Feeder OP Data Interconnection and Matching Based on α-DDTW Algorithm and Power Waveform Similarity
OP interconnection refers to the effective correlation of ledger data maintained in the Operation Management System(OMS)and the Power Production Management System(PMS)within the power supply enterprise.It serves as the foundation for enhancing the level of grid management and production efficiency.Addressing the complexities and inefficiencies in the OP interconnection process for 10 kV feeder lines in the medium-voltage distribution network,as well as the lack of effective verification mechanisms,a method for verifying and matching OP data for feeder lines based on multi-source measurement data and system ledger information of the distribution network is proposed.Firstly,power information and equipment parameters are extracted from the OMS and PMS systems,and ledger and power are preprocessed to form a successful time-series matrix.Then,based on α-DDTW distance,the similarity of power waveforms on both sides of the feeder line is evaluated,automatically achieving verification and correlation matching of feeder line OP data.Finally,through case analysis using actual system data from a power company in East China,the effectiveness and practical engineering application value of the proposed method are validated.
