Energy Science &Engineering, EarlyView.Bipolar configuration is a new topology in the direct current (DC) system of photovoltaic power plants, which is topologically analogous to the bipolar configuration utilised in High‐Voltage Direct Current power transmission systems. DC cable length and copper usage are reduced by 50% using a bipolar configuration.

Hybrid HVDC for supply of power to offshore oil platforms [PDF]
, 2004 A HVDC hybrid system, comprising a line commutated thyristor HVDC converter and a STATCOM, is proposed in this paper for supplying power to offshore oil platforms that do not have their own generation. The proposed system combines the robust performance,

Journal of Plant Nutrition and Soil Science, EarlyView.During regular operation of the SuedLink at a load ≤75 %, the average increase in temperature in the plowing horizon is expected to be less than 1.6°C in the soils along the route in Southwest Germany. ABSTRACT Background The SuedLink was planned as a high‐voltage direct‐current underground cable route. The construction itself is a massive intervention

Dynamic Behaviour of Bubbles in Oil Under Electrothermal Ageing
High Voltage, EarlyView.ABSTRACT During long‐term operation of converter transformers, the internal oil–pressboard insulation undergoes irreversible degradation. Partial discharge in the weakened insulation will cause the formation of a large number of bubbles in the insulating oil.
