摘要
灭磁系统是同步发电机组励磁系统的关键装置之一,合理选取灭磁控制电压可以提高灭磁系统装置运行的可靠性,有助于提高励磁系统的稳定性。通过分析灭磁主回路,以典型机组参数为基础进行灭磁仿真,并结合现有机组的使用情况,得出了非线性灭磁电压选取的方法,为大型机组励磁系统灭磁部分的设计和器件的选择提供了依据。
The de-excitation system is one of the key devices in the excitation system. If the reasonable controlled voltage of de-excitation is selected, the reliability of de-excitation system and the stability of the excitation system will be improved. The main circuit of de-excitation is analyzed, and a de-excitation simulation based on a typical generator parameters is finished. The selection method of de-excitation voltage for nonlinear resistance is obtained. And it also provides evidence for the de-excitation design of excitation system and components selection, and has important guiding significance.
