摘要
对于特高压输电线路的设计而言,导线选择是一个重要课题。特高压输电线路导线选择的重点是研究导线对电磁环境的影响。皖电东送淮南—上海特高压输变电工程广德县末段30km输电线路的导线选型设计,就重点从导线对电磁环境的影响方面做分析研究。
首先根据特高压输送容量、负荷特性及国内外导线生产运行情况,选取6种线型,研究利用分裂导线降低输电线表面电场强度的原理,初步确定分裂根数,分别为6×JL/G1A-900、7×LGJ-800/55、7×ACSR-720/50、8×LGJ-630/45 9×LGJ-500/35、10×LGJ-400/35,并兼顾电气和导线的次档距振荡两个方面的特性,合理选取导线分裂间距；接着,应用加拿大SES公司的CDEGS软件中的SES-Enviro模块展开,分析比较导线的分裂数、子导线截面积、分裂间距、线间距离、对地高度对于导线表面电场强度、地面场强、无线电干扰和可听噪声的影响,从电磁环境影响的角度确定最佳的导线组合；最后,仍采用CDEGS中的SES-Enviro模块展开,分别对所选的6种导线结构的电磁环境特性做分析,计算Ⅰ串、Ⅴ串两种塔型,正、负两种相序下6种导线结构的导地线表面电场强度、离地1.5m处场强分布、无线电干扰和可听噪声,最终确定本次设计采用8×LGJ-630/45导线。
As for the design of ultra high voltage(UHV) transmission lines, the choice of conductors is one of the main problems. It is important that research influence of UHV transmission lines electromagnetic environment. It is important to analyze the influence by the electromagnetic environment to line.
Firstly, according to the transmission capability of UHV、the burden characteristic and the produce and circulation of line in domestic and international, six kinds of line type are selected. They are researched principle that is to decrease the surface electric field intensity of line. The first step is to define the types that are included: 6×JL/G1A-900、7×LGJ-800/55、7×ACSR-720/50、8×LGJ-630/45、9×LGJ-500/35、10×LGJ-400/35, Because of the characteristic of the electric and the next distance of line, abruption distance of line is reasonable selected. Then the best line combination is defined from the influence of electromagnetic environment through analyzing the number of abruption、the area of line、the distance of abruption、the distance between of the line、the surface electric field intensity of line、the electric field intensity of ground、radio inference(RI) and the influence of audible noise(AN), by using the SES-Enviro mold in CDEGS soft of Canada SES company. At last by using the SES-Enviro mold, analyzing the characteristic of electromagnetic environment of the six kinds of line, calculating the surface electric field intensity of line、the distribution that is 1.5 meter to the ground、the radio inference and the influence of audible noise of the six kinds of line in the two kinds phase of plus and minus,the 8×LGJ-630/45 type line is defined in the design.
