自并激励磁系统的应用

The Application of Self-Paralleling Excitation System

自并激励磁系统与其他的励磁系统相比较,具有接线简单、设备少、造价低、无转动部件、维护简单且响应速度快等明显的优势,在水电和火电机组中都得到了广泛的应用。结合自并激励磁系统的特点和原理,从自并激励磁系统的接线方式、起励方式、对继电保护装置的影响、对系统稳定的影响等方面进行了分析。

Compared with other excitation systems, the self-paralleling excitation system has the obvious advantages of simple wiring and structure, less equipment, low cost , no ro-tating components, easy maintenance and quick response, so it has been widely used in both hydro and thermal power generating units. Based on the principle and characteristics of self-paralleling excitation system, its wiring mode, excitation-starting mode, effect on the relay protection devices and effect on the stability of power system are analyzed.
