Smart Photovoltaics: Enhancing Fault Detection and Positioning
Smart photovoltaics (PV) technology aims to improve fault detection and positioning in large-scale PV systems. By equipping PV modules with AMP devices, real-time monitoring of environmental conditions and system status is enabled. The proposed automated troubleshooting method enhances efficiency in identifying and locating faulty modules, decreasing risks of accidents and system downtime in industrial and commercial scenarios.

September 2023 September 2023 PV Module Positioning in Industrial and Commercial Scenarios September 2023 Doc.: IEEE 802.11-23/1521r0 Challenges Faced by Large-Scale Smart PV Deployment Faults of PV modules affect the power generation efficiency and life cycle of the system, and may also cause serious accidents such as fire and electric shock. Therefore, troubleshooting and positioning are critical issues for operation and maintenance. There are a great number of PV modules in a power plant thus the deployment area is huge, which makes it difficult to accurately locate the faulty PV modules.

September 2023 September 2023 PV Module Positioning in Industrial and Commercial Scenarios September 2023 Doc.: IEEE 802.11-23/1521r0 Conventional scheme Invertor detection: can only achieve array-level fault detection and faulty modules cannot be accurately located. Manual module-to-module detection: time-consuming and labor-intensive Desired scheme: fully automated PV module-level troubleshooting and positioning Submission Slide 4 Shuqiao Chen (Huawei)
September 2023 September 2023 AMP Use Case: Smart Photovoltaics(1/2) September 2023 Doc.: IEEE 802.11-23/1521r0 Expected Service and Functionalities Each PV module can be equipped with an AMP device to monitor the operating environment and status. Fault pretreatment: AMP device periodically reports sensing data (e.g. temperature, current, voltage, etc.) to the data collector which is then forwarded to the server for fault pretreatment. Fault positioning: When the invertor detects an array-level fault, it informs the server/data collector, which will trigger all the AMP devices in the faulty PV array to transmit their sensing data, from which faulty PV module can be determined. After that, the server/data collector will perform a positioning procedure to position the faulty PV module. Data Collector Server AMP Device ......
