Scheduling method, server and system of combined heat and power generation system of fire coal thermal power plant

Abstract

The application provides a scheduling method, a scheduling server and a scheduling system of a combined heat and power generation system of a fire coal thermal power plant. The scheduling method of the combined heat and power generation system of the fire coal thermal power plant is deployed on the scheduling application server in the scheduling system of the combined heat and power generation system of the fire coal thermal power plant, and includes: obtaining initial data needed by building working condition models of all devices in the combined heat and power generation system from a synthetic data integration platform, and building the working condition models of all the devices in the combined heat and power generation system according to the initial data; judging whether preset scheduling conditions are met or not, and if yes, confirming a scheduling policy of the combined heat and power generation system of the fire coal thermal power plant under a current load according to real-time power and heat load data output by the working condition models, and controllable variables and auxiliary variables, which influence outputting of the working condition models. According to the scheduling method, the scheduling server and the scheduling system of the combined heat and power generation system of the fire coal thermal power plant, scheduling problems are considered by integrating blending coal, a boiler, a turbine generator and a temperature and pressure reducer together, and a scheduling scheme can be globally optimized.

Description

technical field [0001] The present application relates to the field of information technology, in particular to a scheduling method, server and system for a cogeneration system of a coal-fired thermal power plant. Background technique [0002] With the development of science and technology, electricity occupies a particularly important position in people's lives. Generally, power plants only produce electricity to supply power to users, while industrial production and domestic heat (steam) are supplied separately by other industrial boilers and heating boilers. This production method is called heat and electricity division. In thermal power plants, heating units are used. In addition to supplying electric energy, steam turbines that have done work (that is, power generation) are used to extract steam or exhaust steam to meet the heat required for production and life. This production method is called Cogeneration. [0003] The structure diagram of a typical cogeneration sys...
