Description
Technical Field
The invention relates to a transformer, in particular to a voltage stabilizing transformer based on a self-adaptive on-load tap-changer.
Background
The voltage of the transformer can be changed due to the change of load during the operation, and the solution is that the tapping switch arranged on the high-voltage winding is used for converting the tapping of the transformer, thereby regulating the output voltage of the transformer. At present, with the access of renewable energy sources and the continuous increase of large-scale loads such as high-speed rails, subways and the like, the problem of voltage fluctuation is one of the main power quality problems faced by power grids. The voltage stabilizing transformer is a main device for solving the problem of voltage out-of-limit caused by active power transmission, and needs to have the characteristic of automatically adapting to stable voltage.
Currently, voltage regulation of a transformer generally adopts two main modes, namely on-load voltage regulation by a conversion tap and voltage regulation by a power electronic device. The tap changing on-load tap regulation regulates voltage by regulating a voltage tap of a transformer, and the tap action regulates the transformation ratio of a winding of the on-load tap changing transformer so as to maintain the voltage of a monitoring point within a specified range. The voltage regulation of the power electronic device is performed by controlling the on-off angle through the AC-DC-AC conversion of the power electronic transformer, and the split-phase voltage regulation can be performed. In addition, there are currently a few devices that utilize power electronics to switch taps.
