(JA) 電源品質管理システムならびに空気調和装置
Abstract:
(EN) According to the present invention, when a power supply power factor changes in a lagging direction, control units (43,47,52,62)perform a first control for controlling the power supply power factor or a power supply harmonic under a harmonic current such that an input power factor of at least one of a plurality of connection devices (41, 42) changes in a leading direction compared to the power supply power factor. In addition, when the power supply power factor changes in the leading direction, the control units (43,47,52,62)perform a second control for controlling the power supply power factor or the power supply harmonic such that an input power factor of at least one of the plurality of connection devices (41, 42) changes in the lagging direction.
(FR) Selon la présente invention, lorsqu'un facteur de puissance d'alimentation électrique change dans une direction de recul, des unités de commande (43, 47, 52, 62) réalisent une première commande pour commander le facteur de puissance d'alimentation électrique ou des harmoniques d'alimentation électrique sous des harmoniques de ballast de telle sorte qu'un facteur d'énergie d'entrée d'au moins un dispositif parmi une pluralité de dispositifs de connexion (41, 42) change dans une direction avant par rapport au facteur de puissance d'alimentation électrique. De plus, lorsque le facteur de puissance d'alimentation électrique change dans la direction avant, les unités de commande (43, 47, 52, 62) réalisent une seconde commande pour commander le facteur de puissance d'alimentation électrique ou les harmoniques d'alimentation électrique de telle sorte qu'un facteur de puissance d'entrée d'au moins un des dispositifs de connexion (41, 42) change dans la direction de recul.
(JA) 制御部(43,47,52,62)は、電源力率が遅れた方向に変化した場合、複数の接続機器(41,42)のうち少なくとも1つの入力力率が、電源力率より進む方向に変化するように、電源力率または高調波電流における電源高調波を制御する第1制御、を行う。また、制御部(43,47,52,62)は、電源力率が進んだ方向に変化した場合、複数の接続機器(41,42)のうち少なくとも1つの入力力率が、電源力率より遅れる方向に変化するように、電源力率または電源高調波を制御する第2制御、を行う。
