    摘要: An apparatus for controlling a thyristor controlled series capacitor connected to a power transmission line. A thyristor firing control includes a unit for effectuating a desired capacitor voltage zero crossing in dependence of a line current and a capacitor voltage in response to a command signal. A command control provides the command signal to the thyristor firing control. The command control includes a damping control including a damper configured to damp at a least one discrete frequency.

    摘要: Un système de commande de déclenchement destiné à un fonctionnement vernier sûr d'un condensateur (TCSC) (30) commandé par thyristor en série avec une ligne de transmission (24) utilise un déclenchement à phase commandée basé sur la tension contrôlée du condensateur et sur le courant du secteur. Le fonctionnement vernier du système TCSC (20) est assuré par prédiction d'un angle de déblocage survenant pour commuter le circuit de commutation (32) afin de faire passer une impulsion de courant de dérivation du thyristor. L'impulsion de courant produit une composante de tension de décalage alternatif au niveau du condensateur en série (30), en plus de la composante de tension normale, chaque impulsion de courant modifie la tension du condensateur proportionnellement à la valeur intégrée de l'impulsion de courant. Le système TCSC (20) répond de manière prompte à une commande de décalage provenant d'une unité de commande à plus haut niveau (86), et il commande avec précision le travail sur les thyristors de dérivation (36a, 36b) afin de réduire au minimum les dommages causés aux thyristors, et empêche la dérive de la tension des condensateurs en lui interdisant de s'éloigner d'une valeur consigne désirée lors des perturbations sur le courant de secteur.

    摘要: Thyristor-controlled series capacitor equipment (CEQ), intended for connection between an ac network (NET) and a converter (CONV), connected thereto, for conversion between alternating current ((IT) and high-voltage direct current (Id), with a controllable semiconductor valve (TYSW), has control equipment with control means (32) which, in dependence on a synchronization signal (ΖSYNC), form firing pulses (TP1,TP2) for control of the semiconductor valve. The converter has a control device (CTR1) which forms a control-angle order (α-ORD) for phase-angle control of the converter, related to the phase position for a voltage (UJ2) at a chosen connection point (J2). The control equipment (CTREQ) comprises phase-correcting means (52, S4) which form the synchronization signal in dependence on a voltage-phase signal (ΖU)) supplied thereto and containing information about the phase position of said voltage, and on a control-angle signal (α) supplied thereto and containing information about the control angle of the converter.

    摘要: A subsynchronous resonance mitigation system (20, 200, 300, 400), including a method and apparatus, for damping undesirable subsynchronous resonance oscillations in a generator (208, 210), which, if left unchecked, may damage the shafts of a turbine-generator set. A remote coupling apparatus, such as a thyristor controlled series capacitor (TCSC) system (30, 34 and 35), a sourced inverter device (302), or a static phase shifter (420), is coupled to the generator (208, 210) by a transmission line (24, 204). In response to a firing command (48, 310), the coupling apparatus introduces subsynchronous resonance mitigating currents into the transmission line (24, 204). Sensors (44, 222, 237) monitor power line parameters and/or the generator speed, and in response thereto, a higher-level controller (86, 220) generates a voltage command (85, 308). A vernier controller (50) responds to the monitored power line parameters and the voltage command (85, 308) to provide the firing command (48, 310) to the coupling apparatus.

    摘要: Système d'atténuation de résonance sous-synchrone (20, 200, 300, 400), comprenant un appareil utilisé selon un procédé permettant d'amortir des oscillations de résonance sous-synchrone indésirables dans un générateur (208, 210), ces oscillations étant susceptibles d'endommager les arbres d'un ensemble générateur-turbine si elles ne sont pas contrôlées. Un appareil de couplage éloigné, tel qu'un système de condensateur en série commandé par thyristor (TCSC) (30, 34 et 35), un dispositif inverseur de source (302), ou un déphaseur statique (420), est couplé au générateur (208, 210) par une ligne de transmission (24, 204). En réponse à un signal de commande de déclenchement (48, 310), l'appareil de couplage introduit des courant d'atténuation de résonance sous-synchrone dans la ligne de transmission (24, 204). Des détecteurs (44, 222, 237) surveillent les paramètres des lignes d'alimentation et/ou la vitesse du générateur, et, en réponse à ceux-ci, un contrôleur de haut niveau (86, 220) génère un signal de commande de tension (85, 308). Un contrôleur vernier (50) répond aux paramètres de ligne d'alimentation surveillés et au signal de commande de tension (85, 308) pour fournir un signal de commande de déclenchement (48, 310) à l'appareil de couplage.
