The project details the modelling of the induction motor SEL701 Relay in PowerFactory. In order to prove operational reliability, both off-line and on-line testing were implemented to verify the characteristic curve of the relay by measuring trip times. Prior to modelling the relay, the thermal limit curves of the motor were studied to scheme the motor protection relay. In addition, the requirement of motor protection is discussed and the elements of a protection relay corresponding to the requirements are presented. The results indicate that the off-line (simulation) and on-line test have consistent outcomes.
