Description

An Energy Complementary Self-Power Supply System

technical field

The utility model relates to the technical field of power generation equipment, in particular to an energy complementary self-power supply system suitable for independent areas such as manors and islands.

Background technique

At present, the traditional power supply method is the electric energy generated by centralized large-scale power plants (such as thermal power plants, hydropower plants, and nuclear power plants), and supplies power to users through long-distance multi-level transmission of the power system. However, areas that are difficult to cover with conventional power grids, such as It is difficult for users in independent areas such as islands and manors to use traditional power supply methods, so the demand for self-powered systems in these areas is increasing. In the prior art, different methods can be used for power generation in self-powered systems, such as solar power, wind power, diesel generators, and the like. However, the scheme of only relying on wind or solar power generation is greatly affected by the intensity of the sun and wind, and it is difficult to achieve continuous work under different environmental conditions. However, the scheme of using traditional diesel generators for power generation has high power generation costs and the exhaust gas pollutes the air. Higher, not conducive to energy saving and emission reduction.

With the development of technology, the power supply system of multi-energy complementary power generation has gradually developed. For example, (1) Chinese invention patent application 201010553641.1 discloses an independent power supply system using multiple energy sources for complementary power generation, which realizes the complementary power generation of wind power generators, solar photovoltaic panels and diesel generators. Although the power supply system can achieve different Using a variety of renewable resources for continuous power supply under environmental conditions, but still relying on diesel generators for power generation; (2) Chinese invention patent application 201210336607.8 discloses a multi-clean energy complementary micro power station, including battery packs, inverters, multiple Fuel engines, generators, wind power generators, hydroelectric generators and solar panels, this invention patent uses the energy storage of batteries to achieve continuous power supply, but the batteries only play a buffer role. If it is not enough, it will be difficult to achieve continuous and stable power supply; (3) Chinese invention patent 200910065233.9 discloses a solar-biomass-hydrogen coupled complementary power generation method. In solar time, biomass energy is used to generate electricity alone. During the power generation process, methanol is synthesized, and then enters the solar heater for heating, decomposes into _H2 and CO, enters the biomass gas generator to generate electricity and releases high-temperature waste gas, and the high-temperature waste gas enters the waste heat boiler. , so that water vapor is generated in the boiler, thereby driving the generator to rotate at a high speed to generate electricity. However, in the power generation process of this power generation method, the synthesized methanol still needs to be heated and decomposed into _H2 and CO by a solar heater before it can enter the biomass Gas generators generate electricity, so they are greatly restricted by solar energy. At the same time, it is difficult to control the power generation of biomass gas generators. It is even more difficult to control the use of high-temperature exhaust gas to make boilers generate water vapor and then drive generators to generate electricity, and the stability is very poor. .
