【摘要】：在相同感應(yīng)地電場(chǎng)作用下,高電壓等級(jí)輸電線(xiàn)路的地磁感應(yīng)電流(geomagnetically induced currents,GIC)比較大,交流特高壓電網(wǎng)建設(shè)使我國(guó)電網(wǎng)增加了1 000 k V電壓等級(jí),綜合考慮線(xiàn)路長(zhǎng)度、單位阻值等GIC影響因素,準(zhǔn)確計(jì)算我國(guó)1000k V特高壓電網(wǎng)的GIC是重要研究課題。以我國(guó)三華特高壓電網(wǎng)為例,只考慮1 000 k V電壓等級(jí)網(wǎng)絡(luò),建立GIC模型,計(jì)算了東向及北向感應(yīng)地電場(chǎng)情況下特高壓電網(wǎng)變電站及輸電線(xiàn)路的GIC。計(jì)算結(jié)果表明,我國(guó)特高壓電網(wǎng)1 000 k V變電站中受GIC影響最大的變電站有錫盟,上海等特高壓變電站;另外我國(guó)特高壓電網(wǎng)輸電線(xiàn)路中GIC規(guī)劃計(jì)算數(shù)據(jù)偏大的有石家莊—濟(jì)南線(xiàn)路和南陽(yáng)—長(zhǎng)治(晉東南)線(xiàn)路等,應(yīng)引起電網(wǎng)公司對(duì)GIC災(zāi)害防治的重視。
[Abstract]:Under the action of the same induction electric field, the geomagnetically induced currents (GIC) of the high voltage grade transmission line is larger. The AC UHV power grid has increased the voltage level of 1000 K V in the power grid of our country, considering the GIC influence factors such as line length, unit block value and so on, and accurately calculating the 1000K V UHV power grid in China GIC is an important research topic. Taking China's three Watt High voltage power grid as an example, only considering 1000 K V voltage grade network and establishing GIC model, the GIC. calculation results of UHV power grid and transmission line under the eastward and northward induction electric field show that the largest change affected by GIC in the 1000 K V substation of UHV power grid in our country. The power station has Xion, Shanghai and other UHV substations. In addition, the data of GIC planning and calculation in the transmission lines of UHV power transmission lines in our country are Shijiazhuang Ji'nan line and Nanyang Changzhi (Southeast Shanxi) line and so on, which should arouse the attention of the Power Grid Corp to the prevention and control of GIC disaster.
