Precise modelling, reliable validation:
Prerequisite for a safe operation.

 

In order to ensure a safe and reliable future operation, energynautics thoroughly tests energy generation concepts using the latest tools and scientific knowhow. Modelling is carried out, for instance, using Matlab/Simulink and DIgSILENT Powerfactory and comprises, among others, the following areas:

  • Modelling Combined heat and power station:
    • A detailed modelling of a voltage and speed governor.
    • On a higher level, there is a controller for active and reactive power that provides the set point for the voltage and speed governor.
    • There exists an option to switch between different operating states, e.g. load share of power station blocks or base-load operation.
  • Modelling Wind turbines:
    • We model two-mass spring damper systems – this is very important for the simulation of the wind turbine's effect on the power network.
    • Drive concepts may consists of asynchronous or synchronous generators with or without converter.
    • Depending on the version, we will model a capacitor bank with reactive power control.
  • Validation:
    • In order to validate the models, we compare them with measured data and – if necessary – adapt the parameters.
    • We carry out system identifications where the CHP plant or the wind turbine is connected to an intermittent load and exposed to a number of load steps.
    • It is also possible to use measurements from an ongoing operation in order to carry out the comparison and to fine-tune the models.
