摘要
距离保护因良好的动作性能在中高压线路上得到广泛应用,但是同杆并架双回线间零序互感对距离保护的动作性能有严重影响。分析了同杆并架双回线零序互感对距离保护的影响,通过ATP-EMTP软件仿真了距离保护在同杆并架双回线上的动作行为,提出采用基于六相序的距离保护来解决这一难题。
Distance protection has been applied extensively in mid-high voltage electric power line for its excellent characters,but the zero sequence mutual inductance of double transmission line on same tower is fatal to the traditional distance protection.Firstly, this paper analyzes the influence of mutual induction upon distance protection,then the ATP-EMTP simulation software is used to analyze the action of traditional distance protection on the double transmission line in detail,lastly a distance protection based on the six phase sequence is proposed to solve the problem.
