Technical field
The invention belongs to technical field of automation, be specifically related to a kind of presence appraisal procedure of intelligent substation electrical secondary system.
Background technology
In tradition transformer station, set up detailed test, monitoring and the operation management standard of secondary device, formed rounded system, effectively guaranteed the normal enforcement of secondary function, ensured the safe and stable operation of electrical network.Compared with traditional transformer station, the secondary function of intelligent substation is realized major transformation has been occurred, the function that originally single device is realized is broken down into multiple devices and realizes, and the coupling that function realizes increases greatly, and therefore the performance index of secondary function and the links of whole system are closely related.Because secondary function realization link increases, system is more complicated, while is along with the application of new technology and new equipment, practical experience is relatively deficient, in service at the scene, repeatedly there is secondary function extremely but cannot analyze in time failsafe link, cause the promptly and accurately problem such as failure judgement equipment and failure cause, timely discovery and the elimination of fault are affected, for system safety stable operation has brought hidden danger.Simultaneously, at present in intelligent substation process of construction, due to a large amount of new technologies and the on-the-spot application of new equipment input, the monitoring standard of intelligent substation electrical secondary system and operation management standard are not yet issued, various places are all according to the fulfillment capability of own strength and existing equipment, work out the operation management standard that is applied to local intelligent transformer station, the monitoring management of electrical secondary system is continued to use to traditional transformer station pattern mostly, Contents for Monitoring is relatively simple, utilize the state estimation of manually realizing electrical secondary system according to monitoring result, level and the degree of depth differ.Popularize the construction period in an all-round way along with intelligent substation enters, the operation management level of intelligent substation electrical secondary system is needed lifting badly, when new technology, new equipment are popularized in an all-round way, must take into account this fundamental requirement of security and stability of system.
In prior art, the local on-line monitoring scheme that the secondary device of indivedual types is carried out, just collection information, need manual analysis, and information integrity and the availability of collecting are not passed through complete demonstration, limited to the help of user's artificial judgment, still need a large amount of manual interventions.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of presence appraisal procedure of intelligent substation electrical secondary system, reduce the risk that different personnel's experience difference causes error in judgement, shorten the time of investigation fault, the non-planned outage and the maintenance that reduce intelligent substation stop the labour time, have saved site examining and repairing workload.
In order to realize foregoing invention object, the present invention takes following technical scheme:
The presence appraisal procedure that a kind of intelligent substation electrical secondary system is provided, described electrical secondary system comprises secondary network and secondary device, said method comprising the steps of:
Step 1: monitoring secondary device presence;
Step 2: gather secondary device presence and secondary network presence to object database;
Step 3: the presence to electrical secondary system is assessed.
In described step 1, secondary device presence comprise environment presence, protection presence, observing and controlling presence, merge cells presence, can only control box presence, server presence, clock presence, record ripple presence and communication apparatus presence.
In described step 2, by stand interior network collection secondary device presence and secondary network presence to object database.
Described station Intranet ruton is crossed IEC61850 and is gathered secondary device presence, and gathers secondary network presence by SNMP.
Described object database is deposited data to be analyzed, intermediate data and the historical data from monitored secondary device; Described object database is real-time data base.
Described expert knowledge library is deposited the accident analysis of electrical secondary system simultaneously.
In described step 3, the inference machine of electrical secondary system online evaluation information substation mates screening by the information in object database with the condition in expert knowledge library, expert knowledge library provides suggestion for operation and assessment result according to coupling, the suggestion for operation that interpreter provides expert knowledge library and assessment result are presented to man-machine interface intuitively, realize the mutual of information and operating personnel.
Presence to electrical secondary system is assessed, the report of reaching a conclusion, and described conclusion report comprises description, fault rank, fault point and maintenance suggestion and early warning, degree of risk and the maintenance suggestion to incipient fault to having broken down.
Compared with prior art, beneficial effect of the present invention is:
1. realize the on-line monitoring of electrical secondary system, for intelligent substation electrical secondary system repair based on condition of component provides effective detection means, shorten the time of investigation fault, reduce the risk that different personnel's experience difference causes error in judgement, shorten the time of investigation fault, the non-planned outage and the maintenance that have reduced intelligent substation stop the labour time, have saved site examining and repairing workload, have promoted overall economic efficiency;
2. the present invention has proposed the electrical secondary system online evaluation information substation based on artificial intelligence technology on framework, and operates in the expert knowledge library on this platform, and data type and reliable criterion through demonstration are provided;
3. comprehensively secondary device and the network state of monitoring intelligent transformer station of this method, and can automatically assess state, draw result intuitively, without the initial data of human interpretation large amount of complex.
Accompanying drawing explanation
Fig. 1 is the presence appraisal procedure flow chart of intelligent substation electrical secondary system.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As Fig. 1, a kind of presence appraisal procedure of intelligent substation electrical secondary system is provided, described electrical secondary system comprises secondary network and secondary device, said method comprising the steps of:
Step 1: monitoring secondary device presence;
Step 2: gather secondary device presence and secondary network presence to object database;
Step 3: the presence to electrical secondary system is assessed.
In described step 1, secondary device presence comprise environment presence, protection presence, observing and controlling presence, merge cells presence, can only control box presence, server presence, clock presence, record ripple presence and communication apparatus presence.
In described step 2, by stand interior network collection secondary device presence and secondary network presence to object database.In standing, network is the mutual bridge of online monitoring system and evaluating system, is also the carrier of intelligent substation business information, and the state of itself is also detected object.
Described station Intranet ruton is crossed IEC61850 and is gathered secondary device presence, and gathers secondary network presence by SNMP.
