Abstract:In order to evaluate the equivalence of power outage test and power outage detection technology, a model of power off-line test and on-line detection technology equivalence analysis based on AHP(analytic hierarchy process) is proposed. Firstly, the standard layer composed of accuracy, validity and fault detection ability and the index layer composed of seven indexes such as data numerical accuracy are determined according to the state quantity acquisition process of the two technologies. The weight coefficient of each index is calculated by AHP, and a two-level equivalence evaluation index system is established. According to the properties of each indicator in each indicator layer, the quantitative method and the normalized calculation method of each indicator layer are determined. Aiming at the characteristics of unequal number of data and mismatch of time series of power outage test and power outage test, a data preprocessing method with three spline interpolation fitting is proposed, and an equivalence analysis model is finally established. The example shows that this model can reduce the human intervention, and the equivalence of on-line detection to power failure test can be evaluated by synthesizing the main stage of state variable data acquisition.
