【摘要】：伴随着河南500千伏输电线路规模的不断扩大,输电线路在运行过程中发生故障也在增多。近年来500千伏姚双线保持了较好的运行状况,在设计和运行方面有很多对线路可靠供电有益的方法和措施,对500千伏姚双线运行情况进行分析,研究设计和运行中有益的措施,由此提出整个500千伏线路的事故预防和治理措施,供500千伏输电线路建设和运行参考,有益于线路的安全稳定运行。本文所完成的主要工作包括：(1)500千伏姚双线基本情况的介绍。包括500千伏姚双线采用的设计标准、材料等情况的阐述。(2)500千伏姚双线故障案例的分析研究。对2000年以来500千伏姚双线发生的故障进行分析研究,找出故障发生的原因,针对性地提出故障治理措施。(3)500千伏姚双线运行情况分析研究。对500千伏姚双线防污闪等情况进行分析,结合500千伏姚双线设计和运行情况分析线路能够有效避免故障、保持可靠运行的原因。(4)总结输电线路反事故措施。结合500千伏姚双线运行情况的研究分析,提出输电线路在设计、建设、运行阶段的反事故措施和建议,从而能够有效确保线路的可靠运行。
[Abstract]:Along with the continuous expansion of Henan 500 kV transmission lines, transmission lines in the operation process has also increased the number of failures. In recent years, 500 kV Yao dual line has maintained a good operation situation. In the aspect of design and operation, there are many beneficial methods and measures for reliable power supply of the line. The operation situation of the 500kV Yao dual line is analyzed, and the beneficial measures in the design and operation are studied. Therefore, the accident prevention and treatment measures for the whole 500kV transmission line are put forward, which can be used as a reference for the construction and operation of 500kV transmission line. It is beneficial to the safe and stable operation of the line. The main work accomplished in this paper includes the introduction of the basic situation of the two-line lines of 1, 500 KV Yao and the design standard used in the 500 KV Yao dual-line. Analysis and study on the case of 500kV Yao double-line fault from 2000 to find out the cause of the fault. This paper puts forward the measures of fault treatment. It analyzes and studies the operation of 500 kV Yao double line and analyzes the situation of preventing pollution flashover of 500 kV Yao double line. Combined with the design of 500 kV Yao dual line and the analysis of operation condition, the circuit can effectively avoid the fault. The reasons for maintaining reliable operation are summarized. The anti-accident measures of transmission line are summarized. The design and construction of transmission line are put forward based on the research and analysis of the operation of the 500kV Yao double line. The anti-accident measures and suggestions in the operation phase can effectively ensure the reliable operation of the line.
