As Built Is Not Enough

摘要

Belgian TSO Elia selects ACCC conductors to double the load transfer capacity of a 150-kV line. The development of transmission systems is essentially linked to the economic development of regions, expanding electricity markets, and the need to provide and interconnect all forms of power generation. When seeking new rights-of-way, transmission system operators (TSOs), together with many other service organizations, often face increasing opposition due to environmental issues and the not-in-my-backyard syndrome. Therefore, innovative TSOs with considerable support from research organizations and manufacturers are using new technical solutions that minimize the environmental impact and remain compliant with national legislation and international design standards. When faced with this challenge, Elia, the Belgian TSO (which is also 100% owner and 60% operator of the German TSO 50Hertz Transmission), considered the use of established solutions such as increasing the line voltage, increasing the conductor cross-sectional area, real-time monitoring and using conductors with a higher conductivity. None of these solutions offered a satisfactory answer. To meet the growing demand for energy and guarantee network reliability, Elia had to search for a cutting-edge solution.
