hydropower plant and especially micro-hydropower plant is an available, reliable and economical energy source. micro-hydropower plant is one of the most environment-friendly technology, use and development of which leads to reduction of energy consumption sporadically and worldwide. along with the growth of these power plants, the issues related to the control of electrical parameters such as l...

This paper presents a control strategy for a grid connected doubly fed induction generator (DFIG)-based wind energy conversion system (WECS).Control strategies for the grid side and rotor side placed in the rotor circuit of the Doubly Fed Induction Generator (DFIG) are presented along with the mathematical modeling of the Wind Energy Conversion System. In this control approach, wind generators ...

This article proposes a cascade proportional-integral second-order sliding mode control (PI-SMC) method for matrix converter-fed brushless doubly fed induction machine (BDFIM). The PI-SMC consists of PI speed controller with an inner-loop (SMC). provides reference to the SMC constraints according system requirements in terms maximum current and speed. As discontinuous sign function traditional ...

Experts theorized that a Brushless Wound-rotor [Synchronous] Doubly-fed Electric Machine System (BWRSDF), which can symmetrically motor or generate with variable speed, provides higher efficiency, higher power density, higher torque density, and lower cost than any other electric machine system, including the permanent magnet electric machine system, but only with the discovery of a practical b...

A smart pitch control strategy for a variable speed doubly fed wind generation system is presented in this article. Nonlinear as well as linearized dynamic models of the wind system pitch controller and the doubly fed induction generator including the drive train are developed. A PI controller is employed to generate the appropriate pitch angle for varying wind speed conditions. An adaptive art...
