Differential GPS-Based Transmission Conductor Wave and Wind Galloping Real-Time Measurement

Based on differential GPS (DGPS) technology, a realtime direct measurement method of transmission conductor wave and wind galloping is proposed. The hardware structure of the DGPS-based real-time measurement system is described. The design method, DGPS data acquisition and processing are introduced. Artificial neural network (ANN) is used to improve the accuracy of the DGPS measurement system. Virtual reality modeling language (VRML) drawing program is used to draw the tracks of the conductor wave and wind galloping. The experimental results prove that the DGPS-based transmission conductor wave and wind galloping real-time measurement is feasible.
