Problems solved by technology

[0003] Real-time changes in calorific value will lead to frequent fluctuations in unit load. During this process, the main steam temperature will fluctuate greatly, often requiring manual intervention by operators to ensure continuous and normal operation of the production process. However, the control system in related technologies has already Unable to meet the requirements of automatic control

Abstract

The invention relates to the technical field of temperature control, in particular to a main steam temperature control method which comprises the steps that main steam preset temperature information is acquired; acquiring controlled variable information of main steam; disturbance variable information of main steam is obtained; acquiring main steam real-time temperature information according to the controlled variable information and the disturbance variable information; the main steam preset temperature information is compared with the main steam real-time temperature information; if the temperature difference is smaller than a preset threshold value, no-action information is output; if the temperature difference is larger than or equal to the preset threshold value, operation variable information is output to control the main steam temperature. The method has the effects of reducing the frequency of manual intervention and meeting the automatic control requirement of the main steam temperature.

Description

technical field [0001] The present application relates to the technical field of temperature control, in particular to a method, system and electronic equipment for controlling the temperature of main steam. Background technique [0002] The main steam temperature is one of the important parameters to ensure the safe and economical operation of the unit in large thermal power plants. If the main steam temperature is too high, it will directly affect the safe operation of superheater pipes, steam turbines and other equipment; if the main steam temperature is too low, it will affect the thermal efficiency of the unit. Therefore, effective and reasonable control of the main steam temperature is an important task in the production and operation of power plants. [0003] Real-time changes in calorific value will lead to frequent fluctuations in unit load. During this process, the main steam temperature will fluctuate greatly, often requiring manual intervention by operators to e...
