Full research and judgment method for fault handling of power distribution network

Abstract

The invention relates to a full research and judgment method for fault handling of a power distribution network. The method comprises the steps of establishing a full research and judgment fault handling closed-loop management process which transversely covers all fault types of the power distribution network, covers common faults such as short-circuit faults, phase failure faults, bus voltage loss, ground loss faults and line heavy overload of the power distribution network, is close to a fault handling service of the power distribution network and longitudinally penetrates through the processes of fault sensing, fault analysis, isolation and power conversion, fault emergency repair, power transmission operation, ending and the like in a DMS system; and after the DMS system receives alarminformation of various faults, performing active fault research and judgment sensing after effectively analyzing and identifying fault signals, and comprehensively analyzing out a research and judgment result, thereby facilitating operations such as field search isolation, power transfer and the like. According to the method, full-type decision making, full-information monitoring, full-online management and control and full-process control of the faults of the power distribution network can be realized, the handling efficiency and management and control strength of the faults of the power distribution network are further improved, and the safety, high efficiency and standard management level of operation and fault handling of the power distribution network is comprehensively improved.

Description

technical field [0001] The invention belongs to the field of power system distribution automation, and in particular relates to a comprehensive research and judgment method for distribution network fault disposal. Background technique [0002] In recent years, Fujian distribution automation master station system has preliminarily realized the integration of operation, distribution and dispatching data, considerable and controllable distribution network operation status, and the application of short-circuit fault research and judgment of multi-source information, which has effectively improved the automation level of distribution network. However, there are still failure procedures that are not standardized enough, failure research and judgment coverage is insufficient, failure handling efficiency is not high, process safety control is weak, and post-event analysis and evaluation are difficult. In order to achieve the construction goal of "full research and judgment, full rem...
