摘　　要：随着现代工业的发展,同步电机由于其过载能力好、效率高,而且可以改善电网的功率因数,在大功率工业场所的应用越来越广泛。在阐明同步电机变频软起动的基本原理的基础上,详细介绍了其在变频软起动结束时,由变频器向电网切换的并网过程。With the development of modem industry, synchronous motor has been widely used in high-power industrial sites because of its strong overload ability, high efficiency and power factor. The process of switching from the frequency conventer to the power grid was introduced in detail at the end of the frequency conversion soft starter based on clarifying the basic principle of variable frequency soft starter in synchronous motor.
