摘要
针对长春地区高压配电网存在的城网容载比偏低、部分变电站负荷较重、部分66 kV联络线所带负荷较重、转带负荷空间较小等问题,从供电能力、可靠性、经济性、灵活性等方面分析了各种配电网接线模式,按照不同类型供电区域的负荷重要程度、政治经济地位、负荷密度以及负荷的发展预测,将长春地区供电规划区域划分为A、B、C、D 4类,提出了3种典型接线方式。
Aiming at the problems of low capacity-load ratio,heavy load in some substations and 66 kV tie lines,narrow forwarded load,different connection modes of distribution networks have been analysed in the fields of power supply ability,reliability,economic and flexibility.The power supply area in Changchun has been classified in A、B、C、D four levels according to load importance,political-economic status,load density and forecasting.Three typical connection modes have been proposed.
