Real time simulations of wind turbine with pitch angle control using Fuzzy Logic

In this work, wind turbine pitch angle control using a Fuzzy controller in real time simulation is presented. This controller is implemented in RTDS™ (Real Time Digital Simulator). It was built based on knowledge of operation principles of wind turbines equipped with variable pitch angle control, not requiring mathematical models for this. An alternative for the Proportional-Integral (PI) controllers currently used is presented. The control was developed using CBuilder which is the C program compiler of RTDS™. It was used a Permanent Magnet Synchronous Machine (PMSM) equipped with PI controllers for pitch control. Simulations were performed varying the incident wind speed on a wind turbine equipped with PMSM. These simulations prove the efficiency of pitch control using Fuzzy Logic in real time simulations.
