Title (EN) ARC HANDLING CONTROL DEVICE AND ARC HANDLING CONTROL METHOD
(FR) DISPOSITIF ET PROCÉDÉ DE COMMANDE DE GESTION D'ARC
(JA) アーク対応制御装置およびアーク対応制御方法
Abstract:
(EN) The objective of the present invention is to reduce erroneous detection of arcs, and to reduce erroneous responses concomitant with erroneous detection. In a photovoltaic power generation system (100), a main control unit (37) controls an arc detecting device (40) in such a way as to suspend arc detection during periods in which arc-like noise is being generated. Examples that can be cited of periods during which arc-like noise is generated include a period from when a PCS (30) starts up to when the supply of power to a power grid (80) begins, and a period during which a current (I) flowing from a power generating device (10) to the PCS (30) is changing suddenly.
(FR) L'objet de la présente invention est de réduire une détection erronée d'arcs, et de réduire des réponses erronées concomitantes à une détection erronée. Dans un système de production d'énergie photovoltaïque (100), une unité de commande principale (37) commande un dispositif de détection d'arc (40) de manière à suspendre la détection d'arc pendant des périodes durant lesquelles est généré du bruit de type arc. Des exemples qui peuvent être cités de périodes durant lesquelles est généré du bruit de type arc comprennent une période allant du moment où démarre un PCS (30) au moment où commence l'alimentation en puissance d'un réseau électrique (80), et une période durant laquelle un courant (I) circulant d'un dispositif générateur de puissance (10) au PCS (30) varie brusquement.
(JA) アークの誤検出および誤検出に伴う誤対応を低減する。太陽光発電システム(100)において、主制御部(37)は、アーク類似ノイズが発生する期間、アークの検出を停止するようにアーク検出装置(40)を制御する。アーク類似ノイズが発生する期間の例としては、PCS(30)が起動してから電力系統(80)への電力供給を開始するまでの期間、および、発電装置(10)からPCS(30)に流れる電流(I)が急激に変化する期間が挙げられる。
