Application of the model, the voltage-current curves and power-current curves and voltage transient characteristics are gained. 应用该模型,得到了电压-电流曲线图和功率-电流曲线图,以及电压暂态特性。
Aiming at transient variations of voltage magnitude, which is one of the power quality issues, the background and actuality in the area are introduced. Then in this paper, a transformer-less series voltage transient variation compensator topology without energy storage capacitors is analyzed. 针对电能质量中电压暂变问题,本文在介绍了其控制技术的发展现状的基础上,研究了一种无变压器无储能电容的串联型电压暂变补偿电路新拓扑。
First the various causes of surge are discussed. Then the PSCAD / EMTDC software package is used for the simulation of the voltage transient processes with different disturbances. 首先讨论了电压瞬时脉冲扰动产生的原因,用PSCAD/EMTDC软件包实现电压瞬时脉冲扰动的暂态仿真。
