Generator Testing and Model Development

Testing and Model Validation Services


To be able to conduct dynamic analysis of a power system, and to properly tune controls, it is first necessary to develop good models for all generators and their associated controls. Very often, models provided by manufacturers are inadequate or actual controls in the field have been modified and no longer are accurately represented by existing models.

To obtain accurate models, it is necessary to conduct some field tests from which the models can be derived. Simulations can then be used to validate the models against the actual field measurements.

Powertech has extensive experience in conducting steady-state and dynamic tests to establish key system information including,

  • Generator parameters
  • Excitation system parameters including power system stabilizers
  • Speed governing system parameters
  • Reactive power capability
  • Protection performance

Powertech will work with you to develop a detailed test plan. To minimize unexpected results during the field testing process, pre-test simulations will be conducted when possible, to predict the expected outcome of the field tests. Powertech will then visit the plant to execute the test plan, with the cooperation of plant operators.

From field test results, computer models are developed and their performance checked against the measurements using simulations. Using advanced analysis tools, simulations can be performed to study individual plant performance as well as the performance of the full interconnected system. Optimum control settings can then be determined.

Powertech has tested and modeled hundreds of generating units of all types and sizes. Contact us today to discuss your testing and modeling requirements.
