Method for wind-light mixed power generation or wind power generation

Abstract

The invention relates to a wind-solar hybrid electric generation or wind power generation method. The method is characterized in that a solar thermal current power generation system is employed; one or more than one controllable wind inlets are arranged around a heat collection covering of the solar thermal current power generation system, whether the wind inlets are opened and the opening of the wind inlets are determined according to solar energy intensity, wind direction and wind strength, if the wind inlets are required to be opened, only windward wind inlets are opened, other wind inlets are closed, and solar energy and wind energy are employed to generate electricity; when the heat collection covering in the solar thermal current power generation system is removed, the controllable wind inlets are directly arranged at a side wall of the bottom of a tower cylinder, a turbogenerating set is fixedly arranged on a current channel formed by the wind inlets and the top opening of the tower cylinder, and the generating system performs wind power generation. The method has the advantages of perfecting the solar thermal current power generation system, simultaneously employing solar energy and wind energy resources, improving the generation system into the wind-solar hybrid electric generation system, increasing electric power generation of the system, lowering the generating cost, causing the solar thermal current power generation system to have commercial promotion and operation value; and greatly reducing the cost of wind driven generators by a new wind power generating form consisting of the controllable wind inlets, the tower cylinder and a turbogenerator; and power generation systems established according to the method have extremely low operation and maintenance cost.

Description

Technical field: [0001] The invention relates to a method for wind-solar hybrid power generation or wind energy power generation. technical background: [0002] In the past 5 years, the development of wind power has continuously exceeded its expected development speed, and has maintained its position as the fastest growing energy source in the world. Since 2003, the average annual growth rate of global wind power installed capacity is 24%. By the end of 2007, the cumulative installed capacity of wind power in the world was 19,791 MW, and the total installed capacity of wind power in China reached 5,909 MW, exceeding the goal of 5,000 MW in 2010 proposed in the National Medium and Long-term Development Plan of the Renewable Energy Law three years ahead of schedule. With the support of the national "Renewable Energy Law" and other policies, the enthusiasm for developing wind power in various parts of our country is unprecedentedly high. In September 2007, the Inner Mongolia ...
