Abstract

The invention discloses a performance index correcting and comparing method for a combined cycle generating unit. The performance index correcting and comparing method comprises the following steps: 1), calculating the integral power, heat consumption rate and gas consumption rate of the combined cycle generating unit under the current atmospheric environment and an operation mode according to measurement data in a real-time database; 2), acquiring measurement data relevant with a performance correction calculation factor and calculating the relevant performance index correction calculation factor; 3), correcting various performance indexes in the step 1 and obtaining a corrected and calculated performance index of a standard ISO (International Standard Organization) working condition; and 4), comparing performance index data of the standard ISO working condition with traditional corrected and calculated performance index data of the standard ISO working condition of the unit or other units and outputting a corresponding operation regulating control instruction by an operator according to the evaluation result. The invention further discloses a regulation control system based on the performance index correcting and comparing method of the combined cycle generating unit. According to the performance index correcting and comparing method provided by the invention, the unit operation can be optimized and the economy and the safety are improved.

Description

technical field [0001] The present invention relates to the performance index correction and evaluation of the combined cycle generating set and the adjustment and control method of the unit, as well as the system for realizing the performance index correction, evaluation and the conclusion obtained from the evaluation to better adjust and control the generating set, especially in different atmospheric environments 1. Performance index correction and performance evaluation comparison methods of gas-steam combined cycle generator sets under different operating modes. Background technique [0002] Gas-steam combined cycle power generation has high thermal efficiency of the overall cycle, low environmental pollution, low unit investment under the same conditions, good peak-shaving performance, quick start and stop, small land occupation, low water consumption, short construction period and can be put into production in stages, and the degree of automation The characteristics of...
