摘要电晕起始电压是高压直流输电工程电晕控制的依据,提出了一种基于电场特征集和支持向量机的起晕电压预测新方法。采用提出的方法预测了负直流导线的起晕电压,将预测值与试验值以及现有方法的计算值进行了对比,证明了所提方法的有效性和优越性。对±660kV换流站阀厅内均压球的起晕电压进行了测量和预测,得到了均压球表面的电晕起始电场强度控制值,通过对比电场有限元数值计算结果,证明了均压球在阀厅运行环境中不会起晕。该方法为高压直流输电工程导线和阀厅金具的电晕起始电压预测提供了一条可能的新途径。

Abstract：Corona onset voltage is the basis of corona control in HVDC transmission projects. A new method based on electric field features and support vector machine (SVM) is proposed to predict the corona onset voltage. The negative DC corona onset voltages of conductors were predicted, and the results were compared with those from the experiments and the existing methods. Thus, the effectiveness and superiority of the proposed method were validated. Then, the corona onset voltages of shielding spheres in a ±660kV DC converter station valve hall were measured and predicted. The electric field control values without corona on shielding spheres were obtained. By comparing with the electric field numerical results calculated by finite element method, it was proved that corona would not incept on the valve hall shielding spheres. This method supplies a new possible way to predict corona onset voltages of conductors and valve hall fittings in HVDC transmission projects.

Key words： DC corona corona onset voltage conductors valve hall fittings electric field features support vector machine
