| 摘 要： | 厂用电快速切换是提高负荷供电可靠性的一种重要手段.鉴于现代负荷以感应电动机为主,文中以一个典型发电厂为例,采用PSCAD/EMTDC深入分析感应电动机参数对快速切换、同期捕捉切换和残压切换的三种电源切换方式的影响.研究发现电动机惯性常数和负荷转矩负载率主要影响快速切换和同期捕捉切换;而残压切换方式主要受电动机转子电阻,励磁电抗和负荷转矩负载率的影响.该文对于研制更为有效的厂用电切换装置具有一定的参考意义.

| Abstract: | Power supply transfer technique is helpful to improve the reliability of power supplying.For induction motors are the main load in the modern factories,a typical power plant was used as an example to investigate the influence of some induction motor parameters on the high-speed,synchronization capture and residual voltage transfers with PSCAD/EMTDC simulation.It is revealed that the inertia constant and load rate of the induction motors have significant influence to the high-speed and synchronization captur... |
