ABSTRACT The ± 200 kV direct current (DC) cables of the Zhoushan Transmission Project were targeted, and crosslinked polyethylene (XLPE) insulation samples were prepared from faulty and spare cables. Samples were tested for oxidation induction period, Fourier transform infrared spectroscopy, differential scanning calorimetry, thermally stimulated ...

Ann based Shortcoming Area in HVDC Transmission Line
This paper is to ponder the use of Neural systems for shortcoming discovery and area in HVDC framework. The proposed Neural system learns examples and relationship on transient information. The Back-propagation algorithm has the ability to match map complex and nonlinear input - output behavior.

HVDC-Transmission Line Model for Transient Simulation Purposes
Abstract A lumped bipolair HVDC-transmission line model, based on least squares fitting of orthogonal polynomials, which are space dependent, and have time dependent coefficients, is presented and examined in this paper. The model enables the line voltage and current to be approximately determined for arbitrary points along the line and at arbitrary ...
