ELECTRIC POWER GRID AND MEASUREMENT TASKS IN THE EUROPEAN UNION

Abstract

Over the last years, the structures of electrical power supply changed noticeable. Centralistic conventional power generation is supplemented by distributed energy resources. Trends of energy demands let know that amount of solar and wind energy will progressively increase, very often with a relevant amount of distortion: this gives emphasis to power quality evaluation. Proper metering in non-sinusoidal conditions and, thus, large bandwidth transducers are required. Two different approaches to solve the problem of classical instrument transformers are proposed: one is substituting them with new low cost insulated electronic transducers, another is improving performances of the already installed IT, through the use of digital compensation devices. It has been proven that both the solutions solve the problems of high accuracy and large bandwidth, necessary for accurate measurements in new energy scenario.
