According to the Regulation (EC) No 714/2009 ENTSO-E and the TSO Community strive for a secure, resilient, flexible, adequate and well interconnected pan-European power system, and they are acting unanimously to develop the most suitable responses to the challenges of the energy transition and digital transformation. The publishing of Summer and Winter Outlook, twice per year, […]
High-voltage direct-current (HVDC) technology is a growing field in the T&D sector, allowing transmission of bulk quantities of energy with a reduced impact on infrastructures and reduced losses. The performance level of today’s HVDC solutions allows to gain advantage from technical, economic and environmental points of view. HVDC power transmission becomes more and more […]
The reversal of voltage polarity is essential in HVDC cablesystems with Current Source Converters (CSC), since it enables to revert the direction of the power flow. Mass Impregnated Non-Draining (MIND) cables are known tobe able to withstand the voltage polarity reversal without particular problems. TERNA, the Italian Transmission System Operator (TSO), has introduced since many […]
The collection, storage and analysis of information concerning a dam are a critical part of surveillance activity toward managing the safety of the structure. An important part on handling of this information is the interpretation of data coming from the monitoring. In addition, the use of automatic instrumentation has resulted in large amounts of data […]
Optical partial discharge detection is a new method to perform diagnosis of the insulation system detecting optical signals which are coming up at the same time.This method does not work with the electrical signals which are caused in case of partial discharges though. On the basis of this different physical process, external electrical noise can […]
A long distance HVDC transmission link between Central Operating Area and Western Operating Area in the Kingdom of Saudi Arabia was planned and designed and it is currently under development. This 770 km long point-to-point link consists of two LCC type converter stations and it is embedded in a powerful AC network, where the two […]
