陕北750/330kV主网架规划研究

Study on Northern Shaanxi 750/330 kV Main Power Grid Planing

"十一五"后三年是西北750 kV电网跨越式发展的重要时期。陕北电网作为西北电网的重要组成部分,在国家特高压电网和西北电网规划的指导下,已经规划出了满足陕北地区用电负荷长远发展和适应西北电网"西电东送"的远景目标网架结构。阐述了陕北与关中电网的送受电关系,论述了陕北发展750 kV电网的必要性;从陕北750 kV变电站的布局、落点、主要断面输电能力等方面论证了陕北750/330 kV主网架结构的合理性。

The last three years of ＂Eleventh Five Year Plan＂ is important period for the leaping development of Northwest 750kV power grid. For Northern Shaanxi power grid is important part of Northwest power grid, under the guidance of UHV ＆ Northwest power grid planning, grid structure that meet the long-term development of electricity load in Northern Shaanxi, and adapt to long- term target of power transmission from west China to east China has been planned. The power receiving and sending relation between Northern Shaanxi and Guanzhong power grid is elaborated, the necessity to develop 750kV power grid in Northern Shaanxi is indicated. The rationality of Northern Shaanxi 750/330kV main power grid structure is demonstrated in view of arrangement, location, main section power transmission ability of 750kV substation in Northern Shaanxi.
