Experimental determination of the parameters for a salient rotor synchronous machine with and without pole screens

This paper investigates simulation models for salient pole solid rotor synchronous machines through experimental model identification. Two different methods are used, the classical stand-still frequency response test method and the more recent prediction error method. The results are compared and analyzed. It is shown that a third order model is required to describe the machine dynamics accurately. Further, the impact of extra copper pole screen is investigated, and it is concluded that these could have a beneficial effect with inverter supply.
