摘要
基于不同负荷密度,建立了优化选择分区电网供电方案的数学模型。充分考虑电网实际运行中各种约束条件,以年费用最小为目标,确定关于该分区电网内220kV变电站个数、变电容量与变压器台数的最优供电方案。该方案对电网规划具有一定的参考意义和实用价值。
Optimized mathematic model of power supply scheme is built based on different load density. Various constrains of actual grid operation are taken into account. The number and capacity of 220 kV substation, as well as the number of transformer in the power grid are confirmed to minimize annual cost. The proposed scheme is meaningful for power network planning.
