| 摘 要： | 高压永磁自起动同步电动机从起动到牵入同步过程是一个复杂的机电瞬变过程.在电动机设计过程中,如何使电动机的起动性能、牵入性能以及稳态运行的过载性能达到协调统一是个不容忽视的问题.基于永磁电动机转子结构的改进,本文对高压永磁同步电动机的起动过程进行了数字仿真,研究了动态起动过程,研究了直轴同步电抗、交轴同步电抗以及两种同步电抗的比值对起动转矩、牵入转矩以及失步转矩的影响,并在分析过程中结合所得结论对一台315kW、6kV高压永磁自起动同步电动机及其改进结构进行了研究论证.仿真及试验结果表明,转子结构改进后的高压永磁同步电动机在起动过程中的几种性能上各有所长,互有得失,所得这些结论对推动高压永磁自起动同步电动机的实际运用具有指导意义.
