                      1 、电力电子技术在发电系统中的应用

                      1.1、 大型发电机的静止励磁控制

                      静止励磁与其他类型的励磁相比,具有实际构建成本低、结构构造形式简单、运行平稳等特点,并通过与晶闸管整流自并励的方式相结合,是当前我国最为主要、最为常见的大型发电机控制方式。近几年,我国的电力电子技术在电力传输过程中的发电环节的应用广泛,尤其是静止励磁控制,常见于大型发电机运行过程中。大型发电机在发电的过程中,一般采用静止励磁控制的控制方法促进发电机平稳地发电,同时还提高了大型发电机的运行效率。而且在实际的发电机运行过程中,大型发电机凭借先进的电力电子技术,促使晶闸管的并励和整流过程得到全面的控制,使得励磁机不再是发电系统中的必要部件,电力电子技术真正实现了大型发电机中对于静止励磁的严格控制[1]。
