| 摘要: |
| 从经济性和可靠性两方面，对包含110kV高压配电网和10kV中压配电网的城市组合电网接线模式进行了分析比较。采用了一种供电面积可调的分析模型。根据负荷密度和变电所容量大小改变供电区域半径。采用“单位负荷年费用”为经济性指标，以“平均用电有效度”为可靠性指标．对两级配电网形成的组合电网进行了经济性和可靠性指标的量化计算，研究2种指标随负荷密度和变电所容量变化的趋势，以及进行相同条件下不同接线模式之间的比较。在对计算结果综合分析的基础上，根据不同情况推荐了具有参考意义的接线模式。 |

| Abstract: |
| As viewed from economy and reliability,the connection modes of urban combination systems,which are composed of 110 kV high voltage networks and 10 kV middle voltage networks,are analyzed and compared. A power supply area,adjustable model is adopted,which adapts its sup , ply radius to the associated load density and substation capacity. The economy index of annual cost for unit load and the reliability index of ASAI are adopted and quantified for the combination power system to study their trends by the change of load density and substation capacity. Different connection modes in the same condition are compared. Based on the synthetic analysis of calcula, tive results,several connection modes are commended to different application circumstances. |
