Power industry deregulation trend and proliferation of digital electronic devices are deeply affecting operations of power utility companies. Engineering departments, in particular, must deal with increasing complexity of existing applications as well as with emergence of new applications. Such an environment, creates many new challenges for protection system engineers. Use of new business mode...

In emergency and abnormal conditions, a power system operator has to deal with a large amount of data and apply most appropriate remedial actions. However, due to emotional and psychological stress, an operator may not be able to adequately respond to critical conditions and make correct decisions. Mistakes can damage very expensive power system equipment or worse lead to major emergencies and ...

The Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) is used to believe that a human is using the web service [1]. For the online services which are been provided in web services is been abused by automated bots over the internet. So CAPTCHA is used as a protection from these malicious programs for web security. But the bots are intelligent enough to break th...

Intelligent adaptive systems are sensitive to their environment, which enables them to address the complexity of modern software systems. As a result, they are able to adapt to changes in the environment autonomously. Numerous algorithms are available to provide adaptivity to the system. However, formal methods have not been widely used for specification and verification of adaptive systems. Ou...

This paper will propose a cascade of minimum description length criterion with entropy approach along with artificial neural network (ANN) as an optimal feature extraction and selection tool for a wavelet packet transform based transformer differential protection. The proposed protection method provides a reliable and computationally efficient tool for distinguishing between internal faults and...

For troop and military installation protection, modern computer vision methods must be harnessed to enable a comprehensive approach to contextual awareness. In this chapter we present a collection of intelligent video technologies currently under development at the General Electric Global Research Center, which can be applied to this challenging problem. These technologies include: aerial analy...

Recently there has been a considerable effort devoted to intelligent joint speech coding and iorward error correction (FEC) coding [I] as well as to equal [2] and un-equal protection coded modulation [3]. In reference [4] Hagenauer introduced an intelligent framework for considering source significance-, channel stateand decoder reliability-information in order to achieve the best possible perf...

Abstract In order to eliminate the influence of delay error sampled value in data link on longitudinal differential protection device, this paper proposes a self-healing synchronization algorithm based wavelet transform calculate moment sudden change. First, mutation amount at each end real time. When threshold is exceeded, it determined that multi-terminal system has short-circuit fault. Then,...

Abstract Maintaining the protection device and eliminating abnormal fault defects of are important tasks for maintenance power system. In general, relay equipment managers need to regularly check device. According usual practice, professionals use tester manually connect. The traditional verification method has complicated operation, high professional requirements testers. this paper, a set int...
