琅琊山抽水蓄能电站位于滁州市西南郊的琅琊山麓，是由奥地利政府出口信贷支持的重大项目和安徽省“861"重点建设项目。电站总装机容量60万千瓦，装设4台单机容量为15万千瓦的单级可逆式抽水蓄能机组。整个电站枢纽部分由上水库、输水系统、地下厂房、下水库和地面开关站5部分。电站建成后，将在电网中发挥调峰填谷、调频调相和紧急事故备用等重要作用，将改善安徽省及华东电网的火电机组运行条件，提高电网运行的安全可靠性和经济性，经济效益和社会效益都十分显著。 
　　　　琅琊山水电站公用及通风空调设备采用多层式控制，主控工作站设1台公用设备上位机，各个子系统设就地控制单元，在主控及网络失效的情况下，就地控制单元仍能独立完成其系统内设备的监测和控制功能。 
　　　　各就地控制子系统采用PLC为控制系统，对于PLC要求有较高的性价比。该蓄能电站选用ABB AC31系列可编程控制器。ABB AC31系列可编程控制器可以完成辐射几百米甚至几公里的分布式应用，并且具有经济可靠、配置灵活、通讯功能强大等特点，*该蓄能电站的控制要求。 
　　　　系统网络结构见下图：
　　

　　公用设备主控工作站负责协调合管理公用设备就地各子系统的工作，记录和计算运行信息，并把经过处理的数据存入数据库中，同时完成公用及通风空调设备的远方监测和远方控制功能。各子系统站分别为：厂内渗漏排水泵系统、低压空压机系统、消防泵和雨淋阀控制系统、通风空调系统，ABB AC31 50系列可编程控制器系统负责对各子站进行控制。其中，通风空调系统分为主厂房、副厂房、安装场副厂房以及出线竖井几个远程控制站，每个远程控制站又分别由几套远程I/O进行分散控制，远程I/O选用50系列Modbus远程扩展模块，不仅提高了系统的性价比，而且能够保证系统的稳定运行。每套PLC子站都采用MODBUS协议与公用设备上位机进行通信，子站与主控工作站的距离长为1380米。整套系统利用了ABB AC31系列可编程控制器的优势，实现了优化的控制。 该套系统计算机监控软件采用杰控Fameview软件，FameView是一套实现工业数据采集、过程监控、数据管理的高性能工业自动化软件，它具有强大的图形功能、变量、图形替换的模块化功能，通讯速度以及画面刷新的速度很快，同时还集成手机短信、数据处理和报警等服务。 
　　　　整个系统设计合理、操作简单、安全可靠，系统投入运行后*达到用户要求，并且一直运转良好，得到了用户的好评。
