Abstract

This paper presents new techniques to improve the accuracy and velocity for the modeling of synchronous machines in stability and transient studies. The proposed model uses frequency responses as input data, obtained either directly from measurements or calculated from the available data. The new model is flexible as it allows changes in the detail in which the machine can be represented, and it is possible to partly compensate for the numerical errors incurred when using large integration time steps. The model can be used in transient stability and electromagnetic transient studies as secondary arc evaluations, load rejections and subsynchronous resonance
