Control System for Semiconductor Voltage Regulators of an On-Load Power Transformer

The features of the control system of new electronic on-load tap changer (EOLTC), for substations of distribution networks, are presented. The issues of construction of previously undescribed control systems of the EOLTC are considered. The concept of a distributed management system of the EOLTC is presented. Structural schemes for the construction of control systems of the EOLTC are proposed, their various concepts are considered and an analysis is carried out. Algorithms of interaction of control system blocks have been developed. The developed distributed control system of EOLTC is presented and its experimental study is given.
