Simulation Study on Iron-Core Loss of Saturable Reactor at Rectifier Valve Side in HVDC Transmission Line
A PSCAD based 12-pulse converter model for HVDC power transmission, in which the thyristor model with reverse recovery characteristics and the model of nonlinear saturable reactor composed of nonlinear resistance model and controlled current source are contained, is built to research the influences of the transmitted DC current on the iron-core loss of the saturable reactor. Taking the A5000 converter valve used in the rectifier side of ±800 kV/4 750 A UHVDC transmission project from Jinping to Sunan as the example, the iron-core losses of the saturable reactor under three different operation conditions of the UHVDC transmission line are simulated, and the simulation results conform to the on-side measured data. The iron-core loss of the saturable reactor not only comes into being while the converter valve is switching on, but also during the switching off and the off-state of the converter valve. The iron-core loss of the saturable reactor increases with the rise of the DC current.
期刊介绍：
"Power System Technology" (monthly) was founded in 1957. It is a comprehensive academic journal in the field of energy and power, supervised and sponsored by the State Grid Corporation of China. It is published by the Power System Technology Magazine Co., Ltd. of the China Electric Power Research Institute. It is publicly distributed at home and abroad and is included in 12 famous domestic and foreign literature databases such as the Engineering Index (EI) and the National Chinese Core Journals.
The purpose of "Power System Technology" is to serve the national innovation-driven development strategy, promote scientific and technological progress in my country's energy and power fields, and promote the application of new technologies and new products. "Power System Technology" has adhered to the publishing characteristics of combining "theoretical innovation with applied practice" for many years, and the scope of manuscript selection covers the fields of power generation, transmission, distribution, and electricity consumption.
