Abstract :
The method, complex torque coefficient approach, which is used to analyze the sub synchronous oscillation (SSO) problems with the help of PSCAD/EMTDC are recommended. While how to achieve the complex torque coefficient approach by time-domain simulation method effectively has not been specified. With the simulation study of different systems like HVDC system, AC system with series compensation device, etc, amplitude, injection time and additivity of injected oscillating torques are discussed. A set of conclusion to the method is drawn for reference.
