Abstract

The invention particularly relates to a wind energy and groove-type solar all-in-one power generating system which aims to solve the problems that due to the fact that all wind energy is converted into heat energy, energy waste is caused, the cost of an energy storage device is increased, and waste of wind electricity is caused in the prior art. According to the wind energy and groove-type solar all-in-one power generating system, wind energy and solar energy serve as electricity generation sources of the wind energy and groove-type solar all-in-one power generating system, unstable high-frequency electricity energy of wind electricity is converted into heat energy to be stored through a heating device, the wind electricity and solar energy heat generation electricity are united and stably output through power generation adjustment of a turbine, and therefore requirements of a power grid are met. A groove-type solar energy collector is used for collecting solar energy, a heat collection working medium is heated to reach a certain temperature, and heat energy is transferred to a working medium which acts in a cyclic mode in a power loop through a preheater, a vapor generator and a superheating reheater, or high-temperature high-pressure superheated steam is generated to drives the turbine and then drive a generator to generate electricity. The wind energy and groove-type solar all-in-one power generating system is suitable for the power field.

Description

technical field [0001] The invention relates to a power generation system, in particular to an integrated power generation system of wind energy and trough solar energy. Background technique [0002] With the maturity of wind energy and solar power generation technology, the large-scale development and utilization of wind energy and solar energy has become a necessary strategic measure for the development and utilization of new energy in my country. At present, the wind energy and solar energy complementary combined power generation technology adopted at home and abroad is mainly the wind photovoltaic complementary power generation technology. The complementary characteristics of the system are conducive to reducing the unit investment of the electric field transformation and distribution system and electric field public facilities, and ensuring the safe and stable operation of the power grid. Disadvantages of current wind-solar hybrid power generation technology: [0003]...
