Online condition monitoring of electrical power system imbalance
Symmetrical components are of great importance in many applications in electrical power systems, such as power protection and condition monitoring. This paper presents a computer-based algorithm for online symmetrical components estimation. The proposed algorithm uses the samples of the phase variables (currents or voltages) to estimate the magnitude and phase angle of each phase phasor at each ...

Cascade failures and distributed generation in power grids
Power grids are nowadays experiencing a transformation due to the introduction of distributed generation based on renewable sources. At difference with classical distributed generation, where local power sources mitigate anomalous user consumption peaks, renewable sources introduce in the grid intrinsically erratic power inputs. By introducing a simple schematic (but realistic) model for power ...

Solarthermal parabolic trough power plants with integrated storage capacity
Parabolic trough power plants use concentrated direct insulation for steam generation in a Rankine cycle. The fundamentals for direct steam generation in parabolic troughs have been developed in recent years, the feasibility was successfully demonstrated at a solar powered test facility reaching steam temperatures of 400°C at a maximum pressure of 100 bar. Important components for the accelerated ...

Physical properties of wood pellets from a novel pelletising process
In this paper a novel pelletising process is described utilising one-axial compression. Compression tests of saw dust samples were conducted at different applied forces, moisture contents, process temperatures and hold up times using a compression cell powered by an Instron testing machine. Additionally the effect of heating in saturated and unsaturated atmosphere was studied. The densities of ...

Star-hexagon transformer and non-isolated three-leg VSC based three-phase four-wire DSTATCOM
A new three-phase four-wire DSTATCOM (distribution static compensator) is proposed for power quality improvement in the distribution system. The DSTATCOM is based on a star/hexagon transformer and three-leg VSC (voltage source converter). It compensates harmonic current, reactive power and balances the load along with neutral current compensation. Each of the three single phase transformers has ...

New approaches in battery monitoring architectures, design and methodologies
The typical dilemma of a backup battery system user is whether to rely on the guarantees of a battery supplier with regard to product performance, or to independently monitor battery status to ensure reliable backup power when the power is needed. This dilemma has created a vague sense of mistrust between battery suppliers and end users. More and more end-user decision makers, however, are ...
