Abstract

The invention discloses a multivariate function real-time optimization method, system and medium for the sliding pressure operation curve of a thermal power generating set. value with respect to the unary function curve of the basic operating parameters, and deduce the specific calculation formula of the binary function of the sliding pressure setting value when the current operating parameters are considered through the graphing method; for each operating parameter except the basic operating parameters, this will be considered When operating parameters, the specific calculation formula of the binary function of the sliding pressure setting value is summed to obtain the calculation formula of the multivariate function of the sliding pressure setting value. The specific calculation formula of the binary function obtained by the present invention can be conveniently realized through the DCS configuration, and the precise calculation of the multivariate function of the sliding pressure setting value can be realized through the DCS. Real-time optimization of multivariate functions.

Description

technical field [0001] The invention relates to an automatic control technology of a thermal power generating set, in particular to a method, system and medium for real-time optimization of a multivariate function of a sliding pressure operation curve of a thermal generating set. Background technique [0002] At present, in the engineering application of automatic control of thermal power generating units, the sliding pressure operation curve (ie, the setting value of sliding pressure) of thermal power generating units is usually set as a unitary function of unit load. The sliding pressure setting value determined with the unit load as an independent variable can only achieve unit efficiency when certain operating parameters (such as condenser back pressure, extraction steam volume, main steam temperature, etc.) are maintained at a certain value. Optimum, when the operating parameters of the actual working conditions deviate from the fixed value, the sliding pressure setting...
