| Summary: | In order to improve the efficiency of analysis for subsynchronous stability of power systems, a quick analysis method based on the complex torque coefficient approach was proposed With the lack of mechanical damping data in engineering practice, this paper just adopted the stability criterion of electric damping The IEEE first benchmark model was built by PSCAD/EMTDC software, and the author analyzed characteristics of the traditional complex torque coefficient approach and its early optimization method on the basis of the model And then an improved analysis method combining the frequency scanning method with test signal method was proposed After changing the parameters of the IEEE first standard model, the author analyzed the subsynchronous stability of the systems featuring different stability respectively with the quick analysis method Finally, the author verified the analysis results in combination with time domain simulation Through experiments, it is shown that the quick analysis method is more timely than the complex torque coefficient approach in analysis for subsynchronous stability |
