Abstract

The invention relates to the technical field of wind power utilization, in particular to a wind and electricity compensatory wind energy comprehensively-utilizing system. The wind and electricity compensatory wind energy comprehensively-utilizing system comprises a wind power mechanical energy converting device, an electric driving device, a double-power synthesizing device, a power loading device and a controlling system. The wind and electricity compensatory wind energy comprehensively-utilizing system is characterized in that the double-power synthesizing device comprises a first input shaft, a second input shaft and a power output shaft. The wind power mechanical energy converting device comprises a wind turbine and a wind power output shaft, and the wind power output shaft is connected with the first input shaft. The electric driving device comprises a motor connected with the second input shaft. The invention further discloses a control method. The wind and electricity compensatory wind energy comprehensively-utilizing system has the advantages that the wind energy and the electric energy can be synthesized in an overlapping mode, the application limitation caused by randomness and uncertainty of the wind energy can be effectively broken through, and when the wind energy exceeds the demand of the power loading device, the controlling system can convert the surplus wind energy into the electric energy and feed the electric energy back to a power grid, and the wind energy is efficiently utilized.

Description

technical field [0001] The invention relates to the technical field of wind power utilization, in particular to a wind power complementary wind energy comprehensive utilization system, and also relates to a control method of the system. Background technique [0002] Wind energy is a clean, safe, and renewable green energy. The use of wind energy has no pollution to the environment, no damage to the ecology, good environmental and ecological benefits, and is of great significance to the sustainable development of human society. The use of wind energy is mainly in two forms: wind energy as power and wind power generation; wind power generation is to convert the kinetic energy of the wind into mechanical energy, and then convert the mechanical energy into electrical energy, and there will be a large conversion loss in energy conversion. Using wind energy as power is to use wind to directly drive various mechanical devices, such as driving water pumps to lift water, driving high...

AI Technical Summary

Problems solved by technology

When the above existing technologies are combined, there are still the following defects; one is that when the wind force is too large, the traditional method is to use a damping device to consume excess wind energy, which also causes another waste of energy, and the change cannot be changed randomly. The huge wind force is fully utilized, and the second is that the above-mentioned power balance output system cannot synthesize the torque generated by wind force and electric power; The formed wind energy utilization system with stable power output will make the utilization prospect of wind energy more broad
