Title: (KO) 인버터 시스템에서 전력 케이블의 상태 검출 방법
(EN) METHOD FOR DETECTING POWER CABLE STATE IN INVERTER SYSTEM
Abstract:
(KO) 실시 예에 따른 인버터 시스템에서 전력 케이블의 상태 검출 방법은, 인버터 내에 포함된 직류단 커패시터에 대한 직류단 전압 값을 검출하는 단계; 상기 인버터로 직류 전력을 공급하는 배터리의 전압 값을 검출하는 단계; 상기 직류단 전압 값과 상기 배터리 전압 값을 비교하는 단계; 및 상기 직류단 전압 값과 상기 배터리 전압 값의 차이 값이 기설정된 범위를 벗어나면, 상기 인버터와 배터리 사이를 연결하는 전력 케이블의 상태가 이상 상태인 것으로 판단하는 단계를 포함한다.
(EN) A method for detecting the state of a power cable in an inverter system according to an embodiment of the present invention comprises the steps of detecting a voltage value of a DC stage for a DC stage capacitor which is included in an inverter; detecting a voltage value of a battery for supplying DC power to the inverter; comparing the voltage value of the DC stage and the voltage value of the battery; and determining that the state of the power cable connecting between the inverter and the battery is in an abnormal state if a difference value between the the voltage value of the DC stage and the voltage value of the battery goes beyond a preset range.
