Control and Simulation of a Wind Turbine Generation System

The following project explains the modulation of all different elements that take part in wind turbine of direct-drive technology with a Permanent Magnet Synchronous Generator (PMSG), and the use of the model for the studio and analysis of the control system in a real model turbine, GAMESA 6.0-154. Therefore, it develops a wind speed mathematical model; the power absorbed by the blades of the turbine, one synchronous generator of permanent magnets, a converter back-to-back with an average model modulation and a NPC Three Level Converter modulation, and the electrical grid. With all these elements it has been simulated the entire system performance. This project also gathers the implementation of control strategies that allows the regulation of different variables of the system, as it can be the voltages, currents and power that take part in the system. The main control schemes are the optimal power control and the pitch angle control. In addition, the project has implemented a model, which operates with three parallel converters at the same time, in order to increase the turbine production availability. Finally, the project gathers simulations of the whole system where it shows up the behaviour of their elements and control systems. The simulations are done under different conditions, constant, gust and turbulence wind speed and unstable electrical grid conditions
