摘要
针对光伏发电系统教学研究实验平台普遍缺乏电能质量监测系统这一问题,提出了基于LabVIEW的光伏发电实验平台电能质量监测系统设计方案。该方案通过NI cDAQ-9174数据采集卡对实验平台中经过逆变的交流电进行采集,利用基于LabVIEW的电能质量分析监测模块对采集到的电能数据进行处理及判断,可有效避免由于实验平台逆变模块发生故障,而实验人员在未知的情况下接入负载单元导致其发生损坏的情况。运行测试表明,系统可靠性高、运行稳定,各项功能均达到了设计要求,有效提高了实验平台中负载单元的使用寿命。
In view of the problem that the experimental platform for teaching and research of photovoltaic power generation system generally lacks power quality monitoring system, a design scheme of power quality monitoring system for photovoltaic power generation experimental platform based on LabVIEW is proposed. This scheme collects the inverted alternating current in the experimental platform by NI cDAQ-9174 data acquisition card, and processes and judges the collected electric energy data by using the power quality analysis and monitoring module based on LabVIEW, which can effectively avoid the failure of the inverting module of the experimental platform and the damage caused by the experimenter accessing the load unit under unknown circumstances. The operation test shows that the system has high reliability and stable operation, all its functions have met the design requirements and the service life of the load unit in the experimental platform has been effectively improved.
