Grid fault locating system and method based on multisystem information integration

Abstract

The invention relates to a grid fault locating system based on multisystem information integration. The grid fault locating system comprises a main station, a concentrator and fault indicators, wherein the fault indicators are installed on a line. The fault locating system is installed on the main station and the main station communicates with the concentrator in a GPRS communication mode. The concentrator is connected with the multiple sets of fault indicators in a radio frequency communication mode. The grid fault locating system further comprises a distribution network geographic information system, a distribution network automatic system, a fault intelligent diagnosis system and a distribution production management information system, wherein the distribution network geographic information system, the distribution network automatic system, the fault intelligent diagnosis system and the distribution production management information system are connected with the main station respectively. The main station is further connected with cellphones of emergency maintenance operators in a text message mode. The invention further relates to a grid fault locating method based on multisystem information integration adopting the system. An information integrated technology provided by multiple systems is utilized to replace single fault indicator movement information to conduct comprehensive locating on the positions where faults occur, the faults are accurately located, and reliability is high.

Description

Technical field [0001] The invention relates to a grid fault location system based on multi-system information integration. The invention also relates to a grid fault location method based on multi-system information integration using the system. Background technique [0002] With the rapid economic development and the improvement of people’s living standards, people’s requirements for reliable power supply and high-quality services will become higher and higher. The distribution network system is at the end of the power system and is directly responsible for the power supply and distribution of customers. The operating level of the network system directly affects the quality of power supply for customers. [0003] The distribution network system has many branch lines and complicated wiring. When a line fails, the point of line failure is generally difficult to find. It usually takes a lot of manpower, material resources and time, which seriously affects the reliable power supply ...

Problems solved by technology

[0005] At present, only the action information of a single fault indicator is used to locate the fault. Since the fault indicator is installed on the site, the environment is harsh, and the fault indicator is sometimes in the debugging state, and there are often phenomena such as wrong action information. The fault indicator displays information Not completely reliable, resulting in inaccurate fault location technology and low reliability
