The standardized degree of electric protection system is higher, has covered relay protection system O＆M information needed substantially, these information belong to
Logical node under Different Logic equipment is closed by the form group of data set and send to main website or support to be viewed locally, is relay
The intelligent O＆M of protection provides data supporting.The multi-source data of intelligent warning system can be built based on the structure of data set, respectively
The content of data set is as shown in Fig. 2.
(2) data are sorted out
From the function realization of intelligent alarm, the data from different data sources carrier can be divided into three classes：Run shape
State data, device status data and relaying configuration data.
Running state data is usually generated by the excitation relay protection response of primary side failure, and main includes protective device
Action situation；And device status data mainly reflects the operating mode of relay protection system each device and secondary circuit；If analyzed
Relay protection system whether there is abnormality, other than needing above-mentioned two parts data, it is also necessary to relaying configuration data, protection
Configuration data predominantly determines the information such as the required definite value of current relay protected operation mode, pressing plate.
Each data set of intelligent warning system Various database can be integrally subdivided into evaluation of running status database,
Equipment state rating database and relaying configuration database；As shown in Figure 3.
(3) intelligent alarm method is adapted to
In order to make full use of relay protection Various database, need to check and divide according to disparate databases, including consistency
Analysis, four class of tendency check analysis, logic analysis and abnormality alarming.

Tendency state check analysis be based on device it is hard/characteristic that is gradually deteriorated with run time of software health status,
By continuously monitoring simultaneously analytical equipment status data, its trend changed over time is obtained, by the way that threshold value is arranged, and calculates state
Data between threshold value at a distance from be used as state evaluation index.It is suitable for utilizing the equipment shape with slowly varying trend at any time
State data are compared by and with threshold value (rated value), can obtain check analysis result.Its basic principle is as shown in Equation 1：
2) consistency check analysis
Coherency state check analysis is whether unanimously to judge state by comparing canned data and real data, is applicable in
In using with constant characteristic relay protection scheme data extract relay protection crucial state, only need to utilize monospace information into
Row status monitoring.It realizes that basic principle is：First device definite value, configuration file check code and journey are always called together when relay protection puts into operation
The information such as sequence version, and preserved in monitoring backstage.When operation, consistency intelligent alarm is carried out by 1 time/month frequency：Read definite value
Etc. information, and with O＆M backstage confirm fixed value list compared, it is continuously inconsistent three times, alarm.Or works as and detect device
After restarting, consistency intelligent alarm is triggered immediately.Define a kind of XOR operationSo that when a with b differences,
Then consistency check analysis basic principle can be summarized as shown in Equation 2：
3) logic analysis
It is as follows based on the logic analysis thinking for measuring value information：
4) abnormality alarming
According to the various intelligent alarm methods of adaptation can obtain relay protection state it is whether abnormal as a result, if it find that
It is abnormal, then the exception in the form of warning information is notified into operation maintenance personnel, facilitates the development of maintenance work.
It summarizes
The present invention combs the data needed for assessment relay protection state from the angle of multi-source data comprehensively, and proposes intelligence
The framework of substation relay protection intelligent warning system.The present invention has inquired into information source and the acquisition side of intelligent warning system
Formula classifies to these status informations, and corresponding intelligent alarm method is adapted to according to classification.The intelligent alarm that the present invention is built
System can monitor all kinds of status informations of relay protection in real time, provide the various check analysis methods of adaptation and find state in time
