基于动态模拟实验分析企业供电系统的稳定性

Analysis on the Stability of Enterprise Power System Based on Dynamic Simulated Experiments

针对某公司年产60万t乙烯改扩建项目的供电系统结构,重点研究了在该供电系统结构下大功率电动机启动对系统母线电压的影响.根据电力系统理论,在试验室里仿真建立一个供电系统的动态物理模型,利用仿真实验结果来验证供电系统设计的合理性和可靠性,并通过供电系统的实际运行情况也验证了实验的正确性.

Taking the structure of power supply system for 600 KTA Ethylene Plant Revamp Project, the study is focused on how big-power motors will influence the bus voltage under such a structure of power supply system. Based on relative theories about electric power system, a dynamic physical model is built emulationally in the laboratory for this power system, It verifies the rationality and stability of the power system design by experiment results. Meanwhile it proves the correctness of the experiments as compared with the actual operating conditions of the power supply system.
