Validation of power plant performance

Validation of the power plant performance primarily comprises testing of governor and excitation system response. Protrol has elaborated a state-of-the-art plant test equipment based on in-house developed hardware and software with validated performance from both laboratory testbench setups and on-site tests. The test method supports both open-loop and closed-loop verification of controllers and equipment.
