ABSTRACT
This chapter deals with the most ordinary applications of induction generators. Such applications are usually based on the variable speed features of the induction generator, which enables the control of a wide set of variables such as frequency, speed, output power, slip factor, voltage tolerance, reactive power, and others. In its variable speed operation, an asynchronous link (dc link) is usually interposed between the generator and the load or network to which the power is being delivered. The simplest application of the induction generator is its direct connection to a grid, which is sufficient to guarantee the electrical rotation above the synchronous to control a scheduled power flow. Stand-alone applications are also common in cases of low levels of power generation. In all these cases, a well-designed speed control or speed limiter is mandatory for good results.
