Problems solved by technology
[0002] At present, the degree of automation of distribution network in counties in my country is generally not high. Generally, all kinds of equipment in substations are monitored through the SCADA system, and there is still a lack of effective tools for real-time monitoring of the operation of the distribution network. This makes the distribution network Operators cannot accurately grasp the operating parameters and operating status of distribution network lines in real time
In the actual operation and management, after the distribution line fails, the operator often adopts the most "primitive" method of receiving the alarm and patrolling the line to troubleshoot the distribution line, which greatly affects the work efficiency and is not conducive to the user's power supply. Improvement of reliability index

The invention discloses a county region distribution network operation fault analysis and diagnosis platform. The platform comprises an operation monitoring and warming module, a fault diagnosis auxiliary module, an EMS model splicing and mapping module and an electrical island map extracted GPMS full net diagram module. The county region distribution network operation fault analysis and diagnosis platform provides timely fault warming and fault judgment auxiliary means, can basically judge a fault position, meanwhile can preliminarily the failure property, provides timely information for distribution network dispatching and rush-repairing commanding staff, accomplishes fault diagnosis and positioning within the shortest time, reduces the distribution network fault power service interruption time, and enhances the service level of electric power companies.
Description
technical field [0001] The invention relates to a fault analysis and diagnosis platform, in particular to a fault analysis and diagnosis platform for county distribution network operation. Background technique [0002] At present, the degree of automation of distribution network in counties in my country is generally not high. Generally, all kinds of equipment in substations are monitored through the SCADA system, and there is still a lack of effective tools for real-time monitoring of the operation of the distribution network. This makes the distribution network Operators cannot accurately grasp the operating parameters and operating status of distribution network lines in real time. In the actual operation and management, after the distribution line fails, the operator often adopts the most "primitive" method of receiving the alarm and patrolling the line to troubleshoot the distribution line, which greatly affects the work efficiency and is not conducive to the user's powe...
