Development of a Distribution Network Fault Location Device Based on Wide Area Measurement Information

Aiming at problems with current distribution network fault location devices, this paper presents a distribution network fault location device based on wide area measurement information. It elaborates the hardware design of the device such as functions and interfaces of modules, as well as its software process design. Finally, the acquisition accuracy test and phase to phase communication test prove its high reliability of data acquisition and feasibility of communication. This device supports current phasor acquisition, fault wave recorder and remote communication, has functions which traditional fault indicators cannot perform due to the power limit, and has a good application prospect in the future.
