5.2.2 Internally logged data
The AURORA inverters store the following data internally:
¾ Lifetime counter of grid connection time
¾ Lifetime counter of energy transferred to the grid
¾ Energy transferred to the grid every 10 seconds for the last 8,640 of 10-second
periods (that covers more than 2 days of logged data)
¾ Partial counter of grid connection time (counter start time can be reset using the
AURORA Communicator software)
¾ Partial counter of energy (uses the same start time as the partial time counter)
¾ Last 100 fault conditions with error codes and time stamp
¾ Last 100 changes to grid connection parameters with parameter code and new
value.
All data can be retrieved via the RS-485 interface. In addition, the first two types of
data are displayed on the LCD screen.
5.3 LED indicators
There are three LEDs on the side of the LCD display as shown in Fig. 18: the first
LED from the left (POWER) indicates proper operation of the inverter, the LED in the
middle (FAULT) indicates a fault condition, and the LED on the right (GFI) indicates
a ground fault.
1. The green “Power” LED indicates that AURORA is operating correctly.
This LED flashes upon start-up during the grid monitoring routine. If a correct grid
voltage is detected and the input voltage is high enough to start up the inverter, the
LED stays on constantly. Otherwise, the LED keeps flashing until the wind turbine
speed and therefore the input voltage becomes high enough to start up the inverter.
In this condition, the display will read “ Waiting for Wind….”
2. The yellow “FAULT” LED indicates that AURORA has detected a fault condition.
A fault description appears on the display.
3. The red “GFI” (ground fault) LED indicates that inverter has detected a ground
fault in the wind turbine/rectifier system (DC side). When this kind of fault is
detected, the AURORA inverter immediately disconnects from the grid and the
corresponding fault message appears on the display. The inverter remains in this
condition until the operator presses the ESC button to re-start the grid connection
sequence. If the inverter does not reconnect to the grid after pressing the ESC
button, then call service to troubleshoot the system.
