| 摘 要： | 在分析地铁供电系统基本特征的基础上,建立了系统平均功率因数的数学模型,并以广州地铁2号线的运营数据为例验证了模型的有效性。对于地铁供电系统而言,高压交流电缆(33/110 kV)充电功率的影响不容忽视。结合广州地铁5号线供电系统初步设计,分析了用电负荷的波动和动力照明负荷功率因数的变化对系统110kV侧功率因数的影响,估计了动力照明负荷的临界功率因数,经过技术经济比较提出了优化的无功补偿方案。

| Abstract: | Based on the analysis of the basic characteristics of the metro power system,the computational model of the average power factor was presented.The validity of this model was verified by the operating data of the Guangzhou Metro Line 2.The influences of the charge power of the high voltage AC cables(33 kV/110 kV) on the average power factor in the metro power system should not be ignored.As far as the Guangzhou Metro Line 5 Power System was concerned,the influences of the fluctuation of the electric power load and its power factor of the low voltage side on the average power factor of the high voltage side(110 kV) were analyzed,the critical power factor of the low voltage load was computed,and an better solution of reactive power compensation was presented. |
