Synchronous and asynchronous generators frequency and harmonics behavior after a sudden load rejection
This paper describes load rejection tests, done at two hydro power plants in Sweden, one equipped with synchronous and the other with asynchronous generators. During the tests voltages and currents are digitized, recorded and thereafter off-line processed. By this, in the processing of distorted and fast parameter-varying voltages and currents the powerful estimation technique, the Newton type alg
