Wind power plant computer monitoring system based on novel wind generator

Abstract

The invention discloses a wind power plant computer monitoring system based on a novel wind generator. The wind power plant computer monitoring system comprises a wind power generation module, a monitoring module and a control module, the wind power generation module converts input mechanical energy into electric energy by utilizing wind energy, the monitoring module is connected with the wind power generation module and monitors the wind power generation module, and the control module is connected with the wind power generation module and the monitoring module, receives signals transmitted by the monitoring module and controls the wind power generation module. According to the wind power plant computer monitoring system, the transmission ratio of a speed change unit can be adjusted, when wind power is small, the transmission ratio is reduced, the generator can be driven to rotate, when the wind power is large, the transmission ratio is increased, the rotating speed of blades is reduced, meanwhile, the power generation amount is increased, the blades are protected, the power generation amount is increased; and the service life of a braking device is prolonged.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind farm computer monitoring system based on a novel wind generator. Background technique [0002] Wind energy resources are determined by the wind energy density and the annual cumulative hours of available wind energy. The World Meteorological Organization estimates that the global wind energy is about 2.74×109MW, of which the available wind energy is 2×107MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth, equivalent to the energy produced by 1.08 trillion tons of standard coal , about 100 times the world's current energy consumption. Wind has been used by people for a long time, mainly through windmills to pump water, grind flour, etc., but now, people are interested in how to use wind to generate electricity. Convert the kinetic energy of the wind into mechanical kinetic energy, and then conve...

Problems solved by technology

[0004] When using wind energy, the speed of the blades of the wind turbine should not be too fast, otherwise a large centrifugal force will be generated, causing the blades to fall or break. Shaft speed, but the transmission ratio of the speed-increasing gearbox is a fixed value. In order to prevent the blade from rotating too fast when encountering strong winds and typhoons, it is usually necessary to adjust the blade pitch angle and braking device to stop the blade from rotating or use a conventional Rotate at a higher speed, but this cannot take advantage of the windy weather, resulting in a waste of resources, and the braking device is also easily damaged
