摘要

国家电网公司特高压直流试验基地的重任之一是开展特高压直流输电的电磁环境研究

为我国特高压直流示范工程的建设和运行提供技术支撑。为保障试验线段上开展的电磁环境研究不受影响

作为试验线段主电源的1200kV特高压双极直流发生器本身的电晕控制十分重要。笔者结合该发生器的设计

采用有限元法建立其表面电场计算模型

分析其电场分布特征、规律和影响因素

并提出优化电场分布措施

为该发生器的设计和建设提供了依据。

Abstract

The ultra high voltage（UHV）DC test base of the state grid corporation of China plays an important role in Chinese UHVDC transmission technology development.One of the tasks of this test base is to carry out research on the electromagnetic environment impact of UHVDC power transmission and provide technical support for the construction and operation of the UHVDC demonstration project.The 1 200 kV bipolar UHVDC voltage generator is the main source of the experimental lines in the test base

and its corona control is very important for the guarantee of the quality of electromagnetic environmental research.The corona level of the generator depends on its surface electric field.This paper presents a FEM simulation model for the generator and investigates the characteristics of the surface electric field intensity distribution of the generator.Based on the simulation analysis

some shielding measures are provided to optimize the electric field distribution. The results of the research are applied in the design and construction of the bipolar UHVDC generator.The operation result shows that the corona level of the generator is effectively controlled.
