Description
Technical field
It is fast more particularly, to a kind of event of failure based on multi-source data the present invention relates to electric network fault analysis field
Quick-recovery householder method.
Background technology
For now, when electric network fault event is handled, various fault message Statistical Criterias are more messy in China,
Standardization and standard system are not formed, and multi-source data information format and information protection system are relatively simple.The risk of power grid still according to
Shown by classical pathway, be unfavorable for the weak link that operation maintenance personnel intuitively understands power grid.Therefore, in order to tackle and handle in time
Electric network fault event is, it is necessary to establish automatic fault recognition system, the countermeasure that trouble-shooting recovers rapidly, to ensure operation of power networks
Security.
After accident generation, disposal process relies on dispatcher's experience, it is impossible to effectively and rapidly formulates recovery policy.Accident
Recovery policy afterwards relies the experience of dispatcher entirely, it is difficult to make judgement promptly and accurately, speed is slow and there are certain risk.
The content of the invention
The present invention is at least one defect overcome described in the above-mentioned prior art, there is provided a kind of failure based on multi-source data
The fast quick-recovery householder method of event, makes dispatcher very clear to the effect of the recovery policy, while can also set a variety of extensive
Multiple strategy, carries out comparing calculation to each tactful result, allows dispatcher can be with better choice optimal policy.

S212:Call trend software;
S213:Obtain trend software calculated value;
S214:Update 10kv bus load values;
S215:Return to step S221;
Wherein, the trend software provides the electric network swim value service that calculates, this software is called by remote service and interacted,
Invoked procedure is to be passed to user's pseudo operation parameter device mark and equipment state, trend software root to trend software by interface
Backward the system, which is calculated, according to parameter returns to the electric network swim value after calculating.
Further, in step s 2, determine whether not travel through section, if so, then return to step S1, if nothing, into
Enter step S3.
Further, in step S1, S2, the common information model data timing of data acquisition and supervisor control pushes away
Generation power grid topology model is sent, topological analysis is carried out by power grid topology model.
Further, in step s3, next recovery policy is determined whether, if so, then return to step S1, if nothing,
Then enter step S4.
Wherein, data acquisition is that computer-based dcs and electric power are automatic with supervisor control
Change monitoring system;In electric system, data acquisition and supervisor control the operational outfit at scene can be carried out monitoring and
Control, to realize data acquisition, equipment control, measurement, parameter regulation and various types of signal alarm various functions.Data acquisition with
Supervisor control provides data below and supports, common information model model, measurement information, user data, failure source information.
Wherein, common information model is an abstract model, describes all main objects of electric power enterprise, particularly with electricity
Power runs related object.Power system resource is represented by providing a kind of relation with object class and attribute and between them
Standard method.By defining a kind of common language based on common information model(That is syntax and semantics)So that these application or
System can access common data and exchange information to realize independent of the internal representation of information.This method is adopted from data
Collection obtains common information model model data with supervisor control, and electric network data is obtained by parsing common information model model
And topological structure of electric.
Compared with prior art, beneficial effect is:After electric network fault, dispatcher by rule of thumb can only recover power grid,
And can not know the precise effects of operation of power networks under the reset mode, and in this way, dispatcher can simulate setting power grid
The method of operation, calculates the N-1 risk informations of the section under the method for operation, allows effect one mesh of the dispatcher to the recovery policy
It is clear, while a variety of recovery policies can also be set, comparing calculation is carried out to each tactful result, makes dispatcher more preferable
Select optimal policy.
