银北地区地域狭小,高载能负荷较为集中,在经济持续复苏的大背景下,地区实时负荷达到180万千瓦,笔者所在的某某220KV变电站最大落地负荷已达到420MW,与历史同期基本持平,十几年在220KV重负荷变电站从事运行维护工作,积累了一些经验,在这里做一总结.%Northern region of Yinchuan small size, and heavy load is more concentrated. In the context of sustained economic recovery, the real load has achieved 1.8 million-kilowatt. The maximum floor load of A 220KV substation where the author works has been at 420MW, and is essentially same with the same period.
