Abstract

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.

高压直流输电线路整流阀侧饱和电抗器铁芯损耗的仿真研究

建立了一种基于PSCAD的高压直流输电12脉冲变换器模型，其中包含具有反向恢复特性的晶闸管模型和由非线性电阻模型和可控电流源组成的非线性饱和电抗器模型，研究了传输直流电流对饱和电抗器铁芯损耗的影响。饱和电抗器的铁芯损耗不仅在转炉阀开启时产生，而且在转炉阀关闭和关断状态时也会产生。饱和电抗器的铁芯损耗随直流电流的增大而增大。
