Problems solved by technology

At present, power enterprises at all levels have established a relatively complete power secondary system, but in the power production and operation, factors such as equipment quality, human misoperation, natural disasters, etc., have inevitably caused the equipment operation reliability of the intelligent substation automation system decline, which directly threatens the safe and stable operation of primary power equipment
At present, the problems faced by the operation and maintenance supervision of the smart substation automation system are more complicated and diverse. One is that the collection of information is too simple. The information is difficult to reflect the operating status of the system and equipment in detail, which brings difficulties to the abnormal location and cause analysis of the system
The second is the lack of correlation between events, and the lack of correlation analysis between smart substations and business automation system event information, making it difficult to achieve overall risk management
The third is that the fault site cannot be accurately analyzed. Once the intelligent substation automation system fails, due to the many links involved in data collection and the lack of a logical model for data services, it is difficult to analyze and locate the cause of the fault

Abstract

The invention discloses an abstraction method specific to an operation and maintenance information model of an intelligent substation automation system. The method comprises the following steps of: generating physical network topology of the intelligent substation automation system and basic parameters of the physical network topology; decoupling an operation and maintenance supervision target and establishing an operation and maintenance information model; abstracting security feature constraint data streams, system functional service data streams and system performance data streams in sequence, and adding the data streams into the operation and maintenance information model; and establishing a multi-state set comprehensive index for reflecting an overall running condition of the intelligent substation automation system, and displaying and outputting the established multi-state set comprehensive index through a substation operation and maintenance supervision human-machine interface. Based on multi-thread path searching, system faults or anomalies can be found more rapidly; the current situations of a substation secondary system in the aspects of security, reliability, availability and the like are assessed accurately; potential running troubles are found; the origins of the faults are traced; the influence ranges of the faults are located; and the fault spreading trend is predicted.

Description

technical field [0001] The invention relates to the operation and maintenance supervision technology of the substation secondary system, in particular to an abstract method for the operation and maintenance information model of the intelligent substation automation system. Background technique [0002] The operation and maintenance supervision of the smart substation automation system is quite different from the general IT system network management. The main reason is that the monitoring objects are obviously different and the data collection methods are similar. Difficult to apply. Therefore, in view of the special protocol adopted by the intelligent substation automation system and the particularity of the information environment, it is necessary to break through the limitations of the general IT system network management method to meet the needs of the site. [0003] In recent years, with the rapid development of power communication network and computer information techn...
