智能水电厂防汛决策支持系统是智能水电厂专家决策支持系统的重要组成部分。本文通过对水利和电力行业相关标准的深入分析,以及对基于SOA的系统框架、基于Ajax的WebGIS设计和基于工作流的应急预警技术等诸多关键技术的研究,设计并开发了满足智能水电厂相应业务需求的防汛决策支持系统。目前已成功应用于吉林省松江河智能水电厂,可以为国内相关智能水电厂防汛决策支持系统的设计和建设提供参考。 Flood control decision support system for smart hydropower plant is an important part of intelligent hydropower plant expert decision support system. In this paper, through in-depth analysis of relevant standards in water conservancy and power industry, as well as many key technologies such as SOA-based system framework, Ajax-based WebGIS design and workflow-based emergency warning technology, Flood control decision support system for business needs. At present, it has been successfully applied to Songjianghe Smart Hydropower Plant in Jilin Province, which can provide reference for the design and construction of flood control decision support system for related domestic smart hydropower plants.
