Photovoltaic power generator set performance monitoring method based on eight states

The invention discloses a photovoltaic power generator set performance monitoring method based on eight states. A hardware structure comprises an onsite side which is connected with a centralized control center side; the onsite side comprises a telecontrol machine which is connected with a communication manager, and the communication manager is connected with a first three-layer switch which is connected with a vertical encryption device; the centralized control center side comprises a vertical decryption device which is connected with a second three-layer switch, and one end of the second three-layer switch is connected with a real-time database and control server cluster and the other end is connected with a system monitoring terminal; and the vertical encryption device is connected with the vertical decryption device. The photovoltaic power generator set performance monitoring method based on the eight states has characteristics that fine management and monitoring can be performed on the inverters in a photovoltaic power generator set so that working efficiency is enhanced, availability rate of the photovoltaic power generator set is enhanced and labor intensity is reduced.
