1.Draw and label a typical generator capability curve,
showing the Rotor Current limit, stator current limit and the
origin of the Rotor Current circle. Also include the prime mover
limit.
2. Write down and explain the important formula and relevant
current, voltage and Power limit. Show the correct axes of the
curve. Indicate the safe operating point for the generator on the
curve.
It defines the boundary within which a generator can deliver reactive power continuously without heating.
Their ratings are specified in MVA and power factor at a maximum terminal voltage.Active power delivered by generator is only limited by power delivering capability of turbine.
All the diagram and curve are drawn below and labelled properly ,the expression for limit and armature limit are also shown below.
