For the development of the research project, the scientific and methodological literature is analyzed in order to determine the state of the art of the configurations and control models used in wind generators. As a result, the type D configuration is used, because it has a greater efficiency for the Wind Energy Conversion System (WECS), based on a permanent magnet synchronous gadget (PMSG) by direct drive, a back to back control that counts with a rectifier and inverter powered by IGBT´s, connected through a direct current capacitor. The active power control is carried out by the generator side, by means of the maximum power coefficient, in the study carried out a control pitch angle is used, where the maximum power delivered by the turbine is obtained with a betha value of 0 degrees. Meanwhile the control of reactive power, voltage and frequency is done on the network side, for which different types of controls, called voltage control oriented or VCO, both for voltages and currents with DC values in a stationary reference system, it also has a PLL control that keeps the phase angle value synchronized with the grid voltage, in addition to an INNER LOOP control capable of varying the inverter's output currents and finally next to the OUTER LOOP control that delivers reference currents to control the active and reactive power to the network, demonstrated the effectiveness of the control strategy proposed in theory. |
