AI Technical Summary

Problems solved by technology

[0004] The existing operation and maintenance system mainly uses the configuration monitoring system provided by the traditional power enterprise to protect the power equipment. The field mainly collects the data of the power equipment to realize on-site monitoring and maintenance. The main disadvantage is the large amount of data and the definition of fault alarm. It shows that there is no uniform specification, and it is not dedicated to photovoltaics. The monitoring system is improved from the traditional thermal power or hydropower system, and each manufacturer has its own communication system. The compatibility is average, and the data cannot be uploaded to the remote end. Cross-comparison analysis of multiple sets of data to realize remote monitoring and maintenance

In addition, there are some companies with a background in the communication industry and some operation and maintenance monitoring systems developed by companies in the photovoltaic industry, which mainly focus on the collection and display of inverter data without in-depth analysis of the data. Low, poor data accuracy, unable to accurately locate faults, high false alarm rate
