同杆跨线故障的选相及其单回线故障测距的研究
|
摘要
同杆并架双回线所需出线走廊窄,单位走廊输送能力强,节省投资,从而越来越多地在电力系统中采用。考虑平行双回线零序互感的影响,提出了一种基于故障线双端电气量的单线故障测距算法。该算法在原理上与过渡电阻和系统阻抗无关。本文利用六序故障分量法分析了零序负序电流选相元件和相电流差突变量选相元件在同杆双回线跨线故障下的动作行为。根据同杆双回线跨线故障时故障相电流相位特征,结合阻抗方向元件,提出了一种基于稳态量的综合选相元件,保护利用分相式通道在判断两侧选相结果后实现选相跳闸。最后从理论上分析了同杆并架双回线跨线故障时距离继电器测量阻抗的变化规律。
The double circuit lines on the same tower requires narrow corridors, the transmission on ability is strong, and investment is saved. Thereby, it is used by power system more and more. Considering the zero sequence mutual inductance, a novel accurate fault location algorithm using two terminal for double circuit lines on the same tower is presented in this paper, this method eliminate the influence of source impedances and fault resistance. Used the six sequence fault component, the action of some phase selectors were analyzed in this paper. Based on the future of degrees between fault phase for cross country fault and the directional component, a synthesis fault selector using steady values for double circuit lines on the same tower is proposed. With the multi phase channels and fault phase selection results at both sides, the relay may cut off the fault phases. In addition, the rule of variations measuring impedance of distance relay when cross country faults occurs between the double circuit lines on the same tower.
