Problems solved by technology

At present, most of the distributed energy supply systems in China are powered by a single energy source, resulting in low overall energy utilization rate of the system and low benefits. The low energy utilization rate lacks energy storage modules during operation, which is difficult Avoid energy duplication, energy waste, environmental pollution and other disadvantages
If the joint energy supply of multiple energy sources is used directly, a large amount of energy will be consumed, and if the energy storage system is added separately, the energy utilization rate cannot be guaranteed on the one hand, and on the other hand, the use of the distributed energy supply system will be limited and cannot meet the basic supply and demand of users.

The active and passive type energy source and phase-change energy storage coupled power supply system comprises an active type energy source power supply system, a residual heat boiler, a passive type energy source power supply system and a phase-change energy storage device, wherein the active type energy source power supply system is used for providing electric energy for power generation equipment and supplying the electric energy to power utilization equipment; the residual heat boiler is used for carrying out residual heat recycling on high-temperature flue gas generated by the active type energy source power supply system and storing recycled energy in the phase-change energy storage device; and the phase-change energy storage device is used for carrying out afterburning on the passive type energy source power supply system and providing domestic water to the outside. According to the power supply system provided by the invention, the consumption of active type energy sources is reduced by utilizing the active type energy source power supply system, a phase-change energy storage system and the passive type energy source power supply system and seamless connection of the three systems is realized; the energy source utilization rate of the system is improved, wastes of a plurality of types of energy sources are reduced and the disadvantages that the utilization rateof the system is low and the system is not stable and the like are overcome; and the system has relatively high popularization value.

Description

technical field [0001] The invention relates to the technical field of energy utilization, in particular to an active and passive energy source coupled with phase change energy storage energy supply system. Background technique [0002] Nowadays, China is one of the largest energy consumers in the world. Although the total amount of resources and energy is large, due to the large population base, the main energy resource reserves are at a relatively low level compared with the world. At present, most of the distributed energy supply systems in China are powered by a single energy source, resulting in low overall energy utilization rate of the system and low benefits. The low energy utilization rate lacks energy storage modules during operation, which is difficult Avoid the disadvantages of energy duplication, energy waste, and environmental pollution. If the joint energy supply of multiple energy sources is directly used, a large amount of energy will be consumed, and if th...
