摘要
以某企业6 kV母线负荷为研究对象,利用PSCAD/EMTDC仿真软件,分析了感应电机负荷参数对快切装置动作时间的影响。研究发现,转子电阻、定子电抗、转子电抗、惯性常数、负载率对快速切换方式有很大影响;惯性常数、负载率对检同期切换方式有较大影响;转子电阻、励磁电抗、惯性常数、负载率对残压切换有较大影响。企业在对快切装置进行参数配置时需要充分考虑负荷参数的影响。
Taking the load of 6kV bus of an enterprise as the subject investigated, by use of PSCAD/ EMTDC simulation software to analyze the impact of load parameters of induction motor on the operating time of power quick.witching device. The research shows that rotor resistance, stator reactance, rotor reactance, inertia time constant and load rate has a great impact on the quick switching manner, the inertia time constant and the load rate has a great impact on simuhaneous monitoring switching manner, and the rotor resistance. magnetizing reactance, tile inertia time constant and the load rate has a great impact on residual voltage switch switching mannm＇. The impact of the load parameters should be fully considered when configuring the parameters of the power quick-switching device.
