The protective relaying system not only be able to provide the defense function against power system collapse, but also provides a fault detection, fault classification, and fault location algorithms with high reliability for long term usage. The research has an orientation towards practical considerations, and the developed algorithm is adaptive to changes of transmission lines or multi-faults situations. This feature can reduce a lot of fixed costs for periodically purchasing new equipments. The research task includes the development of database and data mining system, high-robustness fault detection, fault classification, fault location algorithms, and implementation of the developed algorithms on an Altera FPGA. The three-year proposal is planning to carry out in the following three stages: 1. The first year: In this stage, the project is planned to develop the fault detection and classification algorithms that can be utilized to protect the transposed/untransposed single- and double-circuit transmission lines. A dynamic structured neural network algorithm is planned to be developed and utilized to classify fault types on transmission lines. Because the developed protective relaying algorithm is adaptive to changes of transmission lines or multi-faults situations, the developed protective relaying system is suitable for long term usage. In this stage, a database and data mining system are planned to be established for systematically organizing measured fault data. Using the developed data mining system, the fault detection and classification algorithms can be trained more precisely and objectively. The performance of the proposed protective relaying algorithms will be evaluated by the fault data generated by EMTP. Using these fault detection and classification algorithms, the relay can achieve the single-pole reclosure function to promote the reliability, quality, and stability of the power system.保護電驛故障偵測故障定位故障判別類神經網路晶片設計。Protective relayingfault detectionfault locationfault classificationneural networksFPGA prototype design.輸電線保護電驛系統之高強健性演算法設計
