摘要
近年来宜宾电网负荷增长较快,电网供电能力未能随负荷的增长而同步增长,电网供需矛盾比较突出。为此,针对宜宾电网现状及2008年迎峰度夏期间电网结构,按照与电网安全相关的负荷水平、断面潮流、单一元件切除后设备过载能力以及进行必要事故限电等情况进行了分析,提出解决建议。
In recent years, the load growth of Yibin Power Grid is rapid, but the power supply of the power grid is not growing with the simultaneous increase in growth of load capacity, so the power grid has more prominent contradictions between supply and demand. To this end, aiming at the status of Yibin Power Grid and its structure during the summer peaks in 2008, some conditions are analyzed, such as load levels related to power grid security, the trend of cross - section, overload capacity of equipment after the removal of a single component and the necessary emergency load shedding, and then the suggestions are proposed.
