Method for computing new index for evaluating unit AGC regulation performance

The invention discloses a method for computing a new index for evaluating unit AGC regulation performance, comprising the following steps that actual outputs and target outputs of all units participating into AGC regulation are recorded per 5 seconds; and a computing unit tracks the correlation index C, delay index D, mileage index M, precision index P and overall regulation performance index K of an AGC control command. The method provided by the invention completely adopts the unit to track the historical data of the actual output and target output of the AGC control command without being influenced by set unit evaluation parameters, so that the time frame of the unit with poor tracking effect can be effectively recognized, the regulation performance of the AGC unit for tracking the AGC control command can be comprehensively and accurately evaluated, and the regulation performance of the unit under different running states can be highlighted through modifying different performance index weights.
