The invention of the phaser measurement unit (PMU) in mid 1980's enabled the synchronized measurements of voltages and currents in real time that has become the foundation of today's wide-area measurement, protection, and control (WAMP AC) systems. The trend in recent years is the steady increase of PMU installations worldwide for various applications, such as those targeted for State Estimation enhancement...
Recent power system blackouts around the world have driven attention to the need of wide area measurement, protection and control (WAMPAC) systems. Currently, the Brazilian electric power industry is making an effort, lead by independent system operator ONS, to implement a large-scale wide-area measurement system utilizing the synchronized phasor measurement technology. The system will be utilized...
Synchronized measurements represent next generation of paradigm-shift technology, enabling improvements in planning and operating electrical grid otherwise not possible. However, implementing a large-scale PMU system presents some unique challenges. Such systems need to transmit and store large amount of data. Deployment of this technology typically involves a large number of entities (utilities in...
Building new transmission facilities are becoming more difficult due to political and environmental pressures from the public and government. New transmission circuits are required to be built underground as far as possible to minimize visual and electromagnetic filed impacts on the communities in close vicinity of the new transmission facility. Several utilities are faced with challenges to interconnect...
