AIS电站隔离开关操作产生的空间瞬态电磁场特性分析
Analysis of the Spatial Transient Electromagnetic Field Charcateristics Generated by the Operation of AIS Disconnector
摘要
Abstract
With the construction of robust smart grid,the issue of spatial transient electromagnetic disturbance caused by the operation of disconnectors in air insulated substation(AIS)has become increasingly ctrtical.Most of the researche on electromagnetic disturbance both at home and abroad is focused on the measurement at a specific point in a certain substation.Relevant research shows that the current China National Standards are unable to effec-tively conduct experimental evaluations of the relevant electromagnetic compatibility characteristic of various second-ary equipment.Based on 330 kV real simulation experiment platform,in this paper the distribution characteristics and influencing factors of the spatial transient electromagnetic field generated by the operation of the disconnector in AIS power station,such as the closing phase of disconnector,residual voltage of line,length of bus,and parameters of other equipment,are studied.The research results show that the transient electromagnetic disturbance generated by the disconnector in AIS is multiple independent and non intersecting attenuation pulses.In case of arcing of discon-nector,the near-field electric field is mainly the Coulomb electric field generated by the voltage.The near-field magnetic field is mainly produced by loop current.The maximum attenuation velocity of Coulomb electric field is 128 kV·m-2.The overall attenuation speed of the induced magnetic field is not significantly different.The closing phase of the disconnector,the residual voltage of the line and the circuit impedance are the main influence factors of the characteristics of the space transient electromagnetic field.The frequency and intensity of spatial electromagnetic field is decreased with the increase of length of bus.The intensity of spatial magnetic field is increased with the increase of length of bus.关键词
