Description

technical field [0001] The present application relates to the technical field of synchronous condenser simulation, in particular to a control system of a miniature analog synchronous condenser and its working method. Background technique [0002] The synchronous condenser is also called the synchronous compensation machine. It operates in the state of the motor, without mechanical load and without prime mover drive. It can be regarded as only absorbing a small amount of active power from the power system to maintain operation, and according to the needs of the system, to the A synchronous motor that supplies or absorbs reactive power in a power system. Synchronous condensers are widely used in power system operation and control due to their smooth adjustment process, no reduction in system inertia, flexible over-excitation / under-excitation switching, large reactive power compensation power, and mature production and maintenance technologies. Therefore, the development prosp...
