Determination of the optimal operational energy zones and the mathematical models for wind power plants

The present paper analyzes the operation of the wind energy system, consisting of a wind turbine, a synchronous generator with permanent magnets (SGPM) at time variant wind speeds. Capturing the maximum wind energy is a complex problem, difficult to solve in practice when the speed varies and over time and the mechanical inertia of the wind turbine is high, not allowing the generator speed to be optimally energy-efficient. The paper contains two distinct parts: 1st determining the power at the wind turbine for a given wind speed and 2
^nd
periodically determination of the mathematical model of the wind turbine (MM-WT). Those two issues are solved by measuring the main functional sizes: mechanical angular speed, wind speed, and electric energy.
