Title
(EN) WIND TURBINE GENERATOR WITH OVERSPEED DAMAGE PREVENTION
(FR) GÉNÉRATEUR ÉOLIEN À PRÉVENTION DES DOMMAGES DE SURVITESSE
(KO) 과속 피해 방지 풍력 발전기
Abstract
(EN)
The purpose of the present invention is to provide a wind turbine generator with overspeed damage prevention, which prevents electrical damage to a wind power controller by measuring the gradient of voltage transmitted from a wind power generation unit to predict overvoltage and consuming energy through a resistor according to the gradient value.
(FR)
L'objectif de la présente invention est de fournir un générateur éolien à prévention des dommages de survitesse, qui empêche un endommagement électrique d'un dispositif de commande éolien en mesurant le gradient de tension transmis à partir d'une unité de production d'énergie éolienne pour prédire une surtension et en consommant l'énergie à travers une résistance en fonction de la valeur de gradient.

본 발명은 풍력 발전부에서 전달되는 전압의 기울기를 측정하여 과전압을 예측하고, 기울기 값에 따라 저항을 통해 에너지를 소모하여 풍력 제어부의 전기적 손상을 미리 방지하는 과속 피해 방지 풍력 발전기를 제공하는데 그 목적이 있다.
