便携式光伏电站多路电流比测仪的研发与应用

Research and Application of Portable Multi-channel Current Ratio Tester for PV Station

文章描述了一种便携式光伏电站多路电流比测仪的研发。该检测仪专门针对光伏电站现场环境,同一时间内能检测到光伏电站多个组串的电流瞬时值,并能进行比对,找出其中过低的电流瞬时值,发现电流值小的组串,从而快速、准确找出光伏电站中具有“短板”效应的发电单元。并介绍了该设备在大型光伏电站实际运用的情况以及检测的效果。

This paper describes the development of portable multi-channel current ratio tester for PV station.This tester is specifically used for PV station on-site environment.It can detect and compare the current instantaneous value of multiple strings of the PC box at the same time,then find out the lowest current instantaneous value.After that lowest current strings so called“short board”effects can be found quickly and accurately.And the actual application and effect of detection of this tester in large-scale PV station is introduced.
