Grid

The Grid structure contains variables to output information on the electrical supply system. The measured outer conductor voltage, as well as additional information about the grid status and fed-in or recovered active energy.

Variable name

Description

rActualGridInputEnergy

Data type: REAL

Total energy fed into the DC link [kWh] (since the counter was last reset)

rActualGridOutputEnergy

Data type: REAL

Total energy recovered to the grid [kWh] (since the counter was last reset)

rActualGridVoltage

Data type: REAL

Actual rms value of line voltage [V]

rActualGridActivePower

Data type: REAL

Actual active power [W]

  • Positive: The device feeds into the DC link
  • Negative: The device feeds into the grid

xMainsConnected

Data type: BOOL

  • TRUE: The line contactor is closed and the voltage is within the permitted range (the grid is connected).
  • FALSE: The measured voltage is not within the permitted range. Either the line contactor is not closed or the line voltage is not within the permitted range.
