Description
Technical field
The present invention relates to Electric Power Network Planning technical field, and in particular to one kind visualization power network diagnosis of the status quo analysis system.
Background technology
Current power network diagnostic analysis index multi-source is in other systems, and analysis personnel take to be needed to be advised according to power network after data
Draw business characteristic and carry out calculating analysis, overall merit electric network state can be just obtained, so as to diagnose electrical network weak link in time.Power network
Diagnostic analysis index includes including some indexs in comprehensive diagnos, power transmission network diagnosis, power distribution network three classes of diagnosis, each class content,
Each index divides different types to show again, so the index classification to be shown is more, substantial amounts.
Due to without ripe analysis calculating instrument, generally requiring manual calculations key index, and calculation formula compares
Complexity, each index can correspond to different weights, cause calculating cycle longer and the probability of result of calculation error is larger.
The content of the invention
In order to solve the above technical problems, it is an object of the invention to：A kind of visualization power network diagnosis of the status quo analysis system is provided
