中文摘要：
为研究变压器式可控电抗器CRT（controllable reactor of transformer type）的暂态特性,将CRT的工作过程分为接入过程和换级过程,并根据等值电路图分别建立了暂态数学模型.以包含4个控制绕组的CRT为例,利用电磁暂态计算程序ATP-EMTP建立了仿真模型.通过对不同电压初相位的仿真计算,得出了最理想的接入过程工作方式,以及在最严重情况下的激磁电流;通过对不同晶闸管投入时刻下换级过程的仿真分析,得出了最理想的换级过程工作方式.仿真结果与分析结果一致,可以为CRT后续的控制系统设计提供可靠的暂态性能数据.
英文摘要：
In order to study the transient characteristics of Controllable Reactor of Transformer Type,CRT process is classified into operating process and grade-changing process,and the transient mathematical models of two processes are set up respectively according to the equivalent circuit diagram.Based on the electromagnetic transient program ATP-EMTP,a simulation model of four control-winding CRT is established.The optimal way of operating process is obtained and the value of magnetizing current in the most severe case is calculated by simulating different initial phases of the operating process.The optimal way of grade-changing process is got according to the simulation of different thyristor switch-on time of grade-changing process.The result in simulation accords with the result in analysis and it can provide reliable transient performance data to CRT at the design of control stage.
