Wireless Sensor Network Based Real-Time Monitoring and Fault Detection for Photovoltaic Systems

摘要

This paper presents design and implementation of a monitoring and fault detection for photovoltaic renewable energy system. A real-time monitoring unit based on wireless sensor networks is designed to monitor required variables related to each module and unit in the PV system. An intelligent algorithm based onfuzzy logic has been developed to detect and locate faults. A mathematical model together with an experimental prototype is designed to evaluate the performance of the proposed PV system under normal and faulty conditions. The obtained results from both simulated and experimental systems confirm that the implemented monitoring and fault detection system perform the required tasks with acceptable accuracy and cost.Applying real-time remote monitoring is easier to specify faults and observe the overall performance of any solar PV system.
