Reactive power management and voltage control of large Transmission System using SVC (Static VAR Compensator)

The role of the transmission network in the Power System is to transmit the power generated in the power plants to the load centers and the interconnected power systems. The transmission of electric power has to take place in the most efficient way in addition to providing flexibility in the process. Flexible A.C. Transmission System (FACTS) promotes the use of static controllers to enhance the controllability and increase the power transfer capability. Providing reactive shunt compensation with shunt-connected capacitors and reactors is a well established technique to get a better voltage profile in a power system. Shunt capacitors are inexpensive but lack dynamic capabilities, thus some form of dynamically controlled reactive power compensation becomes essential. This feature is provided by Static VAR Compensator (SVC). The work presented here also compares SVC with fixed capacitor compensation and documents the superiority of SVC using Computer Simulation and its performance for reactive power management and better voltage control.

Copper cables: Should they be phased out as last mile broadband solutions?

The fundamental building block of last mile broadband connections for the telecommunications industry is the copper cabling systems that have traditionally underpinned the networks. Time has seen tremendous change in this core component of the network, with result being silica-based fiber optics are championed as the de facto replacement technology for traditional copper cabling in the last mile. This paper will provide a survey and discussion of the current status of copper cabling in networks. It will examine the strengths of copper verses fiber optics. It will explore the effectiveness of recent technological advances made in delivering broadband over copper. It will also review the current economic models relating to cable deployments. Finally, an analysis will be presented that attempts to answers the question of phasing out copper.

A dual band passive RFID design in 0.18µm CMOS technology

This paper presents a novel fully integrated passive X-band RFID transponder, implemented in IBM 0.18-μm RF CMOS technology. The tag was designed to keep the current dissipation in the whole system to a minimum, with special emphasis on RF-DC rectifier and the voltage sensor. Interaction between the building blocks of the RFID tag was investigated and the key design issues addressed in this paper include the design of low-power RFID building blocks. The simulation results demonstrated that the proposed low-power RFID transponder can properly operate under very low input power as well as complying with the universal RFID communication standard.

Interdependency modeling for survivability of Smart Grid and SCADA network under severe emergencies, vulnerability and WMD attacks

In this paper, we propose a flexible and extensible framework for network survivability based on interdependency modeling of Smart Grid and Supervisory Control and Data Acquisition (SCADA) network. We developed novel approach for vulnerability reduction considering both structural and functional vulnerability. We computed interdependent effect between these networks under different conditions. We used MATLAB for simulation and analysis for methodology developed by us for interdependency analysis. The contribution of this paper provides a feasible research approach for the normalization of network survivability testing and evaluation and the promotion of network survivability research.

Safety considerations for fixed-line and wireless network service

For the majority of the last century single service fixed-line based networks were the primary means of communications. Over the past few decades, we have seen tremendous change to the traditional fixed-line model including the introduction of wireless networks and a shift in focus from single-service to multi-service networks. These newer multiservice networks are designed to provide broadband via both fixed-line and wireless connections. All of this rapid change has resulted in very complex network management organizations and safety issues that are distinct to each network type. This paper will provide a survey and discussion of the safety issues that relate to fixed-line, fiber optics and wireless networks. It will examine how the infrastructure service model is drastically different between traditional fixed-line service providers and wireless service providers. Finally, it will explore issues and regulations relating to buried telecommunications plant.

Metamodeling of RFIC integrated inductors using ASITIC simulation data

In this paper, we describe a new method to generate lumped-parameter equivalent-circuit (EC) approximations for on-chip inductors. Nonlinear least-squares fitting is then applied to numerical data obtained from a very large number of single-time ASITIC runs for a given process. Results show significant improvement as compared to the published models. The proposed method should enable the optimization of inductor geometry.
