technical field [0001] The present invention relates to a heat supply system and method, in particular to a heat supply system and method with wind-solar complementary direct drive. Background technique [0002] Wind power plays an important role in my country's energy supply. Since wind power uses natural wind as the driving force, the wind power generation system presents the characteristics of intermittent, fluctuating and non-periodic. The instability of natural wind will affect the stability of the power grid and power quality, resulting in a series of technical problems such as unbalanced system energy supply, voltage fluctuations and flicker, and system frequency deviation. Solar heating is a technology that uses solar collectors to collect solar radiation and convert it into thermal energy for heating. Similarly, solar energy is also unstable, and it is greatly affected by the weather, which leads to the instability of solar heating. . [0003] Today, with the cont...

Problems solved by technology

The instability of natural wind will affect the stability and power quality of the power grid, causing a series of technical problems such as unbalanced energy supply of the system, voltage fluctuation and flicker, and system frequency deviation.

Solar heating is a technology that uses solar collectors to collect solar radiation and convert it into thermal energy for heating. Similarly, solar energy is also unstable, and it is greatly affected by the weather, which leads to the instability of solar heating.

[0003] Today, with the continuous development of industrial production, the demand for high-temperature heat in industrial production is also increasing rapidly. However, in the existing technology, only wind or solar energy is used for heating without heat pumps, and the wind and solar resources per unit area are not fully utilized. , In addition, when producing high-temperature heat, relying on a single compression heat pump system for heating, the thermal efficiency is low, the economy is poor, and it is difficult to meet the production demand; It is necessary to provide a wind-solar complementary direct-driven heating system and method, using wind energy and solar energy complementary heating, making full use of inter-regional wind and solar resources, and obtaining high-temperature heat with large parameters and large capacity to meet the high-temperature heat of industrial production. need
