Description
Technical Field
The invention relates to the field of equipment state monitoring, in particular to an information fusion method of power equipment.
Background
The intelligent substation adopts IEC61850 standard, intelligent electronic equipment and information communication technology, establishes standardized, digital and networked substations, and panoramic monitoring of power equipment (including primary and secondary equipment) is an important target of the intelligent substation. The panoramic monitoring depends on the equipment state monitoring technology, and the equipment state monitoring comprises two methods of off-line detection and on-line monitoring. Offline detection has the characteristic of non-real-time performance, and power failure tests are required, so that the actual condition of equipment cannot be reflected, and online monitoring becomes an important means for improving the reliability of the equipment and the availability of a system.
Compared with the secondary equipment state monitoring, people are more concerned about the online monitoring of the primary equipment. The method aims at early research and application of state monitoring of primary equipment such as transformers, circuit breakers and GIS, and is rich in technical means, wide in monitoring range and high in engineering application degree. In recent years, state monitoring systems of primary equipment such as transformers, circuit breakers, GIS and integrated reactive devices are applied to intelligent substations in succession. Taking the state monitoring of the transformer as an example, by collecting key parameters such as dissolved gas in transformer oil, micro water in the oil, local discharge capacity, bushing dielectric loss, iron core grounding current, winding temperature and the like, the purpose of monitoring the health state of equipment can be achieved, the fault reason of the equipment can be favorably found, the service lives of the equipment and components thereof can be predicted, and a dispatching/regulating center can conveniently and reasonably arrange a maintenance plan.
With the rapid development of embedded equipment, mobile terminals and internet of things technologies, the state monitoring of secondary equipment also has developed technical conditions. The secondary equipment is taken as an information medium and is a focus of attention of operation and maintenance personnel, but the secondary equipment only has a self-checking function at present, cannot meet the requirement of remote monitoring, and an intelligent electronic equipment state monitoring system facing important parameters and links such as an equipment power supply, a memory, a CPU, a communication interface, network flow, a secondary circuit and the like is urgently needed to be established. Under the condition, a set of secondary equipment state monitoring system is independently established, so that resource waste and system dispersion are caused, and information among the systems is isolated and cannot be shared and complemented. On the other hand, information such as substation equipment ledgers, test maintenance records and the like to be referred to for remote monitoring is stored in the production management system. The production management system focuses on management, is mainly applied to departments closely related to production management, cannot directly provide necessary related information such as equipment overhaul test management, fault management, inspection management, defect management, running states, nameplates and the like for the transformer substation, and transformer substation operation maintainers need to access a production management system master station in a Web mode to obtain local information, so that inconvenience is brought to field operation and maintenance.

The method is characterized in that secondary equipment state monitoring information is fused, namely an equipment state monitoring information model is expanded by an ICD (interface control document) file of a secondary equipment monomer (comprising a transformer and a switch state monitoring device), the process layer equipment state monitoring information is firstly transmitted to a primary equipment state monitoring device or a measurement and control device through an SV (space vector) or GOOSE (generic object oriented substation event) message, the primary equipment state monitoring device or the measurement and control device transmits the information to a station control layer through an MMS (multimedia messaging service) message, and a bay layer device and the station control layer device directly transmit the state information of the bay layer device and the station control layer to an equipment state monitoring system through the MMS message. The equipment state monitoring system imports the SCD file of the whole station and establishes a mapping relation with the secondary equipment of each interval layer and the station control layer. The equipment state monitoring system serves as a client, secondary equipment of each interval layer and the station control layer serves as a server, the equipment state monitoring system subscribes state monitoring measurement and state quantity information to the secondary equipment, and the substation equipment state monitoring system can obtain state monitoring data of the primary and secondary equipment of the whole station.
Furthermore, the substation side acquires equipment ledger information, maintenance records, operation records, pre-test data, installation and debugging records, equipment defects, operation and maintenance information of similar equipment and other data which have important guiding significance for field operation and maintenance, and the production management system can automatically update production information such as substation equipment maintenance records, operation records and equipment defect management in real time.
As shown in fig. 3, information fusion is realized on the level of the substation equipment state monitoring system through the primary and secondary equipment state monitoring information, the production management system information and the auxiliary system video image in the substation. The production management system provides information display means for each transformer substation in a Web mode, free interaction cannot be achieved, and the problem is solved by remotely calling Web service. The production management system provides an API (Application Service Interface, abbreviated as API) which can be called through Web, the power transformation state monitoring system serves as a Web Service Application program client, and the production management system serves as a Web Service server to provide equipment information such as equipment ledgers, debugging records, maintenance records and the like for the power transformation state monitoring system. The remote invocation Web service encapsulates data in an XML format (i.e., the remote invocation service object, the delivery parameters, and the service object return results are described in XML). XMLSchema defines a set of standard data types, and provides a language extension data type to realize cross-platform operability. In order to avoid illegal calling, the production management system can set the authority for each system visitor.
After the information is fused, the power transformation equipment state monitoring system can acquire the operation and maintenance state and experience data of the similar equipment to guide field maintenance and operation. For example, the method can realize a primary and secondary equipment linkage function by information fusion with a PMS, track equipment fault sources, action processes and processing conditions according to primary equipment state monitoring data during relay protection action, simultaneously call in-station videos or start in-station patrol robots, observe equipment fault images, comprehensively analyze, diagnose equipment faults and pre-judge processing means of the equipment faults.
