面向电厂维护的机组诊断服务器设计与实现

Design and Realization of Maintenance Oriented Diagnosis Server System of Generating Unit for Power Plants

针对电厂状态检修的研究现状以及从维护决策对信息需求出发,提出基于多智能代理的机组诊断服务器系统的体系结构,研究了诊断服务智能代理与监控系统(SCADA)、管理信息系统(MIS)和各个专项监测智能代理单元之间的协作机制,详细介绍了系统的总体框架、功能和软件实现中的关键技术。开发实现了基于多智能代理的机组诊断服务器并实际应用到葛洲坝电厂,使电厂在信息集成、全状态监测和协同交互诊断等方面都有较大的提高,而且具有很好的开放性、适应性和可扩展性。

In view of the necessity tor tiarther improvement ot the condition-based maintenance anti in order to sausly the requirements coming from diagnosis decision,the system structure of diagnosis server based on Multi-Agent System （MAS）is proposed.The cooperation among diagnosis decision agent,real time SCADA,Management Information System （MIS）and the isolate condition monitoring agent has been studies.In addition,the features such as structure,function, principle and key technique about this model are discussed in detail.A MAS-based Diagnosis Server System of generating unit is implemented and put into Gezhouba hydropower plant.This greatly improves the whole condition monitoring,cooperative diagnosis and information integration,etc.Furthermore,this system has many better properties such as opening,flexibility and extension.
