5 00千伏厂口变位于昆明市西山区北部,现主要对昆明市部分城区、富民县、禄劝县及楚雄州武定县用电客户进行供电,其供电范围内的220千伏变电站有220千伏普吉变、东郊变、上峰变、狮山变、中屏变、新村变、郭家凹变、嵩明变以及金刀营变。2010年厂口变最大下网负荷达到831.7兆瓦,容载比为1 8;201 1年最大下网负荷达到1 1 36.2兆瓦,容载比为1.32。目前,500千伏厂口变在系统中的地位较为重要,一是厂口变是云电外送通道上的重要节点,500千伏潮流交换大。二是厂口变的220千伏出线达1 1回,昆明北部片区的220千伏电网全部依托500千伏厂口变供
The 500 kV substation is located in the northern part of Xishan District of Kunming City and is mainly used to supply power to some urban areas in Kunming, Fumin County, Luquan County and Wuding County in Chuxiong Prefecture. The 220 kV substations within its power supply range are 220 KV Phuket change, the eastern suburbs change, the peak change, Shishan change, change in the screen, the new village change, Guo concave change, Song Ming change and Jin Dao camp. In 2010, the maximum load on the substation reached 831.7 MW and the capacity-load ratio was 18; the maximum load on the grid reached 1 1 36.2 MW in 2011 and the capacity-to-load ratio was 1.32. At present, the status of 500kV factory outlet is more important in the system. First, factory outlet is an important node on the outgoing electricity supply channel of the cloud. The 500kV power flow exchange is large. Second, the factory outlet of 220 kV outlet up to 1 1 back, Kunming in the northern region of 220 kV power grid all relying on 500 kV factory supply
