While much research has been done on multimedia compression and network resource optimization, multimedia delivery over wireless still entails the need for efficient network adaptive transmission and reception system. MIMO (Multiple input multiple output) systems offer parallel sub-channel transmission with tremendous increase in reliability and data rates over unreliable wireless channels. In ...

Subscriber service is not feasible in the construction of large-scale traditional networks with the aim of providing more services. The high distance between production and consumption requires the definition of a transmission network as a challenging intermediary. The cost of transmission network and the risk associated with it cannot be ignored at all. The idea of a microgrid, which began wit...

Green power is clean without pollution, such as solar and wind power. It has become a resolution to supplement the deficiency of today’s high cost/danger energy resources. A challenge is to integrate these distributed resources into the power grid. The high cost and voltage drop of running long transmission lines motivate the way to minimize the length by serializing their connections to load c...

The transmission line pulse method (TLP) is used to characterise the reliability of bolometric GaAs microwave power-sensors. Two degradation mechanisms are identified during the degradation process of the absorbing NiCr termination, in which the input power is converted into heat. Simulations and a material analysis have been performed in order to characterise the observed degradation mechanisms.

In power system transmission network, the problem of improvement in voltage profile is a task that must be evaluated in an ideal way. The paper presents a QueenBee -Assisted GA based optimization for improvement in voltage profile of power system transmission network. This algorithm has been used to evaluate power engineering optimization problems adopting desirable results than traditional tec...

This paper is divided into two cases to study the communication transmission equipment reliability in the state of the ice storm, according to the huge losses of power system communication caused by the ice storm. For the nodes or links which are not affected by the ice storm, we use the calculation with “the mean time between failures (MTBF)” and “the mean time to repair” (MTTR) to put forward...

This paper is aimed at analyzing the possible power options and configurations for remote locations in the oil and gas industry with the view of proposing a cost effect power supply option suitable for the different operational requirements at these remote locations. It reviews the different power options available and presents selection criteria for the optimum choice of power generation techn...

Reactive power plays an important role in supporting the real power transfer by maintaining voltage stability and system reliability. It is a critical element for a transmission operator to ensure the reliability of an electric system while minimizing the cost associated with it. The traditional objectives of reactive power dispatch are focused on the technical side of reactive support such as ...

In this article, a novel approach is presented for the determination of reliability importance measures in electric transmission systems implementing the Bayesian network. By this method, the Bayesian network associated with a given power system is first constructed where the generation units are assumed fully reliable and the required training data is provided by using the state sampling metho...

An electric utility’s main concern is to plan, design, operate and maintain its power supply to provide an acceptable level of reliability to its users. This clearly requires that standards of reliability be specified and used in all three sectors of the power system, i.e., generation, transmission and distribution. That is why reliability of a power system is always a major concern to power sy...
