HVDC Classic - Hitachi ABB Power Grids increased interest in recent years for transporting clean and renewable energy from remote hydro generation plants has also increased the interest in higher DC transmission voltage than presently used (i.e. 600 kV DC). This has led to development of Ultra high voltage direct current (UHVDC) at 800 kV and more recently even up to 1,100 kV DC.
Converter Transformer - an overview | ScienceDirect Topics Power station units with full-size converters. Power station units with full size converters such as type 4 wind turbines and solar PV converter-transformer station units are modelled in the positive-sequence system as a current source. The current is provided by the manufacturer. The positive-sequence shunt impedance is assumed infinite.
Power Transmission | Offerings | Siemens Energy Global for future tasks Various factors will dominate the power transmission market in the years to come: the drive toward renewable energy, the expansion and interconnection of grid infrastructures, and the need to gradually replace and upgrade aging grid infrastructures.
Fire Protection in Substation Transformers | T&D World suppression is defined as the sharp reduction in the heat release rate of a fire and the prevention of its regrowth by a sufficient application of water mist. Unlike a water spray system that is designed strictly as exposure protection, the water mist system is a fire suppression system.
