Abstract

Abstract: This paper analyzed the current situation of the research on DC arc fault detection in PV system.With common time-frequency domain detecting method,it did the DC arc fault detection and test in different PV system and the operating conditions.Based on the test results,the paper summarized the time-frequncy domain characteristic of DC arc fault,and the influence of different system and condition on DC arc fault detection.Finally,a DC arc fault detecting device of PV system was developed,which can used in DC arc fault detection inter different PV system and working condition.The effectiveness of the device was verified.

Key words: photoweltaic system, DC arc fault, support vector machine, adaptive harmonic cancellation
