This paper presents a design model for a hybrid braking mechanism (electrical-mechanical) to generate an electromagnetic force as a result of the electric current flow and convert it into a frictional force that generates a braking torque to stop the turbine shaft rotation. And using MATLAB program to code for the braking system of large wind turbines in general when excessive speeds occur. By damping the rotational speed of the generator to maintain the standard rotational speed until reaching the critical rotational speed, the system stops the rotation completely through the electromagnetic braking mechanism. To give three outputs in the form of curves, where the first output represents the relationship of wind speed with generator capacity, turbine capacity and braking capacity, and the second output represents the relationship of wind speed with generator torque, turbine torque and braking torque, and the third output represents the relationship of wind speed with the electric current required for the process of braking and stopping. And comparing the ideal theoretical results with the practical results of this model.
