摘要
文章通过对国内多个充电站的电能质量进行采集和分析,发现存在电压有效值超限、电压骤变、谐波畸变率超限、电压跌落等问题。针对实际工况所得到的工况,在试验室搭建电网适应性测试台架,提出OBC的交流电网适应性测试方法,包括供电电压超限测试、供电电压骤变测试、电网谐波失真测试以及电压跌落测试等,全面评估OBC在不同电能质量问题下的适应能力。通过这些测试方法,能够系统检测和提高车载充电机的性能和可靠性,为电动汽车充电系统提供可靠的技术支持,确保其在各种电网条件下的正常运行,促进OBC安全性能健康发展。
This study collects and analyzes power quality data from multiple charging stations across the country,identifying issues such as voltage over-limit,voltage fluctuations,harmonic distortion,and voltage sags.Based on the actual operating conditions obtained,a grid adaptability testing platform was established in the laboratory.The OBC AC grid adaptability testing methods proposed include voltage over-limit testing,voltage fluctuation testing,grid harmonic distortion testing,and voltage sag testing,comprehensively evaluating the OBC's adaptability to different power quality issues.These testing methods systematically detect and improve the performance and reliability of OBCs,providing reliable technical support for electric vehicle charging systems,ensuring their normal operation under various grid conditions,and promoting the healthy development of OBC safety performance.
