The On-Line Monitoring Method for Drainage Wire Galloping in High Voltage Overhead Power Transmission Line

Abstract:

In order to analysis wave characteristic of drainage wire, considering the shortcoming of existed measuring systems, including lack of accuracy and heavy load of data transmission, and combining with the PDR system which has been widely used in absolute position of a pedestrian, the on-line monitoring method for drainage wire galloping is proposed, which is based on accelerometer and gyroscope. Min-vector of angular velocity is applied to capture the onset/end of each gallop. ZUPT algorithm is implemented to correct the galloping velocity at onset when errors existed. Cluster sampling and quadratic integral are used to measure Galloping parameters accurately. The galloping orbit is also displayed dynamically. Finally, practical experiments are carried out. The feasibility and availability of the on-line monitoring method based on PDR system are demonstrated. The method can measure wave amplitude, wave speed and wave trajectory precisely, and offer technical support for in-depth research of drainage wire galloping.
