A method for power systems alarm handling and fault location is presented. The method employs artificial neural network classifiers whose inputs are alarms from relays and circuit breakers operation, while the outputs identify the faulted system component. Fault location is determined even in cases of protection system failures or in the presence of noisy data. The employed methodology is illus...

This paper proposes an approach to software faults diagnosis in complex fault tolerant systems, encompassing the phases of error detection, fault location, and system recovery. Errors are detected in the first phase, exploiting the operating system support. Faults are identified during the location phase, through a machine learning based approach. Then, the best recovery action is triggered onc...

Object-oriented programming has received wide acceptance in power system applications. The main advantages achieved by using the object-oriented techniques include easy maintenance, enhanced expandability and inherent implementation flexibility. This paper presents recent software developments of a fault location system implemented using object-oriented approaches and C++ programming language. ...

Fault location remains a challenging problem in order to restore power supply rapidly. In this paper, a novel single-terminal traveling wave fault location procedure is proposed in a radial distribution network. Firstly, the propagating speed of zero mode traveling wave is determined by BP neutral network method. Then the preliminary estimation of fault distance is calculated based on the diffe...
