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

The Journal of Engineering, 2019 The current source converter (CSC)‐HVDC system is the key technology for long distance large power transmission. However, the traditional CSC‐HVDC has two serious shortcomings: (i) vulnerable to commutation failures; and (ii) not being able to control its reactive power.

Mesh‐Based Charge Simulation Method and Its Applications to Electrostatic Electric Field Computation
High Voltage, EarlyView.ABSTRACT The charge simulation method (CSM) is a well‐established numerical technique employed in electrostatic field calculations, primarily due to its simplicity and computational efficiency. However, conventional CSM face challenges when applied to complex geometries, as they necessitate meticulous manual placement of simulation charges and matching
