Method and system for intelligently diagnosing operation problem of rural power distribution network

Abstract

The invention relates to a method and system for intelligently diagnosing the operation problem of a rural power distribution network, and the method comprises: (1) analyzing the representation of the current problem of the rural power distribution network, and forming a rule base for the recognition of the current problem of the rural power distribution network; (2) identifying a rule base according to the current problem, and summarizing a problem reason base by using the operation data of each existing system; (3) by using the rule base, carrying out agricultural distribution network current situation problem automatic identification to form a current situation problem list; (4) according to a problem reason library, intelligently diagnosing problem reasons according to the problem list; (5) according to the master-slave tree structure of the equipment, attributing the current situation problems and reasons to specific equipment; and (6) according to the current problems and reasons of the master-slave tree of the equipment, enabling the current problems and reasons to further form power grid transformation project requirements, and carrying out deduplication and overall planning of the requirements. According to the method and the system, the discovery efficiency of the operation problem of the electric power grid is improved, the demand module arrangement difficulty of the primary agricultural distribution network is reduced, and the demand mastered by a planning department is more complete and effective.

Description

technical field [0001] The invention relates to the technical field of power supply path analysis systems, in particular to a method and system for intelligently diagnosing operational problems in an agricultural distribution network. Background technique [0002] Judging from the actual situation at this stage, the overall technical level of the agricultural distribution network is relatively low, mainly as follows: the structure and layout of the agricultural distribution network are unscientific, such as unreasonable line distribution, excessive operating load, and frequent equipment failures; transformer capacity and demand are not enough Matching, resulting in excessive load and line loss; three-phase load balance problems, causing voltage drop, transformer overheating, and line loss increase; line overload operation increases the reactive power of the agricultural distribution network, resulting in high-order harmonics. Rural distribution network project management lac...

Problems solved by technology

[0003] There are also many deficiencies in the planning, design and management of the agricultural distribution network. The leading role of planning has not been effectively played, and there are phenomena such as incomplete demand collection, untimely demand response, unsystematic analysis of measures, and uncontrollable target network structure.
