Photovoltaic Power Station

With the continuous development of photovoltaic power station, intelligent power management becomes more and more important, and there are higher requirements for DC cabinet. In this paper, several schemes commonly used in DC power distribution cabinet power detection of photovoltaic power station are briefly introduced.

　　1. bus (current, voltage) detection

　　2. bus (current, voltage, power, electricity) detection and switching value acquisition

　　3. bus/branch (current, voltage, power, electric degree and switch value) detection

　　4. bus insulation and branch insulation monitoring

　　5. bus/branch (current, voltage, power, electrical degree and switching value) detection, bus insulation, branch insulation detection
