摘　　要：基于同步相量技术的广域测量系统的出现,电力系统动态数据的获取已变得方便快捷,从而为电力系统的参数辨识提供了条件。研究了输电线路参数辨识的问题,将WAMS数据和人工智能算法相结合应用在输电线路参数辨识中,阐述了辨识的具体方法和过程。仿真实验验证了该方案的正确性和有效性。As WAMS based on GPS be wildly used, the access for dynamic data of power system has become easier and faster, which provides convenient conditions for parameters identification of power system. This paper studies parameters identification of transmission lines. WAMS data and artificial intelligence algorithm is applied to parameters identification of transmission lines. The specific method and process of on-line identification method axe put forward. It is proved that the principles and measurement system explained in the paper are correct, effective and very useful for power industry. The paper is of some significance.
