1. high pressure user photovoltaic generation electric energy metered system, it is characterized in that described system comprises photovoltaic array, direct current collector-shoe gear, direct current energy meter, combining inverter, step-up transformer, AC voltage transformer, AC current transformer, AC energy meter, power information collecting device and control computing machine;

  • The direct current energy that described photovoltaic array sends is by direct current collector-shoe gear access direct current energy meter;

    The voltage and current signal of described direct current energy meter is sent into combining inverter, boosts and the access user high voltage bus user'"'"'s high voltage bus access user load through step-up transformer;

    User'"'"'s high voltage bus accesses the power supply high voltage bus after AC voltage transformer, AC current transformer, through the small voltage current signal incoming transport electric energy meter of AC voltage transformer, AC current transformer conversion, the electric flux of electrical network and forward user power utilization is oppositely sent in the AC energy meter metering;

    The direct current energy that direct current energy meter is measured carries out data acquisition with the alternating current energy of AC energy meter measurement by the power information collecting device, through the power information collecting device with communication to controlling computing machine or main website.
