1. Data Quality in Wide-Area Monitoring and Control Systems : PMU Data Latency, Completness, and Design of Wide-Area Damping Systems
Sammanfattning : The strain on modern electrical power system operation has led to an ever increasing utilization of new Information Communication Technology (ICT) systems to enhance the reliability and efficiency of grid operation. Among these proposals, Phasor Measurement Unit (PMU)-based Wide-Area Monitoring and Control (WAMC) systems have been recognized as one of the enablers of “Smart Grid”, particularly at the transmission level, due to their capability to improve the real-time situational awareness of the grid.

3. Aspects of Wide-Area Damping Control Design using Dominant Path Synchrophasor Signals
Sammanfattning : The presence of inter-area oscillations has long affected stability constraints, and therefore, limited the power transfer capacity of interconnected power systems. Adequate damping of these inter-area oscillations is, thus, necessary to secure system operation and ensure system reliability while increasing power transfers. LÄS MER
4. Methods for Synchrophasor-Based Power SystemInstability Detection and HVDC Control
Sammanfattning : The recent availability Phasor Measurement Unit (PMU) functionalities in relay technology has opened up new opportunities for power system protection, allowing this microprocessor-based technology to be used beyond traditional protection purposes. This technology now also considers the computation and communication mechanisms that allow the transmission of synchronized phasor measurements. LÄS MER
