Contents
1. USER MANUAL OF THERMAL POWER PLANT TPP SIMULATOR SOFTWARE This is the manual for Thermal Power Plant TPP Simulator laboratory exercise The manual consists of useful information about simulator software which helps the user to get familiar with software interface operation and functions It is highly recommended to read the manual before start to work with the simulation exercise as well as to print it out and have it available during the simulation Table of contents The mouse Keyboard function keys Initial conditions Picture directory Run amp freeze simulation Snapshots Simulator help menu Pop up windows Process pictures 10 Variable lists 11 Malfunctions 12 Description of pictures 13 Description of symbols 14 Simulator speed ratio 15 Alarm system 16 Instructor help 17 Exit the simulator software OMONAARWN gt 1 The mouse two bottoms Left button open valves start pumps Right button close or stop Mouse over shows information about valves pumps 2 Keyboard function keys Present windows layout Shift F8 F10 F11 Home Shift Home Page up Page down Run simulation Freeze simulation Stop the simulation and exit the application Snapshot Replay Operating condition Recall picture Initial condition Alarm log Page acknowledge Alarm Variable list Alarm list Picture directory Select picture Previous picture Next picture Download keyboard layout PDF 3 Initial c2. onditions Initial Conditions is a description of a specific situation Loading an initial condition exercise implies that you together with the model itself also load a set of parameters that describe the starting point of your simulation To reach a specific training objective the instructor normally needs to modify the Initial Condition If you change the value of one of the above mentioned variables and store it you have in fact created a new Initial Condition It is possible to change the variables define new initial concision and save it An Initial condition must be chosen prior to starting the simulation Snapshots can be converted to initial conditions too 4 Picture directory e Press Home key to get Picture Directory e Select one of the options and view Process Display 5 Run amp freeze simulation Run To set the simulator in Run mode press the Run pushbutton F1 The indication in the header bar changes from Freeze to Running indicates that the simulator is in Run mode The simulated time displayed in the header bar of the display starts incrementing Freeze To set the simulator in Freeze mode press the Freeze pushbutton F2 on the keyboard The mode indication in the header bar changes from Running to Freeze The simulated time displayed in the header bar of the display stops incrementing 6 Snapshots A snapshot is a copy of all the variables and parameters needed to describe the state of

5. the simulator A snapshot consists of one or more binary files stored on the system hard disc and can be seen as a picture of the simulated plant state at a given time Snapshots will only exist during a training session and cannot be transferred to or used in later training sessions unless they are converted into initial conditions A snapshot is marked with the simulated time when it was taken and is identified by this time mark There are two ways to take snapshots automatically or manually Automatic snapshots Snapshots are taken automatically when setting the snapshot interval Default snapshot interval at simulation start up is 00 00 i e no snapshots taken automatically However setting the snapshot interval to 00 10 will cause snapshots to be taken at 10 minutes intervals Manual snapshots To force a snapshot to be taken independently of the set snapshot frequency press the Snapshot pushbutton This permits the saving of situations not captured by the automatic snapshot feature Snapshots saved using the auto snapshot facility are most often used for this purpose Up to 100 snapshots may be saved and are thus accessible from the snapshot directory during a training session Snapshots are used for 1 Creating initial conditions 2 Performing a replay 3 Do a backtrack 7 Simulator help menu The simulator includes a help system At the bottom of right corner there is a help function button which gives clea
