Calculation method, device and equipment for performance test result of back pressure unit and medium

Abstract

The invention discloses a calculation method and device for a performance test result of a back pressure unit, equipment and a medium. The calculation method comprises the steps that performance test parameters of the back pressure unit are obtained; the sum of the main steam parameter, the cold resteam parameter, the superheater parameter and the reheater parameter is subtracted from the heat load of the condenser, and then the difference is divided by the generator parameter to obtain the heat consumption rate of the back pressure unit; calculating the working range of the heat consumption rate of the back pressure unit according to the mechanical efficiency and the generator efficiency in the back pressure unit; whether the heat consumption rate of the back pressure unit is within the working range of the heat consumption rate of the back pressure unit or not is judged; and when the heat consumption rate of the back pressure unit is within the working range of the heat consumption rate of the back pressure unit, outputting the obtained heat consumption rate of the back pressure unit as a corrected performance test result of the back pressure unit. According to the method, a relatively real and accurate calculation result can be obtained, and a reliable basis is provided for economic index evaluation of the back pressure unit.

Description

technical field [0001] The invention relates to the technical field of performance test of a back pressure unit, in particular to a calculation method, device, equipment and medium for the performance test result of a back pressure unit. Background technique [0002] When the performance test of the back pressure unit is carried out, the test standard does not clearly stipulate the correction method for the calculated test heat consumption rate and the actual generator output, that is, the generator active power. It is not correct to calculate and correct according to the method of pure condensing unit because the specific working conditions of back pressure unit and pure condensing unit are different. The prior art lacks a calculation method for the performance test results of the back pressure unit, and the performance test results can only be obtained by copying the calculation and correction methods of the pure condensing unit, and the heat consumption rate data in the t...
