Application of Induction Generators in Power Systems

摘要

The application of induction generators in power systems is the subject of this report covering an EPRI sponsored research project RP-1945-1. The performance of induction generators as function of machine and system parameters and as function of war source control is evaluated and compared with that of synchronous generators. Results are presented so as to allow identification of system conditions favoring the application of induction generators and to estimate war source requirements. The study covers fundamentals of induction generator transient behavior and determinations of the effect of modeling detail. The importance of rotor flux transient effects in high efficiency (low slip) designs is demonstrated. Although the thrust of the investigations was to explore application of large scale induction machines (500 to 1000 MVA) the range of parameters studied and their presentation in normalized form allows the results to be applicable to all sizes of machines.
