- This is Part I of a two-part paper which presents a methodology for fault location and isolation and service restoration for power distribution grids. Concepts of node, region, connected sub-grid, and simplified model of distribution grids are introduced. A simplified load flow analysis is discussed based on node-and-region load transformations. Complicated circuit analysis is avoided. Five criteria are proposed for fault location, including the distinguishability of multiple single-region faults and multiple multi-region faults. The fault is first located in a monitoring region and then in an action region. After that the action nodes of the action region are tripped to isolate the fault. Two service restoration schemes among a total of four are introduced in Part I. Tabu search is applied to seek for a close-to-optimal service restoration solution. The proposed approaches can be used in a grid of any scale. They have been imbedded in 26 power distribution automation systems of 10kV grids since 2013, and have been proven to be a great success.
