Heat consumption characteristic analysis method for main pipe thermal power plant turboset

Abstract

The invention discloses a heat consumption characteristic analysis method for a main pipe thermal power plant turboset, and belongs to the technical field of turboset heat consumption characteristics.The method aims at solving the technical problems that in the prior art, the operation condition of a main pipe thermal power plant is complex, instrument measuring points are incomplete, and real-time monitoring and thermal economy evaluation of a unit are difficult. The method includes: dividing operation mode of a turboset of the main pipe thermal power plant into operation without a deaeratorand operation with the deaerator; respectively establishing a heat consumption model of the running unit without the deaerator and a heat consumption model of the running unit with the deaerator; collecting measuring point data of a main pipe thermal power plant turboset; and analyzing the heat consumption characteristics of the main pipe thermal power plant in different operation modes based onthe collected measuring point data and the established heat consumption model. According to the method, the heat consumption models are respectively established by dividing the unit into a deaerator-free operation mode and a deaerator-containing operation mode, so that the thermal economy of the unit can be analyzed only through a small amount of measuring point data, and the operation condition of the unit can be conveniently monitored on line.

Description
