Title: Induction generator modeling and relaying

Abstract

Consideration of the world's energy needs and environmental concerns have encouraged wind and solar power sources. An increasing number of relatively small induction generators are being connected to the power grid at the distribution level. There is need to study the transient and steady-state behavior of the induction generators and their relaying. There is a concern of induction generator islanding, which may impede its further application. Induction-generator mathematical models in the arbitrary reference frame with saturation, and system models in the stationary reference frame, which include a grounded wye-grounded wye or grounded wye-delta transformer, a transmission line, and with load and capacitance compensation, are derived. Using these models, abnormal situations both at the machine terminals an don the high voltage side of the transformer were simulated on a mainframe computer. These included line faults, lines open and reclosing, induction generator islanding, rapid changes in voltages and frequency. Constraints in the stationary reference frame for the above abnormalities are derived. The simulations revealed a phenomenon: the induction generator accelerates upon asymmetrical faults.
