Line loss fault positioning implementation method for power system

Abstract

The invention discloses a line loss fault positioning implementation method for a power system. The line loss fault positioning implementation method is implemented by line loss business data simulation modeling, line loss simulation calculation fault positioning analysis, fault information base construction, and fault information library-based operation. The line loss fault positioning implementation method comprises the steps of: extracting fault features, determining condition attributes and decision attributes of corresponding objects, exploring fault modes through association rules, positioning fault sections, and converting the fault modes into simple text description and output the simple text description. According to the line loss fault positioning implementation method, the faultand line loss linkage of a virtual technology is combined, the fault diagnosis information processing of workers and retrograde line loss calculation is accelerated, the fault positioning speed is increased, the fault processing efficiency is improved, the fault is accurately positioned, and a reliable guarantee is provided for continuous loss reduction.

Description

technical field [0001] The invention belongs to the field of electric power information system construction, relates to line loss business in the actual operation and maintenance process of electric power business, and aims to improve the management level of various professionals in line loss management and solve problems such as line loss faults. Background technique [0002] With the continuous change of the national power policy, the competition in the power market has become increasingly prominent, and the improvement of management level, the exploration of internal potential, and the improvement of economic benefits are the problems faced by power supply enterprises. Line loss rate is a comprehensive core economic and technical index for power grid operating enterprises, and strengthening line loss management is a long-term strategic task and systematic project for power grid operating enterprises. At present, the accuracy of line loss statistics depends entirely on the...

Problems solved by technology

At present, the accuracy of line loss statistics depends entirely on the data quality of multiple systems such as source-end marketing applications, power grid equipment (PMS), power consumption collection, electric energy collection, power grid GIS, and SCADA. Currently, data consistency and synchronous management are relatively difficult; in addition, the calculation of line loss involves multiple links such as distribution, purchase, transmission, distribution, and use, and it is necessary to aggregate tens of millions of metering points through various calculation models. Loss abnormality and line loss calculation fault location is very difficult

At the same time, it is difficult for line loss management personnel at all levels to fully understand the on-site faults, source business systems, and line loss system data that affect line loss statistics.

[0003] At present, when the line loss statistics are abnormal, the efficiency of abnormal troubleshooting is low, and the problem cannot be solved in an efficient and timely manner.
