The induction generator and induction motor are in theory similar, but the ® PrimeLine induction generator has significant differences from standard motors: 1.The emphasis on the PrimeLine® design is to maximize the efficiency with minimum reduction in power factor. 2. Class F varnish is used in place of the class B varnish 3.

The actual speed of three phase asynchronous motor is given by n=n s (1 - s) =120f /p (1-s). It can be seen from the formula that the speed of 3 phase induction motor can be changed by the means of changing the number of induction motor's poles "p", the slip "s" and the frequency of power supply"f". Pole-changing speed control.

This study was conducted to analyze and record the procedures necessary to convert a ten horsepower three phase induction motor into a ten pole three phase synchronous alternator, suitable for use n a wind energy conversion system. It was undertaken in response to the high cost of commercially produced wind energy machines. A search of current literature revealed little in the area of motor or ...

A wind farm is a collection of wind turbines in the same location. Wind turbines are often grouped together in wind farms because this is the most economical way to create electricity from the wind. If multiple wind turbines are placed too close to one another, the efficiency of the

The generated speed information is applied to the frequency converter via the PI control technique and the induction motor is driven according to the reference speed. The purpose of the study is the hardware implementation of a wind energy conversion system for control and online monitoring in a laboratory environment.

The paper describes three-phase and single-phase induction generators which could be used for converting wind energy to electricity. A safety feature of these systems, in comparison with a.c. or d.c. generators, is that if the power line voltage becomes zero, the voltage of the induction generator instantly becomes zero. Connection of a wind-driven generator to a commercial power line is ...
