Line Loss Management Based On Synchronous Line Loss System

With the increasing demand of the society,the fine demand for the operation management of the distribution network is increasing.The power supply enterprises pay more attention to the line loss management of the medium voltage distribution network.From the angle of the power supply quality,reducing the line loss of the medium voltage distribution network line can improve the quality of the power supply of the distribution network line,and the users can be used more.From the perspective of enterprise interests,reducing the loss of the medium voltage distribution network line can reduce the loss of the enterprise,improve the electricity supply and improve the efficiency of the enterprise.Therefore,the importance of the distribution network loss management is becoming more and more important in the content of the lean management in the distribution network,whether from the economic point of view or from the angle of the power quality.State Grid Corporation fully promoted the "four-point" line loss management,combined with the 10 kV line differential line loss control requirements,the thesis completed the key distribution of the 10 kV gate optimization configuration and multi-source data fusion of complex distribution network Based on the research of accurate identification technology of loss link,a new type of first-time fusion mobile metering device was designed and developed.According to the grid system and the inherent characteristics of the target network,the meshing of complex cable network and overhead network based on target grid was proposed.The method has formed the demand for gate construction and transformation;proposed a phased gateway optimization configuration method based on maximizing weighted line loss and minimum gate construction cost;formulating the gateway configuration principle and four typical configuration modes,effectively guiding and regulating the State Grid Corporationconstruction and reconstruction of the 10 kV sub-line line loss gate.The thesis constructs a multi-source massive line loss data fusion architecture system,and proposes a multi-source information fusion analysis method.The 10 kV line anomaly line based on standardization loss is proposed.The method of automatic identification of damage accurate identification and abnormal line loss has realized multi-dimensional accurate identification of line loss of medium voltage distribution network.The thesis construction of Yangzhou 10 kV line loss line lean management demonstration area,providing practical basis for 10 kV line loss line control and fine loss reduction of distribution network,promoting 10 kV line management mode is promoted in the promotion and application of the State Grid Corporation and the efficient reduction of the distribution network.
