A practical measuring method of subsynchronous oscillation(SSO)damping was promoted to monitor the damping of SSO online.The new method can be easily realized on a computer
which consists of an intelligent fault detect algorithm and a real-time damping calculation algorithm.The real-time SSO damping monitoring system was applied in some power plants.The application results show that
this device can calculate the system damping real-time and evaluate the inhibition effect of subsynchronous inhibition equipment
which can provide more accurate parameters for the SSO simulation.
