[0066] A method for identifying bad data in a distribution network based on quality labels includes the following steps:
[0067] Step 1: Multi-data source acquisition: Under the condition of knowing the whole grid network structure CIM, combine the real-time power P and voltage U obtained from the feeder FTU and bus RTU to derive the load of different types of users from the marketing system (CIS) and the centralized reading system Data, including voltage U, current I, instantaneous active power P, instantaneous reactive power Q, active power measurement and reactive power measurement, forming a data source formulated by the subsequent quality label;
[0068] Step 2: Evaluation of the quality score of each quantity measurement: Under the condition of obtaining multi-source data, use the constraint rules of 6 influence factors of voltage measurement U, current measurement I, active measurement P, active power measurement and reactive power measurement Evaluate the corresponding dat...
