Abstract: The invention provides methods and systems for real-time monitoring of the insulation state of wind-powered generator windings comprising the following steps: a) capturing in real-time, during a predetermined time period (in situations where the generator is synchronized to the electrical network but is not yet couplet thereto as well as in situations where the generator is producing energy) the values of one or more electrical and vibration variables of the generator; b) obtaining in real-time, the temporal evolution of the vibration and of the inverse components of electrical variables at one or more predetermined frequencies; c) identifying a possible generator insulation fault when the inverse component of at least one electrical variable and/or one vibration at a predetermined frequency exceeds an absolute threshold or a temporal increase threshold pre-sets.

Abstract: A joining device of a metal segment to a concrete segment of a hollow tower. The joining device is formed by a set of bolts passing by one of its ends by holes of an anchoring ring and attached to its both sides by a first set of nuts and arranged to be attached by its other end to the base of the metal segment by a second set of nuts. The anchoring ring includes a set of connectors extending externally and internally thereto in a substantially perpendicular direction to the bolts and arranged so do not interfere with reinforcement. The invention also refers to a hollow tower comprising at least one metal segment joined to a concrete segment by the joining device.

Abstract: Control method for a wind farm connected to a power grid (1) and comprising a plurality of generating units (2). The presence or absence of a voltage disturbance in the grid (1) is determined with the method, and when the presence of a disturbance is determined, the generating units (2) are controlled during said presence so that they generate the required power and the wind farm (100) thereby participates in stabilizing the grid (1). Furthermore, in the method, when the disappearance of said disturbance is determined, the required power continues to be generated with the generating units (2) for a limited time interval in order to provide a smooth and controlled transient until the voltage of the grid (1) stabilizes. Wind farm connected to a grid (1) and comprising a plurality of generating units (2).

Abstract: The invention provides a three phase medium voltage power conversion system for coupling a power source to a utility grid comprising a power converter and a Notch-Filter. The switching control system of the inverter of the power converter is based on SHE-PWM patrons. The Notch-Filter is tuned to attenuate the frequency of the first harmonic that the switching control system of the inverter cannot attenuate and configured with damping means capable of smoothing the resonance frequency without affecting the notch frequency.
