概述了磁饱和式可控电抗器(MCSR)和变压器式可控电抗器(TCSR)的基本结构和工作原理,详细分析了它们的控制特性.以超高压输电线路为例,应用动态无功补偿原理,采用工程设计方法,设计了MCSR和TCSR的电压控制系统。对电抗器的仿真模型及仿真参数进行了详细说明,重点介绍了两类电抗器触发脉冲的产生过程。仿真结果表明:磁饱和式和变压器式可控电抗器的功率都能够连续平滑调节,使线路末端电压在稳态时总保持为额定电压不变。而变压器式可控电抗器的响应速度更快。
The basic structure and the principle of the magnetic saturation type controllable reactor (MCSR) and the transformer type controllable reactor (TCSR) were described. Their control characteristics were analyzed in detail. By resolving the equations of EHV ( extra high voltage ) transmission line, a control system of the line voltage with MCSR and TCSR were designed employing the dynamic reactive power compensation theory and utilizing the engineering design method. The model of the reactor and the simulation parameters were described in detail. Focusing on the two types of reactors trigger pulse generation process, the results demonstrate that the voltage-control system can rapidly regulate the output power of a CSR, and can keep the line voltage stabilization, while the response time of the TCSR is smaller than MCSR.
