The Electric Field Analysis of the Warm Dielectric HTS Power Cable

The 75 m/1.5 kA AC high-temperature superconducting cable(75 m HTS cable) and the 360 m/10 kA DC HTS power cable (10 kA HTS cable), which are supported by Chinese State 863 projects, are both of the demonstration projects facing to industrialization application. The characteristic in structure of warm dielectric (WD) insulated HTS cable is introduced. The electric field distribution characteristic at the cryogenic envelope body, the end-point of metallic shield layer at the end of the HTS cable and the connection sections are analyzed; the controlling method for electric field stress is introduced; there is serious concentration of electric field both in the termination and the connection sections between the termination and the cryogenic envelope. It is difficult to calculate the electric field of the part with irregular or special structure by resolution analytical methods, and the numerical analysis method is effective to analyze the electric field of the shaped structural part for HTS cable. The electric analysis, simulation, the design and processing of insulation for the two cables are finished based upon these two cables run well by now.

Electric Field Analysis

Currently, there is little experience about design of the 1-tower-double-circuit DC transmission lines. But the electromagnetic field distribution under its lines is complicated. In order to study the nominal electric field distribution of 1-tower-double-circuit DC transmission lines under different situations and a variety of operating conditions, the currents with analytical solutions are used to simulate the discrete or uneven distributed continuous charge. In the works within an acceptable range, the linear equations are built to solve simulation charge according to the electromagnetic theory. And ground nominal electric field of 1-tower-double-circuit DC transmission lines is calculated. The nominal electric field distribution extreme value extreme under different arrangements and nominal electric field distribution under a variety of operating conditions are analyzed comparatively. In this paper, the results show that the arrangements of lines have effects on the distribution characteristics of nominal electric field in normal condition. When monopole or bipolar or the bipolar of one line doesnt work, the change of nominal electric field is pronounced, but their extremes reduce.

±1000kV DC wall bushing is a complex insulation system working in different conditions, such as DC, AC and polarity reversal. No matter what kind of conditions, the space charge effects on the electric field distribution of the bushing are remarkable. A finite element model for ±1000kV DC wall bushing is established based on space charge theory, to analyze the electric field distribution in different conditions, especially when polarity reversal occurs. The research results provide useful references for the electric field analysis and insulation optimization of UHV (ultra high voltage) DC wall bushings.
