BRIEF ANALYSIS ON HAZARD CONTROL OF HOT SPOT PV MODULES
As the operating time of PV power stations increases,the hazard caused by hot spot faults in PV modules is an urgent problem that needs to be solved.This paper explores the causes and hazards of hot spot PV modules in PV power stations,analyzes the advantages and disadvantages of existing detection methods for hot spot PV modules,and proposes hazard control methods for hot spot PV modules from three aspects:internal,external,and the entire life cycle of PV power stations.For hot spot faults caused by internal quality issues,it is proposed to classify them according to the temperature difference between different positions of hot spot PV modules,and evaluate the impact of hot spot PV modules on the power generation of PV power stations and the safety hazards that exist in PV power stations.Based on the market price of PV modules,the cost recovery period of PV power stations,and the severity of hot spot PV modules,a cost-effectiveness analysis is conducted on whether to replace hot spot PV modules,and the analysis results are used to determine whether to replace PV modules.In order to provide theoretical support and practical guidance for the safe and stable operation of PV power stations using this method.
