Wind power generation and power supply system based on grid power complementation

Abstract

The invention provides a wind power generation and power supply system based on grid power complementation. The system is characterized by comprising four parts, wherein the first part comprises four paths for supplying power to an AC load; the second part comprises four paths for supplying power to a DC load; the third part comprises two paths for supplying power to a device power supply bus in a 220V system; and the fourth part comprises a voltage, current, electric quantity, phase position, wind speed, temperature and humidity detection circuit, a system display unit and a remote transmission module. The system provided by the invention organically integrates electric energy output by a fan and electric energy output by a power grid, is used for supplying ceaseless three-phase AC power and high-voltage DC power to various loads and has a man-machine interaction function and a data remote-transmission function.

Description

technical field [0001] The invention relates to a wind power power supply system based on the complementarity of grid and electricity, which controls the switching of wind power and grid power according to the voltage and current value detected by each part of the detection circuit, and specifically relates to the fields of detection technology, power electronics technology, embedded control, and data communication. Background technique [0002] With the continuous deterioration of environmental pollution and the continuous consumption of non-renewable energy, clean energy such as wind energy has received extensive attention. Wind energy is mainly used to drive wind turbines to rotate and output electric energy. Oscillation of electric energy amplitude and discontinuity of output electric energy. Chinese invention patent application number: 201310297683.7 titled "Off-grid wind power supply system based on grid-power complementarity" is a "one-to-many" off-grid power supply s...

Problems solved by technology

[0003] With the current technological development, small power loads can be uninterruptedly powered by a combination of wind turbines and batteries, but some high-power equipment still needs to use the grid for uninterrupted power supply, and now there is no equipment that can use wind resources when the wind is sufficient. Power supply for high-power loads, and automatically switch grid power to supply power for high-power loads when there is no wind
