Synchronous Generator Inertia Constant Testing
Validation of the inertia constant of a synchronous generator

Hello everybody,

I want to validate the inertia constant of a synchronous generator, stated by its supplier.

I have all the necessary instruments to study the behaviour of the generator including oscillo-perturbography recording devices.

I've read somewhere that one typical test is to perform a load reject of the generator by disconnecting it from the grid and studying the df/dt slope.

I need your help to decide the best testing procedure. I can perform load reject or load acceptance tests.

T think that if I choose a load acceptance test, the generator inertial response will depend on the response of all the other generators on the grid.

Am I right?

I am looking forward to hear your expert advices.

Best regards.
