This paper presents a fault detection system based on multilayer feedforward artificial neural network (ANN) for detection of one or several broken parallel coils of a small generator. This fault type cannot visibly influence on machinepsilas normal performance and since the performance of a faulty machine with broken coils is similar to that of a healthy one with unbalance load, therefore detection...
A current differential protection protects the winding of a generator. The relay must not operate on the occurrence of external fault. There is a power plant in Thailand where the generators were tripped by external fault. The tripping of generator results in severe stability problem. The case study shows single line to ground external fault on a transmission line. The fault current wave shapes were...
