Abstract | An electric power conversion device according to an embodiment of the present invention comprises: a phase synchronization circuit that calculates the phase of the system voltage of one or a plurality of electric power systems that are connection destinations; and a control unit that changes the gain of the phase synchronization circuit on the basis of the connection state of one or a plurality of power generation devices constituting an electric power system. This enables the convergence of the control state and the provision of a stable power supply even in cases when the variations in the short-circuit capacity of a system are large.
Un dispositif de conversion d'énergie électrique selon un mode de réalisation de la présente invention comprend : un circuit de synchronisation de phase qui calcule la phase de la tension de système d'un ou d'une pluralité de systèmes d'alimentation électrique qui sont des destinations de connexion ; et une unité de commande qui modifie le gain du circuit de synchronisation de phase sur la base de l'état de connexion d'un ou d'une pluralité de dispositifs de génération d'énergie constituant un système d'alimentation électrique. Ceci permet la convergence de l'état de commande et la fourniture d'une alimentation électrique stable même dans les cas où les variations de la capacité de court-circuit d'un système sont importantes.
実施形態の電力変換装置は、接続先である一また複数の電力系統による系統電圧の位相を算出する位相同期回路と、電力系統を構成している一または複数の発電装置の接続状態に基づいて位相同期回路のゲインを変更する制御部と、を備えるので、系統の短絡容量の変動が大きい場合であっても、制御状態を収束でき、安定した電力供給が行える。 |
