电力线路电气参数测量研究综述OA

The electrical parameters of power lines are critical foundational data in fields such as power system analysis,relay protection and fault location.Their measurement accuracy directly affects the safety and reliability of power system operations,and holds significant research and application value.This paper systematically reviews the calculation models of electrical parameters in power lines,the differences in their measurement methods,and the suppression strategies for induced voltages during the measure process,then elaborates in detail on the core connotations of the centralized parameter,distributed parameter and phase parameter models,and comparatively analyzes the technical advantages and application limitations of the power frequency method and the hetero-frequency method.The paper also makes analyses on the working principles of two induced current suppression methods,and finally combines with the current technological status to discuss the challenges faced in the field of electrical parameter measurement for power lines,and looks forward to the future development trends.
