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 recovery of distribution network is realized by operating switches to change topological structure of the network. The final destination of fault recovery is power loss minimization, fault isolation and power load transfer. This article has built the mathematical model of fault recovery considering constraints of node voltage, line capacity and power flow balance. The objective function i...

The real-time fault diagnosis system is very great important for steam turbine generator set due to a serious fault results in a reduced amount of electricity supply in power plant. A novel real-time fault diagnosis system is proposed by using strata hierarchical fuzzy CMAC neural network. A framework of the fault diagnosis system is described. Hierarchical fault diagnostic structure is discuss...

To enhance power supply reliability for the user terminals in the case of the distribution system to avoid interference by the fault again, rapidly complete the automatic identification, positioning, automatic fault isolation, network reconfiguration until the resumption of supply of non-fault section, a microprocessor-based relay protection device has developed. As the fault component theory i...

In this study, the application of Bayes networks and fault tree analysis in reliability estimation have been investigated. Fault tree analysis is one of the most widely used methods for estimating reliability. In recent years, a method called "Bayes Network" has been used, which is a dynamic method, and information about the probable failure of the system components will be updated according to...

Increasingly more electrical devices are being developed in modern aircraft and will result in an increase in airborne electronic equipment fed by power electronic converters. With aircraft power system being sizable, the logical structure of aircraft power distribution systems, which affects the stability of aircraft power system, is becoming more complex. In this paper, we establish a mathema...

The electric power industry is currently undergoing an unprecedented reform. One of the most exciting and potentially profitable recent developments is increasing usage of artificial intelligence techniques. The intention of this paper is to give an overview of using neural network (NN) techniques in power systems. According to the growth rate of NNs application in some power system subjects, t...

The SVC (Static Var Compensator) based on voltage source converter (VSC) is used for voltage regulation in transmission and distribution system. The SVC can rapidly supply dynamic VARs required during system faults for voltage support. The apparent impedance is influenced by the reactive power injected or absorbed by the SVC, which will result in the under reaching or over reaching of distance ...
