Simulation of partial discharge location in medium-voltage power cables

The medium voltage power cable with defects may generate partial discharge. An accurate location method of partial discharge source will protect system by repairing it as soon as possible. The conventional location methods, Time Delay Reflection (TDR) and Double-sided measurement, have different disadvantages. This paper proposes an accurate location method of partial discharge source, and improves the disadvantage of traditional location methods that the algorithm is related to time. Recognition and Synchronization are the problems. Our paper developed a location method having nothing to do with time, and used MATLAB to simulate the signal traveling along the cable under different environment to prove that the method is work.
