With the advancement of sensor, communication and information technologies, Wide Area Monitoring, Protection and Control (WAMPAC) systems have been identified as the new generation of solutions to improve power system planning, operation and protection. There are a number of Southern California Edison (SCE) advanced initiatives that are related to the WAMPAC systems. Despite differences among various...
With the advancement of sensor, communication and information technologies, Wide Area Monitoring, Protection and Control (WAMPAC) systems have been identified as the new generation of solutions to improve power system planning, operation, and maintenance. With huge amount of real-time data collected through distributed sensors deployed in a wide area, effective information presentation has become...
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...
Phasor Measurement Units (PMU), based on the synchronized measurement technology, are basic building blocks of wide-area monitoring, protection and control (WAMPAC) systems. The overall system performance of such WAMPAC systems highly relies on the proper functioning of all PMUs of the system that conform to the same high performance standards. However, ensuring a uniform performance compliance of...
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...
