Abstract

This master project is focused on the dynamic performances of wind generators based on PMSG (permanent magnet synchronous generators) connected to the network in fault condition and network disturbance. Permanent magnet machines have many advantages over other popular configurations used by major manufacturers of large wind turbines. They are characterized with multi-magnetic poles, as a result, low rotational speed generators can be manufactured with relatively small sizes with respect to their power rating. Moreover, gearboxes can be omitted due to low rotational speed possibility in PMSG. However, the impact of this type of wind generators in the network should be minimized improving the operate conditions at the connection point of the wind farm. Thus, this project investigate ways to reduce negative impacts as loss of system stability and voltage fluctuation at the connection point of wind farm equipped with permanent magnet synchronous generator (PMSG). Simulations of symmetrical and unsymmetrical faults will be performed by using (PSCAD and ANATEM), in which the PMSG and his controllers will be implemented by computational models. (AU)
