西安市饱和负荷下的330kV电网发展研究

Study of 330 kV Power Grid with Saturation Load in Xi'an

本文结合西安市的负荷变化规律和趋势,分析了西安市未来饱和负荷值及负荷密度。根据饱和负荷预测的结果,提出西安市饱和年330 kV变电站需要变电容量、台数,并对各电压等级之间的协调配合问题进行了讨论,为西安电网未来的规划提供参考。

In this paper, the values of future saturated load and load density are analyzed considering the change and trend of the electricity consuming load in Xi'an. According to the forecasting results of saturation load, the need of electric capacity in 330 kV substation, number of units and the single equipment capacity are proposed. Meanwhile, the problem of matching and coordination regrading various voltage levels is discussed so as to provide reference for future Xi'an Power Grid planning.
