If the structure of wind turbine generator's drive train model is too simplified, it may not reflect the subsynchronous oscillation (SSO) mode. The types and sizes of wind turbine generator (WTG) are various. Therefore, the parameters of drive train model vary widely. There is an urgent need to study the effects of drive train model's structures and parameters on SSO. In this paper, mass-spring-damping...
A series compensated transmission system and a HVDC transmission system with supplemental subsynchronous damping controller (SSDC) were considered for eigenvalue analysis. Damping conservation is analyzed when series compensation level is varied in a series compensated transmission system. Damping conservation is also analyzed when the gain of SSDC is varied in an HVDC transmission system. In this...
