Ion Current Density

HVDC transmission lines can generate an effect on the environment nearby due to the electric field and the ion current density after the corona occurs, so the calculation of ionic flow field is significant to transmission lines design and electromagnetic analysis. However, there is no effective method to calculate the characteristic parameters of ionic flow field under rainy condition. Based on Deutschs assumption, a calculational method is proposed with considering the effects of raindrops on ionic flow field. In the method, the space-charge-free electric field distortion caused by raindrops is especially considered, and the charged raindrops are seen as a charge background of transmission lines. The field strengths and ion current densities calculated using this method are compared with the experimental results in the published literature, it shows that the method is effective and accurate enough under fair and rainy conditions.

Based on the technology of virtual instrument, a set of measurement system of the total electric field on the ground level under HVDC transmission lines is developed. After the hardware and software system are built up, some tests are made in laboratory to show the validity of the system. Finally, experiment results are given and analyzed. The developed measurement system can be used to measure the total electric field on the ground level under HVDC transmission lines, and can provide support for the evaluation of the electromagnetic environment of the HVDC transmission lines.
