Embodiment Construction
[0018] The technical solutions of the present invention will be further described in more detail below in conjunction with specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0019] refer to figure 1 , figure 1 It is a structural schematic diagram of a distributed energy supply system for electric heat storage and thermal energy generation provided by the present invention. The distributed functional system 100 replaces the boiler of the coal-fired power generation unit through an electric heat storage and heat exchange three-in-one device 110, and is connected in series between the feed water pump 101 and the steam turbine 102; the electric heat heat storage and heat exchange three...

The invention discloses a distributed energy supply system for electric heating heat storage heat energy power generation. The complete system is formed through assembly of an electromagnetic excitation winding, a metal energy storage material, a metal shell thereof and an electric heating heat storage and heat exchange three-in-one device which is composed of a heat exchanger pipeline penetratingthrough the metal energy storage material and is used for replacing a boiler of a coal-fired power generating set. According to the system, due to the fact that an energy storage body is used for providing energy, no combustion exists in the power generation and heat supply process, and pollutant emission is avoided; meanwhile, a boiler system, a coal supply system, a wind and smoke system and the like are omitted, and the site occupation is greatly saved; and therefore, the system can be arranged close to load centers of living space, office and the like, and is shorter in energy transfer distance, low in loss, high in safety coefficient, low in rejection processing cost and extremely high in regeneration utilization rate compared with an energy source distributed in a park.
Description
technical field [0001] The invention relates to the field of electric power technology, in particular to a distributed energy supply system for electric heat storage and thermal energy power generation. Background technique [0002] The ability of the power grid to receive and absorb renewable energy largely depends on the overall structure of the power system, especially the ability of peak regulation and frequency regulation. At present, my country's power supply structure is dominated by large-scale thermal power units, especially in the "Three North" regional power grids, almost all AGC frequency-modulated power supplies are thermal power units, and high-quality frequency-regulated power supplies are scarce. In addition, the "Three Norths" are areas where my country's wind power is intensively developed, and the large-scale grid connection of wind power will significantly increase the AGC frequency modulation demand of the power grid. In particular, during the period of...
