Acquisition method for optimum washing period of compressor

Abstract

The invention discloses an acquisition method for an optimum washing period of a compressor. The method comprises the following steps: detecting the operating time of a gas turbine after washing; calculating the rated power of the gas turbine after washing and detecting the actual power of the gas turbine after washing; acquiring the average performance deterioration rate of the gas turbine according to the operating time of the operating time of the gas turbine after washing, the rated power of the gas turbine after washing and the actual power of the gas turbine after washing; and acquiringthe optimum washing period of the compressor according to the average performance deterioration rate of the gas turbine. The acquisition method can acquire the optimum washing period of the compressorby calculating the average performance deterioration rate of the gas turbine, and washing is carried out from the economical aspect, so that the operating cost of a power plant is saved.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a method for obtaining an optimal water washing cycle of a compressor. Background technique [0002] At present, some gas turbine equipment manufacturers have not given a clear reference value for the off-line water washing cycle of the compressor. Currently, the gas turbine output is reduced by 5%-10% for water washing as a standard, and there is also a fixed time for the gas turbine to run after water washing As a standard, the former needs to correct the power of the gas turbine, but the power correction is a complicated process, and the unit is required to operate at full load, but the gas turbine unit often operates under partial load according to the scheduling requirements. It is often difficult and unrealistic. The latter is greatly affected by the condition of the compressor due to the condition of the region, environment, season, etc., and the fixed washing cyc...

[0002] At present, some gas turbine equipment manufacturers have not given a clear reference value for the off-line water washing cycle of the compressor. The existing gas turbine output is reduced by 5%-10% for water washing as a standard, and there is also a fixed time for the gas turbine to run after water washing As a standard, the former needs to correct the power of the gas turbine, but the power correction is a complicated process, and the unit is required to operate at full load, but the gas turbine unit often operates under partial load according to the scheduling requirements. It is often difficult and unrealistic. The latter is greatly affected by the condition of the compressor due to the condition of the region, environment, season, etc., and the fixed washing cycle will bring poor economic effects and increase the operating cost of the power plant.
