System and method for acquiring relation curve of power and power supply coal consumption of coal-fired power generating unit

Abstract

The invention provides a system and a method for acquiring a relation curve between power and power supply coal consumption of a coal-fired power generating unit. The method comprises the following steps: step 1, selecting an original data frame from historical data of the coal-fired power generating unit; step 2, obtaining an effective data frame from the original data frame; step 3, obtaining a power characteristic matrix; obtaining a daily power supply coal consumption correction value column vector corresponding to each effective data frame; step 4, drawing a relation curve between the power of the coal-fired power generating unit and the power supply coal consumption by using the power characteristic matrix obtained in the step 3 and the daily power supply coal consumption correction value column vector; according to the method, the relation curve of the power and the power supply coal consumption of the coal-fired power generating unit is obtained by using the actual operation parameters of the coal-fired power generating unit, so that the defect of high cost of the existing performance test method can be effectively solved, and the curve can be used for further diagnosing and analyzing the performance status and trend of the power station by energy-saving workers; and the power station performance is mastered in real time and energy-saving and consumption-reducing.

Description

technical field [0001] The invention relates to the field of coal-fired power generation, in particular to a system and method for obtaining a relationship curve between power of a coal-fired generator set and power supply coal consumption. Background technique [0002] Coal-fired generator sets use the relationship curve between power and power supply coal consumption to describe the economic characteristics under variable load conditions, which is one of the basic tasks for energy-saving analysis and energy consumption diagnosis of units. For coal-fired generator sets, the American Society of Mechanical Engineers (ASME) has issued PTC4, 6 performance test procedures for steam turbines and boilers. The power and coal consumption of the generator set can be obtained through the performance test method. The coal consumption test of the power supply of the unit requires detailed and careful instruments. , load, operation parameter adjustment and other organizational arrangemen...
