Department of Power Scientific Research of Hunan Province Power Company of State Grid, Changsha 410007, China; 2. State Key Laboratory of Advanced Electromagnetic Engineering and Technology, Huazhong University of Science and Technology, Wuhan 430074, China） Optical fiber differential protection is widely used as the primary protection of power transmission line, but it may be influenced by extreme natural and man-made hazard which would impair protection performance. This paper discusses a technical scheme of pilot differential protection channel based on wireless sensor network. Taking the number of nodes and failure rates into account, redundancy arrangement of nodes based on reliability of the whole communication network and optimal cost is proposed. Besides, this paper studies the influence of the communication distance, lin |
