The induction generator effect (IGE) and the open-loop modal proximity (OLMP) are two different reasons why sub-synchronous oscillations (SSOs) in a series-compensated power system (SCPS) may occur. The IGE attributes the growing SSOs to negative resistance. while the OLMP explains the SSO mechanism from the standpoint of modal conditions.
