220kv UHVDC reclamation unit

220kv UHVDC reclamation unit

The current research results indicate that the insulator's insulation performance has a very important influence on the back-flashover lightning withstand performance of UHVDC transmission lines, especially for ±800 kV voltage level. However, it is not clear which factors will influence the insulation performance of the insulator, and the influencing mechanism is also not clear yet.

  • UHV Transmission Technology | ScienceDirect

    Abstract. In terms of overvoltage and insulation coordination, a UHV system is similar to an extra-high-voltage (EHV) system. However, as UHV system lines are characterized by a larger transmission capacity, longer transmission distances, and large reactive power (the reactive power per 100 km of 1000-kV lines reaches up to about 530 Mvar) such that: (1) load rejection may cause serious
