“…The three inverter drive modules share the same speed controller which provides the same current commands for the independent current controllers. Owing to the segregated windings and independent drives, the risk of fault propagation among different 3-phase sets is minimized [23]. Furthermore, any failure in a single 3-phase set does not significantly affect the operation of other modules.…”

“…The time elapsed between fault occurrence and triggered safety device is about one third of a second. If there is a short circuit between turns of the same phase the time elapsed between incipient fault and triggered safety device is about several minutes or even much longer, depending on the stator winding method [9]. This may give enough time for fault detection and adequate autonomous reaction provided by control system to suppress the fault from further spreading on other generator and wind turbine components.…”

“…Focus of this paper is to research and develop a faulttolerant control strategy for stator winding isolation faults that cause about 30% of machine faults [6][7][8][9][10][11] and are common for both asynchronous and synchronous machines used in wind turbines (doubly-fed induction generator, squirrel-cage induction generator, synchronous generator with wound rotor, synchronous generator with permanent magnets). A modulation of the generator flux using already available control system is introduced in order to suppress the fault propagation and to keep the electrical energy production possible under emergency circumstances.…”

Original scientific paperFaults of wind turbine generator electromechanical parts are common and very expensive. This paper introduces a generator fault-tolerant control scheme for variable-speed variable-pitch wind turbines that can be applied regardless to the AC generator used. The focus is on generator stator isolation inter-turn fault that can be diagnosed and characterised before triggering the safety device. An extension of the conventional wind turbine control structure is proposed that prevents the fault propagation while power delivery under fault is deteriorated as less as possible compared to healthy machine conditions. Fault-induced and inherent asymmetries of the generator are estimated and respected by the field-oriented control of the generator to eliminate torque oscillations. An approach for asymmetry detection based on an unscented Kalman filter is proposed. Presented fault-tolerant control strategy is developed taking into account its modular implementation and installation in available control systems of existing wind turbines to extend their exploitable life span and increase energy production. Simulation results for the case of a megawatt class wind turbine are presented.Key words: Wind turbine control, Generator fault-tolerant control, Stator winding isolation fault, Nonlinear estimation, Asymmetric field-oriented controlUpravljanje vjetroagregatom otporno na me uzavojske kvarove statorskog namota generatora. Kvarovi elektromehaničkih dijelova generatora vjetroagregatačesti su i izrazito skupi. U ovom radu predstavljen je koncept na kvarove otpornog upravljanja generatorom vjetroagregata s promjenjivom brzinom vrtnje i zakretom lopatica primjenjiv bez obzira na tip korištenog izmjeničnog generatora. Naglasak je stavljen na oštećenje izolacije unutar namota jedne faze statora generatora koje se može dijagnosticirati i okarakterizirati prije aktiviranja sustava zaštite. Predložena je nadogradnja postojećeg sustava upravljanja vjetroagregatom koja sprječava širenje kvara i pritom postižečim manje smanjenje proizvodnje električne energije u odnosu na normalan režim rada. Tako er je prikazano vektorsko upravljanje generatorom koje uzima u obzir nesimetrije generatora, kako one nastale uslijed djelovanja kvara, tako i one inherentne. U radu je prikazan pristup za otkrivanje nesimetrija generatora zasnovan na nederivacijskom Kalmanovu filtru. Predstavljena strategija upravljanja razvijena je uvažavajući mogućnost modularnog nadovezivanja na postojeće algoritme upravljanja već postavljenih vjetroagregata s ciljem produženja njihova životnog vijeka i povećanja proizvodnje energije. Dani su simulacijski rezultati za slučaj vjetroagregata iz megavatne klase.Ključne riječi: upravljanje vjetroagregatom, upravljanje otporno na kvarove generatora, kvar izolacije statorskog namota, nelinearna estimacija, vektorsko upravljanje nesimetričnim strojem

This article presents a survey on actuation systems encountered in offshore drilling applications. Specifically, it focuses on giving a comparison of hydraulic and electric drivetrains along with detailed explanations of their advantages and drawbacks. A significant number of industrial case studies is examined in addition to the collection of academic publications, in order to accurately describe the current market situation. Some key directions of research and development required to satisfy increasing demands on powertrains operating offshore are identified. The impact of the literature and application surveys is further strengthened by benchmarking two designs of a full-scale pipe handling machine. Apart from other benefits, the electrically actuated machine reduces the total power consumption by 70 % compared to its hydraulically driven counterpart. It is concluded that electric actuation systems, among other advantages, in general offer higher efficiency and flexibility, however, in some specific applications (such as energy accumulation or translational motion control) hydraulic powertrains are favorable.
