Software Exploitation Of The Power Station Simulator's Logic Protect And Control System

With the devlopment of Control System and Computer Technology,domestic automatization level of electric power industry improve notably. Distributed Control System for short DCS is adopted widely in runing and controlling of power station,so Completeness CRT Simulator basely on DCS System emerge consequentially.With the change of Simulator's style, exploitable tool of Simulator must to be empoldered and improved.The GuiZhou XiShui Power Station's 135MW Set are regareded as a example,the paper sets up a electric system's dynamic maths model,exploits a control configuration software basely on DCS power station simulator,and designs a software of simulator's logic protect(include Electric logic) and control.The FOXBORO DCS is regarded as main reference object,it doesn't same as the traditional simulator.The logic protect and control are separated from model and the configuration control system be exploited in the paper.And the configuration of logic protect and control is operatised at Operation Station Administration System,not to be added into Model,not to build control sound code also. Therefore it comes true the on-line adjusting, real-time control and so on.It sames as real locale.The software of logic protect(include Electric logic) and control includes some usual algebraic and operation model of thermal control and logic operation of logic protect.It adopts FOXBORO's DCS as a example,so we configuration via filling table,user only define I/O condition,fill certain operation variable,and name logic variable.The software offers a friendly user's interface, personnel can compile and modify the control and logic program, change the value of logic and control variable conveniently, attach themselves to run,debug and control the set,not need to know about the inside of the old programs deeply.So the configuration software offer a flat that control engineer can attend to the structure of control loop and logic protect(include Electric logic),not but to handle complicated program.The software improves on the traditional simulator,it is offered not only to operator for simulation training,but also to engineer for designing control configuration and training the control manager The pattern of control configuration accord with the reality ,not need to test in the actual DCS, reduce the investment,reach the simulative goal.
