Background technology
In the 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.Compare with traditional transformer station, the secondary function of intelligent substation realizes having occured major transformation, originally the function of single device realization is broken down into a plurality of devices and realizes that the coupling that function realizes increases greatly, so the links of the performance index of secondary function and whole system is closely related.Because the 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, it is unusual but can't in time analyze failsafe link secondary function repeatedly to occur, causes the promptly and accurately problem such as failure judgement equipment and failure cause, timely discovery and the elimination of fault have been affected, for system safety stable operation has brought hidden danger.Simultaneously, at present in the intelligent substation process of construction, because a large amount of new technologies and new equipment drop into the field, 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, worked out the operation management standard that is applied to local intelligent transformer station, the monitoring management of electrical secondary system is continued to use 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 of system stability.
In the prior art, the local on-line monitoring scheme that the secondary device of individual types is carried out, just collection information, need manual analysis, and information integrity and the availability of collecting are not passed through complete demonstration, and be limited to the help of user's artificial judgment, still needs 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 differences cause 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 the site examining and repairing workload.
In order to realize the foregoing invention purpose, the present invention takes following technical scheme:
A kind of presence appraisal procedure of intelligent substation electrical secondary system is provided, and 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 the described step 1, the secondary device presence comprise environment presence, protection presence, observing and controlling presence, merge cells presence, can only the control box presence, server presence, clock presence, record ripple presence and communication apparatus presence.
In the 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 the secondary device presence, and gathers the 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 the described step 3, the inference machine of electrical secondary system online evaluation information substation mates screening with the information in the object database and the condition in the expert knowledge library, expert knowledge library provides suggestion for operation and assessment result according to coupling, interpreter is presented to man-machine interface intuitively with suggestion for operation and assessment result that expert knowledge library provides, and realization information and operating personnel's is mutual.
Presence to electrical secondary system is assessed, and the report of reaching a conclusion, the report of described conclusion comprise to the description of having broken down, fault rank, fault point and maintenance suggestion and to early warning, degree of risk and the maintenance suggestion of incipient fault.
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, shortened the time of investigation fault, reduced the risk that different personnel's experience differences cause 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 the site examining and repairing workload, have promoted overall economic efficiency;
2. the present invention has proposed electrical secondary system online evaluation information substation based on artificial intelligence technology at framework, and operates in the expert knowledge library on this platform, provides through the data type of demonstration and reliable criterion;
3. comprehensively secondary device and the network state of monitoring intelligent transformer station of this method, and can automatically assess state, draw intuitively result, need not the initial data of human interpretation large amount of complex.
Description of drawings
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.
Such 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 the described step 1, the secondary device presence comprise environment presence, protection presence, observing and controlling presence, merge cells presence, can only the control box presence, server presence, clock presence, record ripple presence and communication apparatus presence.
In the described step 2, by stand interior network collection secondary device presence and secondary network presence to object database.Network is the mutual bridge of online monitoring system and evaluating system in standing, and also is the carrier of intelligent substation business information, and the state of itself also is the object that is detected.
