Subsynchronous Resonance Analysis

SSR is an add-on module to SSAT that provides an easy-to-use interface to systematically perform subsynchronous resonance (SSR) analysis of a power system in frequency domain.


  • Based on frequency scan technique and modal analysis method
  • Identification of network resonance frequencies
  • Identification of generators interacting with network dynamics
  • Identification of interactions between network dynamics and control systems of wind turbine generators
  • Determination of possible SSR frequencies and damping
  • Analysis of system with different levels of compensation for transmission lines
