| Abstract: |
| In order to carry out the type test of fault location equipment, the relevant standards of transmission line travelling wave fault location equipment are analyzed. In view of the influence factors of range accuracy, functional and performance testing system and test items are proposed. Through detailed introduction of test case, the methods of simulation model establishing and fault setting are introduced in detail. Experimental results demonstrate the validity and practicability of the method of testing. At last, according to the standard DL/T 357-2010 and on the basis of examination of fault recorders throughout the years, an evaluation mechanism of fault location equipment is proposed, which can evaluate software and hardware comprehensive performance of device, and can put forward the device applications scopes that provide technical support and guarantee for device selection. |
