AI Technical Summary
Existing grid-connected photovoltaic cabinets may experience problems such as voltage and frequency fluctuations on the grid side during operation, leading to equipment damage and safety threats. At the same time, serious harmonic problems and the uncertainty of photovoltaic power generation cause random fluctuations in output power, affecting grid stability.
An adaptive intelligent grid-connected cabinet was designed, which integrates anti-islanding protection devices and online power quality monitoring devices. Combining artificial intelligence, Internet of Things and big data technologies, it can realize real-time monitoring and rapid response of grid signals and has intelligent monitoring and diagnostic functions.
By quickly eliminating islanding phenomena and monitoring power quality in real time, reliable grid operation can be ensured, equipment damage and safety risks can be reduced, and the stability and reliability of the power system can be achieved.
