摘要:
直流换流站高压设备金具表面电场的准确计算有助于电晕控制以及防电晕设计。针对换流站直流场设备复杂、计算区域大、对特殊金具局部表面电场计算精度要求高的特点,以某±500 kV换流站直流场为研究对象,基于电场数值计算方法,建立3D有限元仿真模型,对整个直流场设备进行电场计算,获得了各部位的电位和电场分布计算结果。通过对全模型计算结果进行分析,对其中需要重点关注的部位采用了子模型进行了更精确的求解,获得了更加准确的电场强度数值。最后基于Peek公式对直流场各金具进行了电晕控制安全裕度的评估,结果表明直流场各金具表面最大场强符合电场控制要求,研究结果可为超、特高压换流站直流场的设计、规划提供参考。
Abstract:
The accurate calculation of the surface electric field on equipment fittings in HVDC converter station will help to make corona control and anti-corona design. For HVDC converter station field is of complicated equipment, large computational domain, high precision of special fittings local surface field computing, a ±500 kV HVDC converter station field is taken for the study. Based on field numerical calculation method, 3D finite element simulation model of the entire DC field equipment is built for field computing, and the calcula-tion of various parts of the potential and the electric field distribution is obtained. Through the results of the full model analysis, the parts which need to be focused on are more accurate solved by the use of sub-mod-els, and a more accurate value of the electric field strength is gotten. Finally, based on the Peek formula, the corona control margin of safety assessment for all fittings in DC field is made. Results show that DC field with each fittings surface electric field control of the maximum field strength in line with the requirements, the results can provide reference to the design and planning of extra-and ultra-high voltage direct current converter station.
