Abstract
For analysis and assessment of AC corrosion effect and safety influence of UHV AC and DC transmission line in the same corridor in normal operation on adjacent buried oil and gas pipelines, this paper analyses source and object of electromagnetic interference based on related domestic and foreign standards and literatures. Engineering design calculation and evaluation methods are also given. With actual parameters, CDEGS software is used to simulate an engineering example of certain parallel 1000kV UHV AC and ±800kV UHV DC transmission lines crossing adjacent oil and gas pipelines. Results show that electromagnetic effects on adjacent pipes are mainly caused by AC line when UHV AC and DC lines are in the same corridor. In the example, interference voltage on the pipeline produced by harmonic current of UHVDC line is less than 1/5 of that produced by UHV AC line, because effective value of harmonic current of UHV DC line is quite small (no more than 20A).关键词
