The wind-solar complementary heat and electricity collection, storage, supply and multistage utilization combination system comprises an area I and an area II, wherein the area I comprises a solar water heater heat collection system, a phase-change heat accumulator heat storage system, a heat storage and heating system of a multifunctional heat storage and heating water tank, a daily bathing hot water supply system, a user winter heating system and a daily drinking hot water supply system which are connected with one another; and the area II comprises a low-temperature low-pressure steam power generation system, a wind-solar complementary power generation system, a power supply system of the multifunctional heat storage and heating water tank, a user air conditioner and refrigerator refrigeration power supply system, a user lighting power supply system and an intelligent control system for phase-change heat storage and water tank heat storage and heating, which are connected with one another. The combination system has the advantages that all-weather and multi-stage storage and utilization of heat energy are achieved, the power source is diverse in sources, various devices have complementary advantages in function and heat and electricity are centrally distributed according to different seasons.

Description

technical field [0001] The invention belongs to the application field of new energy, and in particular relates to a combination system of wind and solar complementary heat and electricity collection, storage, supply and multi-stage utilization. Background technique [0002] Today's energy situation is urgent. The exploitation and utilization of fossil fuels not only bring serious environmental pollution and ecological system damage, but also lead to the depletion of fossil fuels themselves. Therefore, the research and utilization of new energy sources is imminent. In recent years, countries all over the world have invested a lot of manpower and material resources in the field of new energy research and utilization, and achieved fruitful results. [0003] The new energy sources that have been researched more and are widely used are mainly wind energy and solar energy. Wind energy and solar power generation are expected to become the most important new energy sources in the 21...
