Abstract

The invention discloses a multi-source heat supply system which belongs to the technical field of heat supply equipment and comprises a phase change energy storage tank, a constant temperature energystorage tank, a solar thermal collector and a first electric heater, wherein the phase change energy storage tank and the constant temperature energy storage tank are filled with a phase change material, and a circulation loop is formed between the phase change energy storage tank and the constant temperature energy storage tank via a first pipeline; a second pipeline is connected between a mediuminlet of the solar thermal collector and a medium outlet of the solar thermal collector, the second pipeline is filled with a working medium and a part of the second pipeline is located in the phasechange energy storage tank; and the first electric heater is disposed in the constant temperature energy storage tank. The multi-source heat supply system disclosed by the invention has the advantagesthat the system can make full use of solar energy for heat supply in the daytime and storage surplus thermal energy; and at night, the system can supply and store the thermal energy by making use ofpower generated by a generating set or off-peak electricity at night, so wind abandoning and electricity limiting of a wind generation set are avoided and the use ratio of wind energy and solar energyis increased.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to a composite source heating system. Background technique [0002] In areas with rich wind energy resources in my country, wind energy resources are abundant, and the scale of wind power installed capacity is increasing continuously to improve the utilization rate of wind energy. [0003] However, during the winter heating period, when there is a strong wind in the north, the combined heat and power unit must ensure stable operation, and the power generation load increases in a large area, making it more difficult to adjust the peak of the power grid, especially at night, which is the peak of heating and heating. In the trough stage of electricity load, and because the price of thermal power is lower than that of wind power, wind turbines have to abandon wind and limit power in large quantities, resulting in a great waste of wind energy resources.
