Abstract
In this paper
technical scheme of DC de-icing and SVC(static var compensator)is designed with combination of the actual requirement of 500 kV Guanshan substation; the basic structure
principle
function and operation mode of the DC de-icing and SVC device is introduced; and part of line in the technical scheme is simulated through the electromagnetic transient simulation software PSCAD/EMTDC of power system. It is shown by the simulation result that the ice-coating problem of long distance HV line is solved effectively and also the support ability of the power voltage is improved by the DC de-icing and SVC device.
