摘要
探讨了在两个不同电压等级的电网引接工作电源和备用电源的问题。采取Matlab仿真系统和厂用快切原理,建立仿真模型,在工作电源与备用电源之间的相位差(俗称功角)较大的情况下,试验厂用电源之间的切换。经分析,由于快速切换和同期捕捉切换的有机结合,在厂用电源引接中,快速切换装置均能圆满完成厂用电源之间的切换,相位差不再是一个决定性的因素。
This paper discusses operating source and reserve source used by two different voltage-grade networks. It employs MATLAB simulation system and plant source fast switch theory to establish simulation model and switch plant sources when there is a large phase difference between operating source and reserve source. With the combination of fast switch and synchronous capture switch, fast switch device can implement the plant source switch in power source connecting. Phase difference is not a decisive factor.
