to realize the mutual conversion of the excess electric energy of the power grid ←→ heat energy, light energy ←→ heat energy, and achieve the function of energy-saving and environmental protection energy storage.
