So, in such cases, the faulted elements must be found immediately. If we want to find the faulted elements at the dispatching center, we must infer them from the state of protective relays and circuit brakers, after the faulted elements have been removed from the energized power system. (we can not obtain the information of the sequence of these apparatus’ action owing to the communication system.) Although some reports have been published by which we can infer the faulted elements from the state of the protective relays, a redesigning of existing protective relays must be necessary for practical application of these logics. So, the author proposes the discriminative logic of faulted elements by which we can infer a faulted elements from the state of existing protective relays. In this paper, at first, the author proposes a discriminative logic of faulted elements by which we can infer the faulted elements from the digital information that is made from the state of existing protective relays and circuit brakers after the fault. Next, the author confirms that the proposed logic is very effective for practical application, by simulating the logic using the data of real complex faults which have happened in some electric utility.}, pages = {51--63}, title = {自動復旧操作のための事故区間推定論理*}, volume = {11}, year = {1979} }
