With the increasing scale of photovoltaic power plants owned by enterprises, the traditional power plant management methods are no longer applicable. The power plant operation and maintenance system tailored for power plant operation and maintenance came into being. It not only reduces the workload of operation and maintenance personnel , and the system is also very powerful, able to complete:
Data collection and analysis (meteorological data, power generation statistics, PR analysis, equipment operation)
String fault location, alarm center, defect management, automated report management and other functions.
Among them, data collection and analysis is the core of the operation and maintenance system. The data collected and analyzed include:
Combiner box data (string current, voltage)
Inverter data (real-time voltage, power generation, real-time power, etc.)
Real-time data of key points such as box-type substation, high-voltage side, grid-connected point, etc.
The operation and maintenance system is based on real-time data, which makes the operation and maintenance of the power station more efficient and is a very effective technical means.
However, it must be emphasized that even with the operation and maintenance system, the daily inspection work still needs to continue!
Some problems are blind spots for the operation and maintenance system, which are difficult to find. For example, there is no effective real-time monitoring method for the temperature of the equipment terminal. Infrared scanning is performed on the equipment terminals of the photovoltaic area and the booster station to find abnormal temperature points and eliminate hidden dangers in the bud.
