چکیده
As the scale of power grid continues to expand, human-based inspection method struggles meet needs efficient operation and maintenance. Currently, existing UAV system in market generally has short endurance time, high flight requirements, low degree autonomous flight, accuracy intelligent identification, slow generation reports, other problems. In view these shortcomings, this paper designs an based on self-developed UAVs, including planning paths, sliding film control algorithms, mobile schemes fault diagnosis. first stage, basic data such as latitude, longitude, altitude, length cross-arms are obtained from cloud database grid, while lateral displacement vertical during drone calculated, path is generated independently according type. second order make UAV’s more stable, reference-model-based mode algorithm introduced improve performance. Meanwhile, uploads captured photos real time. third a program designed efficiency. The transfer equipment realized process inspection. Finally, detection accuracy, high-precision object detector YOLOX network model, improved model increased mAP0.5:0.95 metric by 2.22 percentage points compared original YOLOX_m for bird’s nest detection. After large number verifications, greatly improves efficiency inspection, shortens cycle, reduces investment cost manpower material resources, successfully fuses field high-voltage transmission lines

A New Algorithm for Optimum Voltage and Reactive Power Control for Minimizing Transmission Lines Losses
Reactive power dispatch for voltage profile modification has been of interest Abstract to powerr utilities. Usually local bus voltages can be altered by changing generator voltages, reactive shunts, ULTC transformers and SVCs. Determination of optimum values for control parameters, however, is not simple for modern power system networks. Heuristic and rather intelligent algorithms have to be so...
متن کاملInspection of High Voltage Power Lines – a New Approach
This paper presents the “Cable Crawler”, a mobile teleoperated robot to inspect high voltage power lines. Its mechanism allows riding on the topmost ground cable of high voltage power lines and crossing a set of mast tips as well as smaller obstacles autonomously and thus is not limited to just move from mast to mast. The robot consists of an aluminium chassis, six propulsion units and two spac...
