The ground power station is entering the era of ultra-high power string. The span of single machine power makes the system successfully realize
” True string “design. The so-called “true string” is not a simple string architecture, but on high-power platforms, still fine enough

road, the ability of each path

lies not only in” whether it can be found “, but also in” whether it can be found in time and accurately “. Through self-research
The multi-peak scanning optimization algorithm can quickly scan the global curve and accurately identify the true global maximum power point. Even in complex occlusion scenes, the system can re-lock the optimal working point in about seconds, while the traditional scheme often requires

as the system scale continues to expand, the DC side voltage is higher and the number of strings is more. Any local abnormality may be rapidly amplified. Therefore, the security capability is no longer just
way string, once the background alarm, the scope of the problem can quickly converge. Compared with the traditional scheme, the fault location efficiency can be improved by about times, the troubleshooting and downtime can be greatly shortened, and the operation and maintenance can move from “large-scale search” to “precise location”.

what the ground inverter wants to answer is actually the same question: as the scale of the power station becomes larger and larger, can the string inverter continue to maintain its core value?
The answer is yes. The high-power platform does not necessarily mean extensive management. The truly advanced high-power string inverter should make the power generation control more detailed, the fault location more accurate and the safety boundary more firmly while making the system larger.
