Voltage and frequency stabilization system with self-excited induction generator

In the paper self-exciting induction generator system has been presented. It has been made on the base of cage induction motor, and it is intended for small hydroelectric and wind power plants. The basic advantages of the system are reliability, simple construction, and durability as well self-service and low cost of production. In the presented solution, generator is not connected with distribution system and represents an autonomous system. For voltage and frequency stabilization purpose its works with AC/DC converter. The paper presents the result of simulation research, as well experimental result obtained on laboratory model of generator with converters and prediction control.
