Industry-common Simulation Model for Waterway/Turbine/Turbine Regulator

For synchronous production units connected to the grid EU (Requirements for Generators, RfG) has put requirements on the frequency response capabilities. These requirements are fulfilled by use of LFSM and FSM functions in the turbine regulator. Fulfillment of the requirements are shown by computer simulations as well as physical tests on the production unit.

Also, to participate with auxiliary services as FCR-N and FCR-D, prequalification tests have to be performed, to show that stability and performance requirements are fulfilled. Even if simulations are not a part of the prequalification process, computer simulations can help the asset owner to speed up the process and optimize the unit.

Simulations, as mentioned above, require a simulation model with sufficient functionality and accuracy to be useful. When it comes to hydropower production units, there is a lack of standardized simulation models of the waterway, turbine and turbine governor that are useful.
This project will focus on the development of such a simulation model. By combining theoretical investigations and extensive testing in hydropower stations a basis for a simulation model is achieved.

The goal is to develop a simulation model with adequate functionality and accuracy to show fulfillment of the RfG requirements and auxiliary services as FCR-N and FCR-D.

Both Francis and Kaplan turbines are targeted. The model will be accompanied with a guide to find the necessary data for model parameters from rated data and tests.
