在众多的发电机类型中,无刷励磁发电机由于其独到的设计,而受到了广大用户的欢迎。但是,这类机组也有一个明显的缺点,即对运行中的发电机无法进行直流(励磁电流)监视。由于电网的不断变化,特别是当电力调度部门要求电站进行无功调相运行,或进行顶峰发电时,就碰到了这种(无法监视励磁电流大小的)困难。为了解决这一存在的 Among the many generator types, brushless excitation generators are welcomed by the majority of users due to their unique design. However, there is also a significant disadvantage of this type of unit, which is that it is not possible to monitor DC (field current) generators in operation. Due to the ever-changing power grids, difficulties (such as the inability to monitor the magnitude of the magnetizing current) have been encountered, especially when the power dispatching department requires that the power station be operated with reactive power and phase modulation or with peak power generation. In order to solve this existence
