Embodiment Construction
[0036] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0037] see Figure 1a, a photovoltaic system arc fault detection method under abnormal lighting conditions: After confirming that no arc fault event occurs in the photovoltaic system, the MPPT algorithm action detection is performed, and the set threshold in the DC fault arc detection device is dynamically activated after the action Track changes in work points. By making the threshold value of judging arc fault features closely track the change curve of the system operating point adjusted by the MPPT algorithm, it is possible to deal with situations such as dynamic changes or continuous low power of fault arc detection caused by changes in illumination, and to ensure that the detection device can effectively detect the photovoltaic system at any time. The fault arc detection is completed under abnormal lighting conditions, and the interference of the...
