Abstract

A system for generating electricity, the system comprising: a turbine having at least one blade coupled to a rotatable shaft, wherein the at least one blade is configured to convert kinetic energy received from a fluid flow into rotational energy within the shaft; a variable-speed generator coupled to the rotatable shaft and configured to transform rotational energy received from the shaft into electrical energy; and a control unit configured to: continuously predict the speed of the fluid flow based on the rotational speed of the turbine and the amount of electrical energy being generated by the generator; and regulate the amount of electrical energy generated by the generator such that the rotational speed of the turbine is maintained within a predetermined range that is based on the predicted speed of the fluid.
