摘要
针对冲击性负荷造成配电网电压波动的问题,提出了一种基于晶闸管开关控制技术的电压调节装置——晶闸管高压自动调压装置(thyristor voltage regulator,TVR)。首先分析了TVR工作原理、主回路和功能,然后介绍了装置中晶闸管的控制时序,最后给出了某变电站一条10 kV线路安装TVR后的仿真结果与现场运行效果。结果表明,提出的晶闸管高压自动调压装置可在具有冲击性负荷的工况下很好地稳定电压,提高电压质量。
For voltage fluctuation problem due to impact load in the distribution network,thyristor voltage regulator(TVR)which is a voltage regulating device based on thyristor switch control technology.Firstly the working principle,the main circuit and the function of TVR is analyzed,and then the thyristor control timing is introduced.Finally,the results of the simulation and the area operation based on a 10 kV line with TVR are given.The results show that TVR can steady voltage and improve voltage quality well under the condition of impact load.
