Abstract The aim of the paper is to describe a portable, modular, and scaleable system for measuring concurrent acoustic transmission loss atmospheric characteristics. This has been developed specifically inform an effort improve ability implement high fidelity numerical predictions loss, particularly in acoustically complex outdoor ranges, such as those that occur coastal areas. Such broad pos...

A big step forward to improve power system monitoring and performance, continued load growth without a corresponding increase in transmission resources has resulted in reduced operational margins for many power systems worldwide and has led to operation of power systems closer to their stability limits and to power exchange in new patterns. These issues, as well as the on-going worldwide trend ...

A voltage transformer, as voltage signal detection equipment, plays an important role in a power system. Presently, more and more electric power systems are adopting potential transformer and capacitance voltage transformers. Transformers are often large in volume and heavyweight, their insulation design is difficult, and an iron core or multi-grade capacitance voltage division structure is gen...

The generation of trajectories for a biped robot is a problem which has been largely studied for several years, and many satisfying off-line solutions exist for steady-state walking in absence of disturbances. The question is a little more complex when the generation of the desired trajectories of joints or links has to be achieved or adapted online, i.e. in real time, for example when it is wi...

Smart Electricity is quickly developing as the results of advancements in sensor technology. The accuracy of a sensing device is the backbone of every measurement and the fundamental of every electrical quantity measurement is the voltage and current sensing. The sensor calibration in the context of this research means the marking or scaling of the voltage sensor so that it can present accurate...

As electricity demand continues to grow and renewable energy increases its penetration in the power grid, realtime state tracking becomes essential for system monitoring and control. Recent developments in phasor technology make realtime dynamic state estimation possible with high-speed timesynchronized data provided by synchronized Phasor Measurement Units (PMU). In this paper we present a two...
