摘要
针对备自投装置已经不能很好地保证大型企业负荷供电的连续可靠性,为了更好地满足企业生产的要求,本文提出了应用快切技术的必要性,分析了负荷电动机冲击电流产生的机理。结合天津石化供电系统利用电力系统综合分析程序(PSASP)进行实例仿真,通过对仿真结果的对比分析充分说明了快切技术在电源切换和保证供电连续可靠性方面的优越性。
Most domestic enterprises used the auto-put-in device of reserve-source. While this device has a long action time, big impulse current, and can often cause the failure of switching power supply. Considering that the auto-put-in device of reserve-source can not guarantee the continuous and reliability of the enterprise＇s load power supply, this paper proposes the necessity of using the fast cutting technology in order to better meet the production requirements. The paper also analyzes the mechanism of production of the load motor impulse current. Combining with the power supply system of Tianjin petrochemical the paper uses the PSASP simulation software to do the simulation analysis. The simulation results show fully the superiority of fast cutting technology in power switching and capability of ensuring the power supply reliability.
