摘要
简要介绍了局部同塔输电线路的架设方式,对比了局部同塔输电线路、完全不同塔输电线路、完全同塔输电线路的故障特征。在此基础上,重点研究了局部同塔输电线路不同故障位置和架设参数对零序电流保护的影响,并提出了相应的改进措施。仿真结果证明了理论分析和所提措施的正确性和有效性。
The erection modes of power transmission lines partially on same tower are briefly introduced and the fault characteristics are compared among power transmission lines totally,partially and none on same tower,based on whieh,the influences of hull loeation and ereetion parameters on the zero-sequenee current protection for the power transmission lines partially on same tower are researched and the improving measures are proposed. The simulative results show the correctness and effectiveness of theoretical analysis and the proposed countermeasures.
