Abstract

Flexible HVDC transmission has the characteristics of flexible operating power range, simple power direction control, independent operation, and superior transmission performance. The synchronous operation stability does not limit its conveying capacity and conveying distance, and also avoids the influence due to low frequency oscillation. The systems with the same or different rated frequencies can be connected in parallel, so that they work according to their own voltage and frequency, do not need to run synchronously, and are not affected by the network, so if a fault occurs, it will not cause a large-scale power outage and reduce losses. Therefore, HVDC transmission has received increasing attention. In this paper, a coupled simulation of the main physical field—electric field and temperature field of the HVDC cable terminal is carried out, to explore the influence of temperature on the electric field distribution of the HVDC cable terminal, and to provide a basis for cable design and actual conditions.

直流电缆温度场和电场的研究与分析

柔性直流输电具有运行功率范围灵活、功率方向控制简单、运行独立、传输性能优越等特点。同步运行的稳定性不限制其输送能力和输送距离，也避免了低频振荡的影响。额定频率相同或不同的系统可以并联，使它们按照自己的电压和频率工作，不需要同步运行，也不受网络的影响，所以如果发生故障，不会造成大规模停电，减少损失。因此，高压直流输电越来越受到人们的重视。本文对高压直流电缆终端的主要物理场-电场和温度场进行了耦合仿真，探讨温度对高压直流电缆终端电场分布的影响，为电缆设计和实际工况提供依据。
