Aiming at the high-voltage transmission line protection device integrated with travelling wave fault location function

the overall hardware architecture design scheme of the device and the overall software implementation scheme of travelling wave fault location module are proposed. Besides

the reliability of travelling wave fault location function is improved by using relay protection information

and the overall integration of travelling wave fault location function and protection function is realized on the basis of not affecting the performance of relay protection

which provides a technical guarantee for improving the fault location performance of high-voltage transmission line pro-tection device. The simulation results verify the feasibility of the integration technology. The line protection device integrated with travelling wave fault location can accurately locate the line fault point in real time

greatly reduce the workload of manual line patrol

shorten the fault repair time

and improve the reliability of power supply.
