Abstract

The invention belongs to the technical field of wind power generation, particularly relates to a power conversion and control device of a wind power generation system, and aims to solve the problems of power generation system paralysis and poor heat dissipation effect caused by overheat in a box due to power change of an existing wind power generation system and overhigh heat in a control box. According to the scheme, the device comprises a water storage tank; and a control box is fixed to the outer wall of the top of the water storage tank through bolts, a controller body is fixed to the inner wall of one side of the control box through bolts, the outer wall of the controller body is sleeved with a heat exchange pipe, a booster pump is fixed to the outer wall of one side of the control box through bolts, and the input end of the booster pump is sleeved with a water inlet pipe. Heat emitted by the controller body can be absorbed through the heat exchange pipe, cooling water in the heat exchange pipe returns to the water storage tank again through the water outlet pipe, the air suction pump is started, the heat emitted by the controller body can be sucked out through the air suction hopper, and therefore the heat dissipation effect of the device can be further enhanced.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a power conversion and control device for a wind power generation system. Background technique [0002] Wind power refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source. It has been used by people for a long time, mainly through windmills to pump water and grind flour. People are interested in how to use wind to generate electricity. Wind is one of the energy sources without pollution. And it is inexhaustible and inexhaustible. For coastal islands, grasslands, pastoral areas, mountainous and plateau areas that are short of water, fuel and inconvenient transportation, it is very suitable and promising to use wind power according to local conditions. An important force for upgrading is an important measure to promote the adjustment of energy structure. my country is rich in offshor...
