  • Ability to remain in synchronism.
  • Small disturbances or changes which are expected.
  • Machine rating constraints
  • Rate of change of power wrt delta
  • Study Period: More than 1 s

  • Large Disturbances 
  • Fault Analysis
  • Rate of change of delta wrt time
  • Within 1 to 1.5s
  • Also called as initial swing

  • Kinetic Energy Storage Consideration
  • Mechanical to Electrical Domain Conversion
  • Equating GH= Kinetic Energy Storage in terms of Moment of Inertia
  • Take care of angles (Radian / Degree??)
  • M=GH/pi*F
  • M=GH/180F
  • Per Unit System , Divide by G

  • Basic Equation of Supply Demand Balance
  • Balancing in Machine Mechanical and Electrical torque is considered.
  • Step I: Torque Balance
  • Step II: Multiplication by Mechanical Rotational Speed
  • Conversion of Mechanical to Electrical
  • Representation by M
  • Conversion of Theta to Delta
  • This is Single Machine Equation
  • For multimachine (Consider 2 Machines)
  • Add the individual Swing Equations by considering rating and base power
  • Express addition again in terms of swing equation format.
