Abstract This thesis presents a control system for a 2MW direct-drive permanent magnet synchronous generator wind turbine system with the objectives to capture the optimal power from the wind and ensure a maximum efficiency for this system.
Angular velocity of the rotor mechanical speed Parameters Configuration Tab Number of phases Select between a three-phase machine model or a five-phase machine model.
This parameter is disabled when the Back EMF waveform parameter is set to Trapezoidal, or when the Rotor type parameter is set to Salient-pole. This parameter is disabled when the Number of phases parameter is set to 5.
Rotor type Select between the Salient-pole and Round, the round cylindrical rotor. This parameter is disabled when the Number of phases parameter is set to 5 or when the Back EMF waveform parameter is set to Trapezoidal.
Select Torque Tm default to specify a torque input, in N.
The machine speed is determined by the machine Inertia J and by the difference between the applied mechanical torque Tm and the internal electromagnetic torque Te. The sign convention for the mechanical torque is when the speed is positive, a positive torque signal indicates motor mode and a negative signal indicates generator mode.
The machine speed is imposed and the mechanical part of the model Inertia J is ignored. Using the speed as the mechanical input allows modeling a mechanical coupling between two machines. The next figure indicates how to model a stiff shaft interconnection in a motor-generator set when friction torque is ignored in machine 2.
The speed output of machine 1 motor is connected to the speed input of machine 2 generatorwhile machine 2 electromagnetic torque output Te is applied to the mechanical torque input Tm of machine 1.
The KT factor takes into account torque units of both machines pu or N. Also, as the inertia J2 is ignored in machine 2, J2 referred to machine 1 speed must be added to machine 1 inertia J1. Select Mechanical rotational port to add to the block a Simscape mechanical rotational port that allows connection of the machine shaft with other Simscape blocks with mechanical rotational ports.
The Simulink input representing the mechanical torque Tm or the speed w of the machine is then removed from the block. The next figure indicates how to connect an Ideal Torque Source block from the Simscape library to the machine shaft to represent the machine in motor mode, or in generator mode, when the rotor speed is positive.
Preset Model Provides a set of predetermined electrical and mechanical parameters for various permanent magnet synchronous motor ratings of torque N.
Select one of the preset models to load the corresponding electrical and mechanical parameters in the entries of the dialog box. Select No default if you do not want to use a preset model, or if you want to modify some of the parameters of a preset model.
When you select a preset model, the electrical and mechanical parameters in the Parameters tab of the dialog box become nonmodifiable unavailable. To start from a given preset model and then modify machine parameters: Select the preset model that you want to initialize the parameters.
Change the Preset model parameter value to No. This does not change the machine parameters. It just breaks the connection with the particular preset model.
Modify the machine parameters as you want, then click Apply. Use signal names to identify bus labels When this check box is selected, the measurement output uses the signal names to identify the bus labels. Select this option for applications that require bus signal labels to have only alphanumeric characters.A Study of Field-Oriented Control of a Permanent Magnet Synchronous Generator and Hysteresis Current Control for Wind Turbine Application THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of the Ohio State University By.
