Embodiment Construction

[0047] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0048] like figure 1 , the deep comprehensive peak regulation system of the power plant, including heating equipment and absorption chiller 4; the heating equipment is used to connect with the substation 1 through a step-down transformer, and reduce the voltage from 220KV to 10~35KV, and use electricity to generate heat The water is transported to the heating pipe network; the heating equipment includes solid heat storage equipment 3; the absorption refrigerator 4 is connected with the heating equipment, and is used to convert the heat generated by the heating equipment into cold energy and sent to the cooling network. When working, the generated heat or cold can be selected and transported to the corresponding pipe network according to the needs, which not only meets the peak shaving requirements, but also meets the heating / cooling demand.

Abstract

The invention discloses a comprehensive depth peak load regulation system for a power plant and a peak load regulation method. The comprehensive depth peak load regulation system comprises heating equipment and an absorption chiller. The heating equipment is used for being connected with a substation and capable of generating hot water through electricity and delivering the hot water into a heat supply pipe network. The heating equipment comprises solid heat storage equipment. The absorption chiller is connected with the heating equipment and used for converting heat generated by the heating equipment into cold energy and delivering the cold energy into a cooling pipe network. By the adoption of the comprehensive depth peak load regulation system for the power plant and the peak load regulation method, the purposes that heat is provided in winter, the cold energy is provided in summer, and stored energy can be used for power generation during non-heating or non-cooling seasons can be achieved, the year-round depth peak load regulation is achieved, the equipment utilization rate is increased greatly, the peak load regulation effect is improved greatly, and the good economic benefitscan be achieved by using the difference in electricity charges of the peak-valley power.

Description

technical field [0001] The invention relates to an in-depth integrated peak-shaving system of a power plant, and also relates to a peak-shaving method, which is used in wind power plants, thermal power plants, nuclear power plants and the like. Background technique [0002] Due to the reduction of load at night, the power grid needs to absorb the large capacity load of wind power generation, so as to ensure that wind power generation and photoelectricity, which are clean energy sources, are given priority to the grid. [0003] The existing deep peak shaving technology of combined heat and power plants using electric heat storage equipment has great limitations, and the adjustment space is limited, which cannot meet the requirements: firstly, it is only suitable for occasions where thermal power plants have heat demand, and secondly, it can only be used in winter heating seasons In order to start peak shaving, other measures must be taken for deep peak shaving of power plants...
