光伏电站直流侧多种测试方法的研究

Research on Multiple Testing Methods on the DC Side of PV Stations

文章从质量监督的角度出发,以提高检测效率、检测过程不中断发电设备正常工作和快速诊断故障原因为目标,利用自主开发的2款光伏电站现场测试设备,以其配套的现场测试方法来检测光伏电站直流侧电流值、电压值。研究了这两种检测方法的应用场景,通过合理使用这2种检测方法,可更好地反映光伏电站直流侧组串级的运行质量,对于提高光伏电站工作状况质量监督的效果有一定应用价值。

Starting from the perspective of quality supervision,with the objectives of improving the testing efficiency,not interrupting the normal work of power generation equipment during the testing process,and quickly diagnosing the causes of faults,this paper utilizes 2 self-developed PV field testing equipment for PV power stations,and monitors the DC-side current value and voltage value of PV stations with its supporting field testing methods.The application scenarios of these two testing methods are studied,and through the rational use of these two testing methods,the operation quality of the DC side string level of PV power stations can be better reflected,which is of certain application value for improving the effect of quality supervision of the working condition of PV stations.
