System for realizing participation in deep peak regulation through matching of electric heating boiler with indirect air cooling unit

Abstract

The invention relates to the technical field of power equipment, in particular to a system for realizing participation in deep peak regulation through matching of an electric heating boiler with an indirect air cooling unit. The system comprises an air cooler, a condensate pipe of the air cooler communicates into a low-pressure heater and a heat exchanger through a shunt three-way valve, the outlet end of a water outlet pipe of the low-pressure heater communicates into the heat exchanger through a confluence three-way valve, the outlet end of the confluence three-way valve is connected with awater supplementing pipe, and one side of the heat exchanger is connected with the electric heating boiler. According to the design, work of partial or all low-pressure heaters can be replaced in thepeak regulation period, the boiler load can be in the lowest stable combustion load state, the load of a power generation system can be further reduced when the load of a generator set cannot be further reduced to participate in deep peak regulation, the peak regulation effect is improved, the online load of the generator set is reduced, the clean energy consumption is promoted, the steam consumption is reduced, the total coal consumption of a power plant is reduced, and energy waste is reduced.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a system that uses an electric heating boiler to cooperate with an indirect air-cooling unit to realize deep peak regulation. Background technique [0002] Due to the sharp increase in electricity consumption in my country, the original power operation mode is no longer suitable, and various new energy sources are constantly being added to power generation energy. The peak shaving is to make the main grid run in a reasonable range and control the energy consumption within a reasonable amount through the timely regulation of the generating units (mainly thermal power units). In order to improve the new energy consumption capacity in Xinjiang, especially to alleviate the difficulty of peak regulation, the utilization hours of domestic thermal power plants have been decreasing year by year, and the load has been reduced year by year. ability. In the prior art, the...

Problems solved by technology

However, the pure boiler peak-shaving technology has limited effect during use, and cannot well reduce the grid-connected load of the generator set. The ability to absorb clean energy is effective, resulting in energy waste.
