Abstract

Controllable Reactor of Transformer Type（CRT） is an important equipment used to ensure the safe operation of high-voltage transmission system. Current-limiting inductance is an important part of CRT. The suitable current-limiting inductance parameter is basic guarantee for safe and normal operation of CRT. In this paper

a new calculation method of current-limiting inductance parameter is proposed. Firstly

the winding current calculation model of CRT under sequential single branch operation mode is given. Then

based on the calculation formula of winding current

the calculation model of current-limiting inductance is established. Finally

a concrete example is presented to verify correctness of the accurate algorithm method for current-limiting inductance which is proposed in this paper. By comparing with the existing recursive algorithm

it is found that the calculation method of current-limiting inductance which is proposed in this paper is more accurate and reasonable on the basis of satisfying harmonic demand.
