The design idea adopts<br/>delamination distributing module. It was divided into stage control layer and spacing layer and was joined via<br/>communications network between the two layers. Functions of the SCADA system include data collection and disposal、<br/>surveillance and alarm, control operation, statistics account, synchro time adjusting, tele-control, electric energy measure<br/>and self-diagnosis.<br/>Keywords: Power plant; Monitoring and controlling system; LNG (liquefied natural gas)<br/></font></p>
