Abstract

A novel variable-speed cascaded induction generator system is proposed for small-scale hydroelectric power plants, in which the second induction generator has double three-phase stator windings (or six-phase windings). The proposed low-cost system can provide a brushless, robust structure and less distorted currents without using an expensive PWM rectifier on the machine side and an expensive adjustable-blade water turbine. The simulated results showed that the system has sufficient capabilities for practical use.
