Embodiment Construction

[0035] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0036] like figure 1 As shown, the nuclear power peak shaving system integrated with cryogenic technology proposed by the present invention mainly includes three subsystems, namely nuclear power generation subsystem 10 , air liquefaction subsystem 20 and liquid air energy release subsystem 30 .

[0037] The nuclear power generation sub-system 10 operates at full capacity according to the rated load of the nuclear power system during the first period when the user load demand is less than the rated load of the nuclear power system, and the excess electric energy generated by it is used to drive the air liquefaction sub-system 20 to produce liquid air.

[0038] The air liquefaction subsystem 20 converts excess electric energy generated by the nuclear power generation subsystem 10 into cryogenic energy...

Abstract

A cryogenic energy storage-based nuclear power peak load regulation system comprises a nuclear electric power generation subsystem (10), an air liquefaction subsystem (20), a liquid air energy release subsystem (30) and a energy storage unit (40); during a first period that the load demand of users is less than the rated load of a nuclear power system, redundant electric energy generated by the nuclear electric power generation subsystem is converted into cryogenic energy by means of an air liquefaction process and the cryogenic energy is then stored in liquid air; during a second period that the load demand of users is more than the rated load of the nuclear power system, the energy of the liquefied air stored in the air liquefaction subsystem is converted into electric power; cold released by re-gasifying the liquid air in the liquid air energy release subsystem is stored in the cold accumulation unit in the form of sensible heat during the second period that the load demand of users is more than the rated load of the nuclear power system, and the stored cold is used for liquefying the air of the air liquefaction subsystem during the first period that the load demand of users is less than the rated load of the nuclear power system. The system can remarkably improve the power generation efficiency and net work yield of nuclear reactor heat of the nuclear power system during a peak demand period, in order to realize the purpose of peak load shifting, and furthermore, the system is high in energy storage efficiency.

Description

technical field [0001] The invention relates to the field of large-capacity (high-power, long-time) power storage and management in the electric power industry, and more specifically, to a nuclear power peak-shaving system based on cryogenic energy storage. Background technique [0002] Nuclear power generation is characterized by high system investment but low operating costs, so the cost per unit of electricity is closely related to the annual operating hours of nuclear power equipment and the average load factor. Although nuclear power generation has been based on base load for a long time in the past to ensure high-load and long-term continuous operation of nuclear power, with the continuous increase in nuclear power installed capacity, local power grids may be difficult to accommodate it in low power consumption full load output. For example, France's nuclear power installed capacity in recent years temporarily accounts for 53% of its total installed capacity, while th...
