水电厂维护分布式协同决策支持系统研究

状态检修是一个系统工程，受制于设备的健康状态、水情、电力市场需求等多方面的条件，为了减少停机时间和维修费用，电厂正在逐步从计划检修向状态检修过渡，如何实现维修人员、专家和计算机之间的协调是非常重要的。因此该文设计了面向水电厂维护的分布式协同决策支持系统（MoDCDSS），探讨了采用计算机支持的协同工作（CSCW）、智能代理与虚拟现实技术实现分布式协同诊断决策的原理和方法，详细介绍了系统的目标、框架和系统功能，以及软硬件实现方法。系统已经在葛洲坝电厂投入运行，结果良好。

MAINTENANCE ORIENTED DISTRIBUTED COOPERATIVE DECISION SUPPORTED SYSTEM FOR HYDROPOWER PLANT

Condition-based maintenance (CBM) is a systematic project, and the information coming from equipments condition, water and market must be all taken into account. In order to reduce the equipment downtime and the maintenance cost, the maintenance strategy in hydropower plants has to be progressively changed from time-based maintenance (TBM) to CBM. It is very important issues that how to achieve the harmony among the operator, expert and the computer, maintenance oriented distributed cooperative decision supported system (MoDCDSS) for hydropower plants is presented in this paper. The principle and the method of distributed cooperative diagnosis decision making are discussed, which adopt three technologies, such as computer supported cooperative work (CSCW), agent and virtual reality (VR). The systematic goal, framework and function are particularly introduced, and the implementation method of hardware and software is proposed. The MoDCDSS has been already put into operation in Gezhouba hydropower plants, the result shows good.
