Abstract
(EN)
The present invention relates to a method for tracking a maximum power point of a photovoltaic power conversion apparatus, in which the maximum power point is tracked by sensing the voltage, current, and temperature of solar cells and, more specifically, to a method for tracking a maximum power point of a photovoltaic power conversion apparatus, in which, by tracking the maximum power point using the temperature of a solar cell module, accurate maximum power point tracking is possible, and thus damage from a fire caused by the occurrence of hot spots in a solar cell module can be prevented, resulting in the extended lifespan of the solar cell module, and in which a power conversion unit can prevent loss that may occur as a result of tracking power, not maximum power, and accordingly, can transmit a signal to an upper-level control circuit, thereby securing safety.

La présente invention concerne un procédé de suivi d'un point de puissance maximum d'un appareil de conversion d'énergie photovoltaïque, dans lequel le point de puissance maximum est suivi par détection de la tension, du courant et de la température de cellules solaires et, plus précisément, un procédé de suivi d'un point de puissance maximum d'un appareil de conversion d'énergie photovoltaïque, dans lequel, par suivi du point de puissance maximum à l'aide de la température d'un module de cellule solaire, un suivi précis de point de puissance maximum est possible et, par conséquent, un endommagement d'un feu provoqué par l'apparition de points chauds dans un module de cellule solaire peut être empêché, conduisant à l'extension de la durée de vie du module de cellule solaire et dans lequel une unité de conversion de puissance peut empêcher une perte qui peut se produire à la suite d'un suivi de puissance, non une puissance maximum, et par conséquent, peut transmettre un signal à un circuit de commande de niveau supérieur, ce qui permet d'assurer la sécurité.

본 발명은 태양전지의 전압, 전류 및 온도를 감지하여 최대전력을 추종하는 것을 특징으로 하는, 태양광 전력변환장치의 최대전력 추종방법에 관한 것으로, 더욱 자세하게는 태양전지 모듈의 온도를 이용하여 최대전력지점을 추종함으로서 정확한 최대전력 추종이 가능함에 따라, 태양전지 모듈의 열점현상에 의한 소손을 방지하여 태양전지 모듈의 수명을 연장할 수 있으며, 전력변환부가 최대전력이 아닌 전력을 가져옴으로서 발생할 수 있는 손실을 방지할 수 있고, 이에 따라 상위 제어회로에 신호를 보내어 안전을 담보할 수 있는 태양광 전력변환장치의 최대전력 추종방법에 관한 것이다.
