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.
