With the improvement of electric information, 3D visualization for the substation in the planning, designing, inspection, training and other aspects calls for a gradual increase. 3D rendering of the current technology is not yet mature, and equipment modelling is too complex, we propose a virtual 3D substation, which is an image-based system. The key issues include a spherebased methods of fish...

From a safety and security point of view, the electrical energy distribution infrastructure needs to be protected.. In this paper solutions to increase the safety aspects of substation components, power lines and power transformers are discussed. Also security solutions related to perimeter intrusion detection in substations and remote surveillance of power transformer installations are introdu...

We present results from an experiment where the effects of automatic flow control at a single substation is compared to automatic cooperative concurrent flow control at multiple substations. The latter approach is made possible by equipping individual substations with some computing power and integrating them into a communications network. Software agents, whose purpose is to cooperate with oth...

In this paper, power distribution planning (PDP) considering distributed generators (DGs) is investigated as a dynamic multi-objective optimization problem. Moreover, Monte Carlo simulation (MCS) is applied to handle the uncertainty in electricity price and load demand. In the proposed model, investment and operation costs, losses and purchased power from the main grid are incorporated in the f...

Finding the reliability expression of different substation configurations can help design a distribution system with the best overall reliability. This paper presents a computerized a nd implemented algorithm, based on Disjoint Sum of Product (DSOP) algorithm. The algorithm was synthesized and applied for the first time to the determination of reliability expression of a substation to determine...

modern integrated circuits consist of millions of standard cells and routing paths. in nano-scale designs, mis-prediction is a dominant problem that may diminish the quality of physical design algorithms or even result in the disruption of the convergence of the design cycle. in this paper, a new planning methodology is presented in which a master-plan of the chip is constructed at the early le...

Introduction: Recent industrial developments in human societies have caused rapid advancements in technologies of production and distribution of electricity, which in turn result in enhancement of power networks and utilization of high voltages. These networks and the high voltages in transfer lines cause the exposure to electric and magnetic fields. In this study, the situation regarding the m...

The ability to transfer load currents between parallel busbars is one of the main requirements for most disconnector switches in gas insulated as well as air insulated substations today. As such, the capability limits and testing methods are internationally standardized in IEC 62271-102. The test circuit dictated in this standard is the Thévenin equivalent of the high current, power frequency a...

A unified specification to design and operate the stability control device in smart substation has not been formed yet, which greatly affected promotion application of substation. Thus, referring technical specifications protection combining specificity device, a full detailed configuration scheme is proposed meet requirement, including principle, access SV GOOSE for variable primary connection...
