| 摘 要： | 研究了一种应用于钢铁厂供电系统中的三相应急电源系统（EPS）。将该EPS与厂电线路连接,作为后备电源使用。当市电供给出现故障时,EPS放电直流输出经过DC升压电路和PWM逆变器后为厂电系统提供快速响应容量。数字仿真结果验证了所设计的EPS系统能有效保障钢铁厂供电系统的稳定性和可靠性。

| Abstract: | The three-phase emergency power supply system（EPS） in steel plant is studied. The EPS is connected to the plant＇s circuit as backup power. In the case of power fault of main supply, discharge the EPS as response, and the DC boost circuit was used to raise EPS＇s DC output and a PWM inverter following,to provide quick response capacity for power supply. Digital simulation results verify that the designed EPS can effectively improve the stability, reliability of the power source system of steel plant. |
