Simulation Analysis of Effectiveness of Radio Interference Measurement on Test Line
摘要
Abstract
With the improvement of voltage levels,radio interference caused by transmission line has attracted much attention.Test line can be directly used to study the transmission line radio interference characteristics,which provides a reliable basis for engineering design,and it has been more widely used at home and abroad.Which is different from actual transmission line at the connecting ends,test line radio interference current produced by corona will reflect at the end,and measurement results can＇t be directly applied to practical circuit.So we need to study the radio spectrum relationship between short and long lines,to ensure that test results and data analysis method is reliable.The model in this paper is based on the radio interference current spread mechanism,and the simulation results show the effectiveness of radio interference measurement on test line.It also gives the methods of measurement and data analysis of the radio interference on test line,the equivalent of different terminals（open circuit,short circuit,capacitors） and the impact of measuring points.These methods can be used to measure radio interference currents and space radio interference.The averaged envelope of spectrum on the short-term maximum and minimum values is the actual transmission line radio interference spectrum with same corona current circumstances.关键词
