Abstract

The paper presents the development of a frequency scanning program used for subsynchronous resonance (SSR) screening. The developed program is capable of screening power systems with hundreds of buses. The heart of the program is Z- Bus (Bus Impedance Matrix) of the power system as a function of frequency. The paper describes a fast and efficient method for forming Z-bus. The paper includes validation of the developed program by comparing case results with the IEEE Second Benchmark Model. Frequency scanning results from the application of the program to an existing power system are presented.
