Problems solved by technology

Therefore, ordinary transformers are difficult to meet the needs of wind power generation, so it is urgent to develop a new transformer for wind power generation that meets the needs.
[0006] The existing wind power generation system generally only has 2 or 3 megawatts, which cannot meet the actual needs. We have developed a high-power wind power generation system; its power generation capacity is above 5 megawatts

Abstract

The invention discloses a high-power wind power generating system which comprises a wind power generator, a zero-point switching circuit, an intelligent control system, a wind power generating transformer and a power utilization network. The wind power generating transformer is arranged in the zero-point switching circuit and used for voltage transformation of power generated from the wind power generator and then connecting the power to the power utilization network. The zero-point switching circuit is arranged between the wind power generator and the power utilization network. The intelligent control system is used for controlling the wind power generator to generate power according to control parameters. The wind power generator comprises an intelligent fuzzy controller, a PID(proportion, integration and differentiation) hydraulic valve, an air valve, a wind power sensor and a rotational speed sensor, the wind power sensor is connected with the intelligent fuzzy controller, the rotational speed sensor detects rotational speed of a generator rotor and connected with the intelligent fuzzy controller, and the intelligent fuzzy controller controls the PID hydraulic valve to regulate the air valve by analyzing data transmitted from the wind power sensor and the rotational speed sensor. The high-power wind power generating system can be connected to a power grid as a thermal power generation system, and is adaptable to severe environments.

Description

technical field [0001] The invention relates to a power generation system, especially a high-power wind power generation system, and belongs to the technical field of wind power generation equipment. Background technique [0002] With the development of society, people's demand for energy is increasing, and water energy has been basically exploited by people; while oil, coal and other resources are non-renewable resources, a little less is used. It is estimated that after 100 years, oil, coal, etc. And other resources will be exhausted, and the burning of oil, coal and other resources will pollute the environment; therefore, in recent years, people have begun to look for new renewable energy, wind energy is a very good renewable energy, and it is non-polluting. Wind power generation is driven by the wind to drive generators to generate electricity; the frequency and voltage of the generators are unstable due to the instability of the wind force. As a clean energy source, the...
