摘要
为适应西电东输的能源传输战略,超特高压直流输电技术的发展将是必然趋势.直流互感器是超特高压直流输电工程中的重要设备,对保证超特高压直流输电系统的安全稳定运行具有重要作用.首先介绍了直流输电技术的发展进程,进而重点对直流电压互感器的测量原理进行了详细介绍.测量误差是直流电压互感器最重要的性能指标,对直流电压互感器测量误差的产生因素进行了分析,并给出了相应的改进措施和研究方向,为直流互感器的国产化研制奠定基础.
In order to meet the energy transmission strategy, UHV DC transmission technology will be an inevitable trend. that is, electricity transmission from West to East China, EHV/ DC transformer is an essential equipment of EHV/UHV DC trans- mission project, and it plays an important role in EHV/UHV DC transmission system for its safety and steady operation. The de- velopment of HVDC technology is introduced firstly, and then the measurement principle of DC potential transformers is intro- duced in detail. Measurement error is the most important performance indicator of DC potential transformer, so the reasons why the measurement errors of DC potential transformer occur are analyzed, and the corresponding measures for improvement and research direction are given, which lays the foundation for the localization development of DC transformer.
