Query: Adaptive Zone-2 Distance Protection Scheme for Multi-Terminal Line
  Connecting Wind Farm   Wind energy is one of the fastest growing renewable sources in the world that
converts wind power into the electricity through wind farms. Stochastic nature
of the wind power makes interconnection of wind farms to the grid unreliable.
Thus, in order to enhance the system stability, it is important to protect
different parts of the power system specifically transmission lines. Since
distance relays are the primary devices in the protection of lines, adjusting
their setting is a crucial issue in terms of mitigating the rate of disruption
and increasing the overall stability. In this paper, the impact of wind speed
variation in the second zone of the distance relay has been studied. To monitor
distance relay operation part of a power system is simulated in PSCAD/EMTDC.
Then, an adaptive Technique is proposed to coordinate zone-2 operation in
accordance to other zones and prevent over/under reach. This method is based on
the Neural Network in MATLAB Simulink to adjust the second zone automatically
due to occurring instantaneous changes in the grid.
