Definitions

  • One of the interconnection standards is fault-ride through capability which requires that the power generation system must remain connected to the power grid when one or more grid faults are occurring with the power grid.
  • One of the problems may be how to quickly and accurately detect or identify an open-circuit fault condition, as a failure to timely detect the open- circuit fault may lead to wrong response of the controller so that one or more electrical devices within the power generation system or one or more loads coupled with the power generation system may be damaged by the over-voltage or over- current caused from the open-circuit fault.
  • FIG. 1 is an overall block diagram of a power conversion system in accordance with an exemplary embodiment of the present disclosure
  • FIG. 2 is a detailed structure of a transformer shown in FIG. 1 in accordance with an exemplary embodiment of the present disclosure
  • FIG. 6 is a block diagram showing another aspect of the detailed implementation of the open-circuit detection module shown in FIG. 1 in accordance with one exemplary embodiment of the present disclosure
  • FIG. 7 is a block diagram showing another aspect of the detailed implementation of the open-circuit fault module shown in FIG. 1 in accordance with another exemplary embodiment of the present disclosure
  • FIG. 8 is a graph illustrating various waveforms of the power conversion system prior to, during, and subsequent to an open-circuit fault in accordance with an exemplary embodiment of the present disclosure
  • FIG. 9 is a flowchart which outlines an implementation of an open- circuit fault detection method in accordance with an exemplary embodiment of the present disclosure.
  • FIG. 10 is a flowchart which outlines an implementation of an open- circuit fault detection method in accordance with another exemplary embodiment of the present disclosure.
  • the solar power converter system 14 shown in FIG. 1 is based on a two-stage structure which includes a PV side converter 142 and a line side converter 144.
  • the PV side converter 142 may include a DC-DC converter, such as a DC-DC boost converter, which steps up a DC voltage received from the solar power source 12 and outputs a higher DC voltage onto a DC bus 146.
  • a PV side filter 22 may be coupled between the solar power source 12 and the PV side converter 142.
  • the PV side filter 22 may include one or more capacitive and inductive elements for removing ripple components of the DC power output from the solar power source 12 and blocking ripple signals transmitted from the PV side converter 142 to the solar power source 12.
  • FIG. 2 illustrates a detailed configuration of the transformer 24 shown in FIG. 1 in accordance with an exemplary embodiment of the present disclosure.
  • the transformer 24 includes three primary side windings 188, 192, 194 located proximate to the grid 18 and three secondary side windings 187, 191, 193 located proximate to the line side converter 144.
  • Each of the primary side windings 188, 192, 194 may share a common core leg (not shown) with each of the secondary side windings 187, 191, 193 correspondingly.
  • a first primary side winding 188 and a first secondary side winding 187 may be commonly wrapped around a core leg of the transformer 24.

Abstract

La présente invention se rapporte à un système de conversion de puissance (10) qui comprend un système de convertisseur (14) destiné à convertir la puissance d'entrée provenant d'une source de puissance (12) et à fournir une puissance de sortie ; un transformateur (24) destiné à fournir une transformation de tension ou de courant de la puissance de sortie et une isolation entre le système de convertisseur (14) et une charge (18) ; et un dispositif de commande de convertisseur (16). Le dispositif de commande de convertisseur (16) comprend un module de détection de circuit ouvert (210) destiné à recevoir un premier signal électrique (148, 152) et un second signal électrique (148, 152) mesurés au niveau d'un côté du transformateur (24) ; à déterminer si une valeur de différence entre les premier et second signaux électriques mesurés est inférieure à une valeur de seuil prédéterminée ; et à envoyer un signal de commande (168, 172) pour amener le système de convertisseur (14) à réduire la grandeur de la puissance de sortie lors de la détermination que la valeur de différence est inférieure à la valeur de seuil prédéterminée. Les premier et second signaux électriques comprennent des signaux de courant ou de tension.
