同杆多回线序分量法的推广

同杆并架多回线是未来发展的趋势。在研究同杆2回线和4回线的基础上,提出了一种用序分量解决同杆n(n=2、3、4)回线的通用方法。该方法使用矩阵变换对n回线进行解耦,形成相互独立的3n个序分量,并根据这3n个序分量的特点,给出了线路发生故障时的各序分量图。该推广方法的提出,为同杆多回线的故障计算提供一种分析方法。理论分析表明了该通用方法的正确性

Generalization of sequence component method of multi-parallel lines on same towers

N-parallel line on same tower is the development trend of the future in power system.On the basis of studying two- parallel line and four parallel line on same tower,in order to solve the problem existing in multi - parallel line on same tower,this paper presents a universal method which uses 3n - sequence component method to decouple multual delctromagnetic effect between n - parallel transmission lines.The 3n - sequence components are independent from each other.The characteristics of the 3n - sequence components are studied and the related sequence networks are introduced..An analysis of calculation methods for fault caculation can be selected,as the promotion of methods proposed.Theoretical analysis shows that the common method is correct.
