Analysis and simulation on voltage distribution of HVDC thyristor valves under a variety of voltage stress are performed respectively. The summarized influencing factors on voltage distribution indicate that they are different with frequency. Due to the importance and difficulty in approaching even distribution in high frequency, the voltage distribution with different module structure and different...
Wind energy is the most important type of renewable energy in Europe. The stability of system network operation with a large penetration of wind energy has become one of the most critical issues in the new structure of power systems with different types of generation. In this paper the HVDC and HVAC connection of the wind farm to grid is compared. The HVDC is more advantageous in maintaining the system...
As one of the renewable and clean energy resources, wind power is attracting considerable attention and becoming most developing renewable energy resources due to its large unit capacity, etc. However, in some areas of the world, such as in Japan, there are some geographical and electrical restrictions for land wind generation. Since few suitable construction sites can be found and the power system...
