1 Introduction
The WTC3 Grid module is used to measure 3 phase voltage, current, active and reactive power.
The measured values can be continually read out by a CAN communication interface. The CAN
interface are also used to program the module with parameters that adjust how the measurement
is done. The module also contains thyristor control outputs that can be used for soft cut-in of wind
turbines that does not use a power converter. Also the module contains grid monitoring
functionality that can monitor the grid measurements and control a relay output depending on
parameter threshold level.

4.3 Supervision
The power supply is supervised to protect the module from malfunctions due to AC power line
drops and errors in the internal power supplies.
If a power fail is detected the module disables all outputs and disconnects from the CAN bus.
The module must be powered down to exit this safety state.
4.4 Measure +24Vsensor current
Current consumption on +24Vsensor supply can be measured on the module via test terminals
between X7/X8. The signal is 1mV per 10mA.

10 Soft generator cut-in
The module contains a current controller that is intended for soft generator cut-in, by using
thyristors. If desired, the thyristor angles can also be directly controlled via CAN. A block diagram
of the current controller is shown below.
The PI-Controller has four parameters: “Cut-in Current Control Gain Positive”, “Cut-in Current
Control Gain Negative”, “Cut-in Current Control Integration Time” and “Cut-in Start Angle”. The
first three are standard PI-Controller parameters. The “Cut-in Start Angle” parameter is used to
initialize the integration.
The current ramp set point is a ramp, which can be adjusted by setting the corresponding
parameters. The parameters are:
• Cut-in Current Reference
• Cut-in Current Ramp Time
• Cut-in Current Control Start Current
The minimum thyristor angle ramp is a ramp that ensures that the thyristor angles will reach the
angle given by “Cut-in End Angle” within the time set by “Cut-in Max Time”.
The current ramp set point and the minimum angle ramp are shown below:
