A Method for Analyzing Heat Consumption Characteristics of Steam Turbine Units in Main Tube Cogeneration Power Plant

Abstract

The invention discloses a method for analyzing heat consumption characteristics of a steam turbine unit in a main control thermal power plant in the technical field of steam turbine unit heat consumption characteristics. To solve the technical problems of difficult monitoring and thermal economic evaluation, the operation mode of the steam turbine unit in the parent-controlled thermal power plant is divided into operation without deaerator and operation with deaerator; respectively establish the heat consumption model of the unit without deaerator and with The heat consumption model of the deaerator operating unit; collect the measurement point data of the steam turbine unit of the main pipe thermal power plant; analyze the heat consumption characteristics of the main pipe thermal power plant under different operating modes based on the collected measurement point data and the established heat consumption model. In the present invention, the heat consumption models are respectively established by dividing the unit into the operation without deaerator and the operation with deaerator, and only need a small amount of measuring point data to realize the analysis of the thermal economy of the unit, which is convenient for the operation of the unit The status is monitored online.
