Abstract

The invention belongs to a synchronous line loss anomaly analysis method, and particularly relates to a synchronous line loss comparative analysis method based on theoretical line loss calculation. Apower transmission network is analyzed through an ETL assembly, a power distribution network model is automatically updated and automatically matched with a same-period system, and theoretical partialpressure, power transmission line loss, wiring loss and transformer area loss are generated through combination of a partial pressure calculation relation automatic generation technology based on electric quantity classification expansion and theoretical calculation. On the basis of combination of gateway automatic matching and manual matching, comparative analysis with the line loss in the sameperiod is realized. By means of the technology, the conditions that the number of abnormal reasons of the synchronous line loss system is large, and the troubleshooting process is complex are improved. The multi-dimensional difference analysis method for comparing the same-period line loss result with the theoretical line loss result assists the same-period line loss system in quickly positioningthe cause of the abnormal line loss, and lays a foundation for loss reduction potential analysis.

Description

technical field [0001] The invention belongs to a method for abnormal analysis of synchronous line loss, in particular to a method for comparative analysis of synchronous line loss based on theoretical line loss calculation. Background technique [0002] The current line loss calculation items for the same period include partition, voltage division, bus level, transmission line, wiring and station area. The calculation process is to first extract the grid structure and equipment model, and then manually set the gateway model configuration relationship of the line loss calculation item for the same period , and then obtain the operating data, and finally calculate the line loss for the same period according to the pass model. There are many abnormal factors of line loss in the same period, mainly as follows: 1) Incomplete model account: the basic account of the line loss model in the same period is missing, resulting in incomplete equipment; 2) Gateway model configuration err...
