Power Plant Simulator & Designer ( PPSD ) is a commercial software from KED GmbH for the modeling of thermodynamic processes and steam generators . PPSD is mainly used in the calculation and design of steam generators and power plants.
Emergence
The software was developed in 1993 by Grigory Doverman, Ivan Turovsky and Christian Daublebsky von Eichhain as a training simulator for power plants on a PC-DOS basis with a graphical user interface. The program was later changed to include the design of steam generators and heat exchangers , and subsequently expanded to include entire power plants .
commitment
PPSD is used for the design and recalculation of various steam generators with natural circulation , forced circulation boilers and once-through boilers with subcritical and supercritical pressure . It can also cycle power plants , cogeneration plants , gas and steam combined cycle power plants , waste incinerators and Organic Rankine Cycle are designed and calculated. In newer versions, components for calculating absorption chillers to support flue gas condensation have also been added. The program is also used to investigate high-temperature corrosion in waste incineration .
functionality
The various components are symbolized by icons on the graphic surface (e.g. turbines , evaporators , condensers , ...) and these are linked with each other. PPSD has 66 different components and many different one- and two-phase working fluids e.g. B. heat carrier , water vapor , exhaust gases , which the user can also add and change. There is also a comprehensive database for various fuels such as coal , natural gas and oil . Extensive equations for calculating heat transfer and pressure loss as a function of thermal and geometric data are programmed in many components . All equations in the model are solved iteratively . During the iteration, the various material data z. B. Water-Steam Table IAPWS-IF 97 used .
The various components can be supplemented and changed with a script language , a Visual Basic Script script language is used. By using the object-oriented Visual Basic script language, the scripts can easily be transferred to other components. The users can use various interfaces such as B. spreadsheet programs , Visual Basic for Applications for external control from Excel or with Java or C ++ programs from the operating system level. With the option of external calls, PPSD can also e.g. B. be coupled with a process control system.
Calculation modes
PPSD includes various calculation modes. In "Design" mode, the geometry and process target values specified by the user are used to calculate a design point. In "Partial Load" mode, the partial load behavior of the steam generator and the steam turbine is determined based on the values calculated in "Design" mode , e.g. B. pressure , efficiency . In the "Dynamic" mode, unsteady processes such as B. starting processes, load changes, emergency shutdown, etc. can be calculated as a function of time. To do this, the user must enter the energy input as a function of time, valve running times, PID controller values, etc.
Interfaces
With the help of the COM interface, the user can access and write all values from an external program. This is particularly useful for use in a process control system for e.g. B. Sootblower control is important.
