Fault classifier for transient detection of power distribution system

Abstract

The invention discloses a fault classifier for transient detection of a power distribution system. The fault classifier comprises a detection system processor, a display control module, a fault classification module, a signal preprocessing module, a sensor detection module, a system detection module, a signal acquisition module, a sensor module and a power distribution system module. The inventionrelates to the technical field of power distribution system fault detection. Based on the fault classifier for transient detection of the power distribution system, the input end of the signal preprocessing module is respectively connected with the output ends of the sensor detection module and the system detection module; the first detection module, the first judgment module, the second detection module and the second judgment module respectively detect transient currents in the sensor and the power distribution system. Fault judgment is carried out while detection is carried out, faults ofthe power distribution system can be detected, judged and classified in time, the influence of the faults of the power distribution system on resident power is reduced, and different fault informationis classified and processed through the fault classification module.

Description

technical field [0001] The invention relates to the technical field of fault detection of power distribution systems, in particular to a fault classifier for transient detection of power distribution systems. Background technique [0002] Traditionally, the power system is divided into three major systems: power generation, power transmission and power distribution. The power generated by the power generation system is transported through the power transmission system, and finally distributed to each user by the power distribution system. Generally, the power system is divided from step-down distribution The system from the outlet of the electric substation (high-voltage distribution substation) to the user end is called the power distribution system. The power distribution system is composed of a variety of power distribution equipment (or components) and power distribution facilities to transform voltage and directly distribute to end users. An electrical network system of...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a fault classifier for transient detection of power distribution system, which solves the problem that the fault classifier for transient detection of power distribution system is difficult to judge the specific location of transient , it is impossible to detect whether it is a sensor failure or an internal failure of the distribution system, which causes the distribution system to be paralyzed, affects the normal use of residents' electricity, and has no obvious effect on the transient detection and fault location classification of the actual distribution system.
