Solar energy high temperature storage type thermal power generation method and device

Abstract

The invention provides a solar energy high temperature storage type thermal power generation method and device. The solar energy high temperature storage type thermal power generation device comprises a solar energy tower thermal collection module I, a high temperature phase change thermal storage module II, a thermoelectric conversion module III and a photovoltaic power generation module IV. A solar energy photovoltaic power generation system directly changes the solar energy to electrical energy; a solar thermal power generation absorbs the solar energy through the solar energy tower thermal collection module I under the enough sunshine, the absorbed solar energy passes through the heat transferring media in the form of heat, one part of the solar energy is transmitted to the phase change thermal storage module II, the heat storage material of the phase change thermal storage module II is heated to perform phase change so as to store the heat, the other part the solar energy passes through the thermoelectric conversion module III to directly change the heat energy to the electrical energy; when the sunshine is not enough, the heat storage material releases heat to be as the heat source of the thermoelectric conversion module III. The power generation method of the invention used as a new energy and renewable energy development technology with huge development potentiality, adopts thermal storage technology to ensure effective use and provide time delay so as to transform a part of peak loads of the day to valley loads of the night.

Description

technical field [0001] The invention relates to a solar power generation device. Background technique [0002] In the past century, the development and utilization of fossil energy such as coal, oil, and natural gas has opened the prelude to the era of large industries, and the total annual energy supply of mankind has increased by nearly 10 times. However, unrestrained resource development and inefficient energy utilization have resulted in a large amount of waste of resources, increasingly serious ecological environment pollution and shortage of energy resources, and the living space of human beings has been greatly threatened. In the new century, energy science We have to face the triple pressure of resource waste, resource shortage and environmental pollution at the same time. Therefore, people gradually turn their attention to the utilization of renewable resources, power peak regulation and electric heat storage. In my country's power generation system, there is a hug...
