Abstract: Because of high penetration level of Distributed Generations (DGs) and rapid growth of Electric Vehicles (EVs) loads, distribution network voltage fluctuation problem becomes more and more prominent. Voltage control of distribution network is of great significance to stabilize voltage and raise voltage passing rate. The on-load tap-changing of distribution transformer is one of the means to realize voltage control of distribution network. On-load tap-changing switch is key component of distribution transformer to achieve voltage regulation. Safe and reliable operation of on-load tap-changing distribution transformer is directly influenced by its technical performance. The on-load tap-changing schemes with free maintenance or no arc and no impact switch have been put forward, but their advantages and disadvantages have not been systematic analyzed. In this paper, application situation of voltage regulation technology at home and abroad is explored. The implementation methods of distribution transformer on-load tap-changing switch technology are described and divided into three categories: mechanical, power electronics and composite. Technical implementation principle and advantages and disadvantages of different on-load tap-changing models are analyzed. Development direction and further study focus of distribution transformer on-load tap-changing technology are also clarified.

Key words: distribution network, distributed generation, voltage control, distribution transformer, on-load tap-changing technology
