| Abstract: |
| The expressions of damping torque for a single-machine infinite-bus system are derived firstly,in which the effect of load characteristics on low frequency oscillation is analyzed theoretically.For a concrete example,the electromechanical oscillation modes are resolved and validated by the dynamic simulations using Matlab software. |
| Key words: load characteristics,damping torque,low frequency oscillation,Matlab,dynamic simulation |
