Abstract
A self-adaptive distribution transformer can automatically regulate its tap changer position rated operating capacity, online load phase rotation,and phase by phase reactive compensation according to the system voltage and loading conditions without disconnecting the load. The functional architecture of self-adaptive distribution transformer is described. The controlling principles of online load phase rotation,on-load capacity regulating,phase by phase reactive compensation,and on-load voltage regulation are analyzed.The methods to determine control setting points are proposed with simulation model. Simulation and analysis results demonstrate the obvious advantages of the proposed distribution transformer.It is suitable to be used in rural distribution network,which features seasonal load,low annual average load rate,high no-load losses,and under voltages at the end user terminals and low power factor.By using self-adaptive distribution transformers,the economic operation level of distribution area can be improved,the quality of power supply for end-users will be improved,the operation loss of power network will be reduced,the energy-saving and emission reduction at the distribution network level will be maximized.关键词
