The paper describes a frquency domain technique for the controller
design and stability analysis of multi-machine power system indud& a
superconducting genertor (SCG). An equivalent model for each generator is
obtained, taking into account the dynamic interaction between units, and is
used as a base for controller design, the air-cored nature of the SCG and its
very long field time constant renders that the governor control is to be
considered only. The design technique enables the controller designers to
add the required phase at the machine electromechanical frequency,
ensuring a satisfactory transient response and prevent the possibilities of
system failure.
