Abstract

The invention discloses an operation optimization decision-making method for a gas-steam combined cycle unit, and belongs to the technical field of gas turbines. The operation optimization decision-making method for the gas-steam combined cycle unit comprises the following steps: step 1, mining and processing data in a distributed control system of the gas-steam combined cycle unit, and summarizing effective operation data; step 2, decomposing layer by layer based on a calculation relationship and a mechanism relationship of the operation parameters of the gas-steam combined cycle unit, and carrying out classification processing on the effective data; step 3, combining the classified effective data, and carrying out calculation processing by utilizing a performance calculation principle and a consumption difference analysis principle; step 4, drawing the optimal operation mode graph or curve graph according to a calculation result; and step 5, feeding back to an operation center through an information network to assist the unit to optimize operation. According to the invention, the performance state of the unit is monitored in real time, the optimal operation curve is sought through the performance and consumption difference analysis and calculation, and the safe and efficient operation of the unit is guaranteed.

Description

technical field [0001] The invention relates to an operation optimization decision-making method of a gas-steam combined cycle unit, belonging to the technical field of gas turbines. Background technique [0002] The gas-steam combined cycle unit undertakes various tasks such as power grid peak regulation, heating and cooling of the heating network. Operate efficiently and economically. In addition, for the unit operators, it is necessary to grasp the performance status of the main engine, auxiliary machines and auxiliary systems in the unit in real time, so as to optimize the operation mode in time. [0003] At present, the optimization of gas-steam combined cycle units usually only involves simple performance test calculations. It takes a lot of time and preparation work to complete the field test, analyze the operating status and indicators of the unit through the test data, and only focus on the test performance of the unit. It has the significance of real-time monitor...
