| 摘 要： | 分析了轻型高压直流输电原理并建立了系统的稳态模型,结合该模型确定了控制量与被控量的关系,设计了适用于轻型高压直流输电系统的PID(比例-积分-微分)控制器;理论分析后应用PSCAD/EMTDC对四机两区域交直流系统进行仿真分析。仿真结果表明,轻型直流输电能够提高系统的电压及功角稳定性,同时可以阻止系统换相失败,对电压可达到快速恢复的目的。

| Abstract: | The principle of high voltage direct current（HVDC） light system is analyzed and its steady-state model is established.With the model,the relationship between control volume and the amount charged are determined,and the PID controller for light DC Power Systems is designed.A model of HVDC Light with four AC lines connecting two areas has been built by using the PSCAD/EMTDC.Simulation results show that the system voltage and angle stability of the HVDC light has been improved,the system commutation failure can be prevented and rapid recovery purposes to voltage can be achieved. |
