Description

technical field [0001] The invention relates to the technical field of the excitation power supply of the camera, in particular to a excitation power supply device of a superconducting synchronous camera. Background technique [0002] In the current field of grid reactive power compensation devices, static reactive power compensators and static synchronous compensators are mainly used, while the new generation of large-capacity compensators that have appeared in recent years have more obvious performance advantages than the former two. . After the emergence of a new generation of large-capacity tuners, other categories such as superconducting synchronous tuners also appeared. Before this, the excitation power of the synchronous motor was often powered by a single power supply, which also determined that if the excitation system was required to provide a higher multiple of strong excitation, when the power supply was in the rated state, the control angle of the thyristor rec...
