摘要:
对市域轨道交通开通初期两座牵引变电所的负荷进行了现场测试，分析了负载率低对牵引变电所经济运行的影响。对负载率过低的牵引变电所设置无功补偿装置，根据牵引供电仿真或实测数据，并分析牵引变电所平均无功功率后确定牵引变压器的容量。准确预测轨道交通开通初期的运量，合理确定牵引变压器安装容量，按最大需量法缴纳固定电费可大大降低运营成本。
Abstracts:
Through field test of load of two traction substations in the initial stage of suburban rail transit, the impact of low load rate on the economic operation of traction substations is analyzed. Reactive power compensation device is set for traction substation with low load rate, and the capacity can be determined after analyzing the average reactive power value of traction substation according to traction power supply simulation or measured data. Accurately predicting the traffic volume at the initial stage of rail transit, reasonably determining the installation capacity of traction transformer, and paying fixed electricity charge according to the maximum demand method can greatly reduce the operation cost.
