Metrology for the Evolving Electric Power Grid
October 22 @ 4:00 pm - 5:30 pm
The operation of Power Systems relies on measurements of non-electric and electric quantities, which are essential for control, monitoring and protection. Among the measurements of electric quantities are voltage, current, frequency, active and reactive power and energy, and other derived quantities, under both sinusoidal and distorted voltage and current conditions. The revenue metering entails measurements of electric energy and power, and is important for power system economics. A concept of transactive energy combines economic and control techniques and is introduced and used for improving the efficiency and reliability of a more intelligent and interactive Power System. Smart Grid aims at the increase of efficiency, reliability, security, and integration of Renewable Energy Sources into the Power System. Smart Meters, with their two-way communications allowing for reading and control, are one of the basic tools for the Smart Grid introducing at the same time new dynamics into the system and raising privacy issues. With the proliferation of power electronics and increasing presence of Electric Vehicles (EVs) and EV Infrastructure, Power Quality measurements with increasing penetration of higher harmonics are necessary and widespread. In this talk, the measurements with and the calibrations of conventional voltage and current instrument transformers (ITs), electronic voltage and current transformers (EVTs and ECTs) and non-conventional instrument transformers (NCITs) will be discussed. Measurements of losses in power transformers, electrical machines and other equipment important for the efficiency of power transmission, as well as synchrophasor measurements used in for wide-area protection, control and monitoring (WAPCAM) and situational awareness will be discussed as <a href="http://well.
