摘要(Abstract):

针对宝钢现有的制氧设备用空压机同步电动机在瞬时低电压情况下脱网的问题 ,利用电力系统机—网相互作用、数字仿真及电动机轴系疲劳寿命评估程序 ,研究了大型空压机用同步电机的逆功率保护延时问题 ,从而为在设备安全和简化经济运行之间寻求最佳逆功率保护整定方案提供了决策依据。
Disengaging at instantaneous low voltage of synchronous motor of oxygen producing equipment used in Bao Steel is studied by taking advantages of computer net interactive dynamic emulation of power system and fatigue life assessment process for motor shafting. A reasonable decision making method for finding an optimal scheme of reversal power protection safely and economically is provided.
