摘    要:动态电压质量问题随着信息技术和自动化技术的发展越来越受到重视,动态电压调节器(DVR)是解决这一问题的主要手段。作者应用根轨迹法对动态电压调节器电压环控制策略的稳定性加以分析,给出了临界稳定状态下开环根轨迹增益的计算公式。对于这个条件稳定的控制系统利用Bode图分析其相对稳定性,并计算出不同负载下的稳定裕度。得出了DVR负载电压单环反馈系统具有一定的稳定性和较好的控制补偿效果的结论。仿真和实验结果验证了电压环控制方案的可行性和有效性。

关 键 词:配电网 动态电压调节器 控制策略 电力系统

Abstract:Along with the developments of information technique and automation technique, much attention is paid to dynamic voltage problems more and more. In this paper the dynamic voltage problem of power network is presented in brief. Dynamic Voltage Restorer (DVR) is a main effective solution to this kind of problems.Using the methods of classical control theory the voltage loop control strategy of DVR is analyzed. The conclusion is that the load voltage single loop feedback system in DVR is of certain stability and better control and compensation effects. The feasibility and validity of close loop control strategy are confirmed by the simulation and tests.
Keywords:dynamic voltage quality  dynamic voltage restorer  voltage loop control.
