    摘要: A method for discovering demagnetisation faults of a permanent magnet synchronous generator, such as a wind power generator. The method is performed during operation of the synchronous generator and includes measuring the vibration of the stator, performing a frequency analysis of the vibration, and deducing whether the generator suffers from demagnetization of a permanent magnet, from the vibration analysis. Moreover, geometric eccentricity faults and electric short circuit faults may also be detected from the vibration.

    摘要: The present invention relates to a grid monitoring system, in particular a grid monitoring system enabling real-time monitoring of grid variables, e.g. voltage and current, in electrical power systems, such as single or three-phase networks. The grid monitoring system comprises a harmonic detection unit being adapted to subtract harmonics of an input signal before feeding the input signal to a plurality of signal generators in the harmonic detection unit.

    摘要: This invention deals with an advanced Real-time Grid Monitoring System (RTGMS) suitable for both single-phase and three-phase electric power systems. This invention provides an essential signal processing block to be used as a part of complex systems either focused on supervising and diagnosing power systems or devoted to control power processors interacting with the grid. This invention is based on a new algorithm very suitable for real-time characterization of the grid variables under distorted and unbalanced grid conditions. The main characteristic of this invention is the usage of a frequency-locked loop, based on detecting the grid frequency, for synchronizing to the grid variables. It results in a very robust system response in relation to existing technique based on the phase-angle detection since grid frequency is much more stable variable than the grid voltage/current phase-angle, mainly during grid faults. Moreover, the algorithm supporting this invention is very efficient and can be implemented in regular industrial microprocessors. These features make the RTGMS object of this invention ideal to be applied in the control of distributed generation systems (DGS), flexible AC transmission systems (FACTS), power quality conditioners (PQC) and uninterruptible power supplies (UPS). In all these systems, the fast and precise real time detection of the voltage and/or current sequence components under grid fault conditions is a crucial matter.

    摘要: Flavoured/aromatized ice cubes, a method for their production and the use of the ice cubes produced. The cubes are characterized in that each cube comprises an ice cube mass formed by frozen water with flavouring (and optionally colouring) agents in variable proportions of substantially between 0.01% and 20% by weight of the mass of water to be frozen, for the compensation of the flavour (and optionally the colour) of a drink cooled by the introduction of the ice cubes in a manner such that the flavouring (and optionally colouring) agents are dissolved in the mass of the ice cubes or are incorporated in the cubes in the form of discrete bodies soluble in the liquid to be cooled.
