Study of Zhebei-Huxi 1 000 kV AC Transmission Line Frequency Parameter Anti-interference Test
The paper investigates the run parallel line states of the Zhebei-Huxi 1 000 kV UHC AC transmission line.Using of sections coupled frequency interference calculation model,the electromagnetic interference current and the electrostatic induction interference voltage are calculated.To ensure the line frequency parameter test safety at work,the anti-interference method is proposed.
