摘要：
风能是世界上增长最快的可再生能源之一，通过风电场将风能转化为电能。风能的随机性使风电场并网不可靠。因此，为提高系统稳定性，保护电力系统不同部分，特别是输电线路至关重要。由于距离继电器是线路保护的主要设备，调整其设置在减少中断率和提高整体稳定性方面至关重要。本文研究了距离继电器第二区中风速变化的影响。为了监测距离继电器的操作部分，对电力系统的部分进行了PSCAD/EMTDC仿真。然后提出了一种自适应技术，以根据其他区域协调Zone-2操作，防止过/欠reach。该方法基于MATLAB Simulink中的神经网络，以调整第二区，以应对电网中发生的瞬时变化。
英文摘要：
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.
