PSValidate Module

When using measured values, you have to be aware that the measured values are never consistent. Since measurements are always subject to errors, the values will not satisfy the model equations. Basic principles, like conservation of mass and energy, will not be satisfied.

Process engineers often attempt to solve those kinds of problems by identifying “reliable” values and disregarding others. However, this approach is not satisfying since it is time consuming and not repeatable.

Using IPSEpro-PSValidate you have a well defined method that allows you to use all data and to exploit the redundancies of the measured data allowing you to improve your results.

IPSEpro-PSValidate uses statistical methods to eliminate redundancies and to obtain more accurate data. It allows you to:

  • Get the most probable and consistent picture of the state of a process
  • Identify sensor failures
