摘要
特高压输电工程建设能够满足我国未来快速的电力增长需求,满足电网规模逐步扩大、跨区联网基本形成的网络联结要求。该文介绍了特高压输电技术在国内外的研究现状,基于中国的实际情况,分析了中国1000kV特高压交流输电工程和±800kV特高压直流输电工程中,过电压与绝缘配合、外绝缘特性、电磁环境以及特高压设备制造与检验、检测等方面面临或亟待解决的问题。分析认为,依托国家电网公司一流的特高压交流试验基地和特高压直流试验基地,上述问题可以得到很好的研究解决,得到试验数据和分析结果可直接用以指导我国特高压输电工程的设计和建设。
UHV transmission projects can suffice the quickly increased demand of electrical power in the future, and suffice the requirement of grids extenting and uniting with the sustaining development of power system in China. The present paper introduces the research actuality of the whole world on UHV transmission project. Accoring to the analysis of chinese actual conditions, the some technical problems in both 1000 kV UHVAC and ＋800 kV UHVDC power transmission projects, including the problems of over voltage and insulation dependence, external insulation characteristics, electromagnetic environmental and the standards of UHV equipment＇s manufacture and test. Along with the come into being of the State Grid UHV AC test base and the State Grid UHV DC test base, the above problems can be correctly solved. Test results can be used to direct the designs and the constructions of UHV transmission projects in our countries.
