Power oscillations are a growing concern among power system operators worldwide. Traditionally, the main countermeasure against dangerous power oscillations has been the installation of power system stabilizers (PSS). Essentially, the potential for inter-area power oscillations depends on the strength of the tie lines between different areas and the load on the ties. From a European perspective...

This paper presents a frequency monitoring system for Korean wide-area power protection based on virtual FDR. The virtual FDR is introduced to enhance the simulation capability of frequency monitoring systems and consists of three parts: modeling, estimation, and simulation. Once a power grid model is obtained in the virtual FDR based on EMTP-RV, the frequency is estimated by DFT filtering and ...

The main cause of wide-area disruptions in the present power network is due to the relatively long transmission lines between regions, the continuous load growth without a corresponding increase in transmission network capacities. This disturbances have stressed power systems further and forced them operate closer to voltage and angle instabilities. As a result, stability of such power systems ...

This paper presents an efficient procedure for calibrating a wide area system of synchronized cameras with respect to a global coordinate system. The flexibility of this procedure lies in its use of a hand-held calibration target that is automatically detected in real-time by the system, and also in its capability to provide a feedback on the working volume coverage through a sampling pyramid. ...

This paper presents the fault detection technique in wide area power system network using Phasor Data Concentrator (PDC). Single line to ground (SLG) fault data of transmission line is processed using the WAMS technology. Phasor Data Concentrator (PDC) is primarily data collecting centres located at the control centre processing unit and is responsible for collecting all the PMUs data that is t...

A smart grid requires the implementation of ICT technologies in order to incorporate new functions into electricity grid monitoring and control. Wide Area Monitoring Systems (WAMSs) are used to measure synchrophasor data at different locations and give operators a near-real-time picture of what is happening in the system. The measurement data is periodically collected via communication channels...

For century, there has been no change in the fundamental structure of the electrical power grid and vehicle networks. Current hierarchical, centrally controlled grid of the electrical grid is not best for growing demand. To address the challenges of the existing power grid, the new concept of smart grid and smarter planet are under research. The smart grid can be considered as a modern electric...

This paper describes an algorithm for the coordination of a flock of multirotor UAVs which cooperate in performing a wide area monitoring mission. The key characteristics of the proposed approach are the self-organising ability and the decentralisation. The flock has the basic task of covering a certain area of terrain and is able to self-organise in order to (i) find a coverage of the area whi...
