【摘要】 将应用于分布式系统控制的SCADA系统引入电厂水源地供水自动化系统,实现了供水系统的"三遥"(即遥控、遥测、遥信)功能,并根据"三遥"量之间的数据约束关系,提出了基于该约束关系的系统自诊断方法,进一步提高供水自动化系统的可靠性。该系统的成功工程应用说明了该系统具有良好的工程应用价值。更多还原

【Abstract】 The supervisory control and data acquisition(SCADA) system is applied to automatic water supply system for power plant,by which the remote control,remote measurement and remote information of the water supply system are realized.The restrictive relation between data from remote devices and the initial values is used to achieve self-diagnosis.Reliability of water supply system is improved farther.The system has been successfully used in a power plant,which means the system has well applicable value.更多还原
