ABSTRACT The problem of gas–solid interface charge accumulation is an important reason for distorting the surface electric field and then inducing surface discharge. The temperature gradient distribution formed on the spacer during the operation of a gas‐insulated transmission line (GIL) will aggravate the surface charge accumulation, further ...

Hybrid HVDC for supply of power to offshore oil platforms [PDF]
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,

The Area Comparison of LCC-HVDC and VSC-HVDC [PDF]
With the mature of high power IGBT, VSC-HVDC technique is gradually adopted in principle power grid with higher voltage and capacity. At present, it is generally considered that compared with traditional HVDC technique, VSC-HVDC will save lots of land resources. However, it is not always the case.
