摘要：Development of a dynamic model covering a large power system and suitable for analyses of inter-area oscillations often requires the use of typical system component models used in tran- sient stability analyses.This may consequence in very optimistic results,i.e.much better oscilla- tion damping than actually recorded in the system.This was seen in the 1990s,when in the USA and Canada (Western Interconnection) weakly damped inter-area oscillations were observed, which could not be correctly reflected using standard dynamic models.The paper analyses selected system component modelling simplifications due to the use of generic models that may affect the damping of inter-area oscillations.The degree of this impact on the results is shown in a dynamic model covering the synchronously operated part of the continental Europe system.
