Simulation of Induction Machinery for Power-system Studies

A simple, fast, and accurate algorithm for determining induction-machine transient behavior is presented. The differential equations for the full-order model of induction machines are simplified and solved using linear system techniques. Examples show that the algorithm is accurate for large disturbances and requires as little as 29% of the CPU time required by the full-order model. The algorithm may offer computational advantages in some studies of large-scale power systems where the detailed induction machine models can not be used due to the complexity of the overall system and where the overall CPU time may be costly
