摘要
采用电力系统电磁暂态仿真程序PSCAD/EMTDC,对含10 kV大功率电动机的配电线路运行状况进行模拟。针对电机启动时造成的低电压问题,提出更换线路截面、调整供电距离、改进无功补偿、规范启动时间等技术措施,有效减小了大功率电机启动对配电线路的影响,对类似的工作具有参考价值。
The operating performance of a 10 kV circuit with a bulk-power asynchronous motor in Foshan area in Gunagdong province is investigated in this paper using the power system electromagnetic transient simulation software-PSCAD/EMTDC. The voltage drop caused by motor starting-up is studied and technical measures such as augment of circuit section, adjustment of power supply distance, improvement of reactive power compensation and specification of starting-up time are put forward thus the adverse influence of motor starting-up is reduced. The work in this paper can provide reference for similar work.
