Intelligent hydropower station whole-process construction system based on IEC 61850

Abstract

The invention discloses an intelligent hydropower station whole process construction system based on IEC 61850. The method comprises the steps of a technology accumulation process, demand analysis, formulation of an overall scheme, and scheme auditing and modification. The technology accumulation process comprises data collection, field research and technology exchange; the formulation of the overall scheme comprises the steps of hydropower station physical object hierarchical division, information object modeling, communication system construction, integrated management and control platform construction and intelligent business application. Wherein the physical object hierarchical division stage expresses a hierarchical relationship of actual physical device objects; in the information object modeling stage, an information object model is divided into a server, a logic device, a logic node, a data object and a data attribute; the communication system construction comprises a communication interface, a communication protocol, communication protocol conversion and a communication network; the integrated management and control platform comprises a data center, a basic service platform and an intelligent application platform. The system has the advantages of realizing hydropower station data sharing and fusion and system interconnection and intercommunication.

Description

technical field [0001] The invention relates to the technical field of intelligent hydropower stations, and more specifically, relates to an IEC 61850-based whole-process construction system for intelligent hydropower stations. Background technique [0002] With the continuous development of intelligent hydropower stations, hydropower stations will be faced with an ever-increasing amount of engineering data, and the communication standards adopted by various industries involved in hydropower stations are different, which will directly lead to the exacerbation of the problem of data islands and the inability to implement data structures. The sharing and integration of hydropower stations have seriously hindered the development of intelligent hydropower stations. [0003] Compared with hydropower stations, smart substations based on the IEC 61850 communication standard have been successfully applied in a large number. Compared with the conventional computer control and protec...

Problems solved by technology

However, in the field of hydropower station automation, due to the fact that the current technical standards and specifications for the intelligent construction of hydropower stations are not perfect enough, there is still a lack of consensus on the direction of technological development. Insufficient evaluation system and other deficiencies, the smart hydropower station based on IEC 61850 has always been difficult to achieve significant progress and good results
