9.11.3 Functionality
The Petersen coil controller function PASANCR is a numerical automatic controller
for the stepless adjustment of the arc suppression coil (ASC or Petersen coil) and
the control of the parallel resistor of the coil. It can be applied to compensated
networks for arc suppression coils with or without parallel resistor to increase the
resistive earth-fault current. The controller can also manage an additional parallel
fixed coil control.
PASANCR is intended for controlling arc suppression coils in networks with natural
ground capacitance asymmetry, for example, mixed overhead line and cable
networks. The main features of the function are:
• Operation based on forced change in zero-sequence voltage
• Arc suppression coil tuning to the desired position
• Network parameter calculation and displaying of the resonance curve and the
fault current estimate curve of the network
• Control of the parallel resistor
• Clear numerical value of the resonance point steady-state zero-sequence voltage,
for example, for earth-fault protection purposes
