In accordance with the new requirements of modern power distribution grid on feeder automation, the limitations of feeder terminal unit (FTU) with TMS320LF2407 as the main control chip are analyzed, and the improved design scheme of the FTU is proposed. With TMS320F28335 as the core processor, the overall performance is upgraded, and the function of GPRS wireless network communication is added to realize the coexistence of multiple types of communication. The improved fault positioning algorithm is adopted to implement rapid fault positioning;the concrete implementing mode for fault recording is given to provide reliable basis of fault analysis. The test results of example show that precise fault positioning can be realized when fault occurs, this makes power supply to be recovered promptly, thus satisfies demands for automation of modern power grid.
