The dynamic load management system of transmission line is used to solve the problems such as limited load capacity of transmission line and difficult to meet the demand of load growth, and to improve the operation level and load capacity of the line without changing the existing network structure and without affecting the thermal stability of the line.

Due to the technical limitations of the traditional transmission line fault location device, it is difficult to quickly and accurately locate the fault point and identify the fault type when the fault of the transmission line occurs in the complex operating environment (lightning strike, mountain fire, wind deviation, tree barrier, floating object, etc.). The distributed fault diagnosis device for transmission lines is based on fault local recording technology and traveling wave location method, which can effectively solve the problems of low positioning accuracy and difficult identification of fault types of traditional fault location devices.
