摘要
根据微电源功率传输特性,分析了下垂控制的原理,研究了电压、电流双环控制,基于下垂控制原理在Matlab/Simulink中搭建仿真模型,将理论与实践相结合。微电网在孤岛模式下运行,当负荷扰动时,仿真结果直观地体现了下垂控制方法能够调节系统频率以及微电源输出电压的幅值,有效地解决了孤岛运行模式下微电网频率和电压幅值的支撑问题。运用于课堂教学中,有利于学生的理解和掌握。
According to the power transmission characteristics of micro power supply,the principle of droop control is analyzed. The voltage and current double loop control are studied. Based on the droop control principle,the simulation model is built in Matlab/Simulink,and the theory and practice are combined. The microgrid operates in island mode.When the load is disturbed,the simulation results intuitively show that the droop control method can adjust the system frequency and the amplitude of the micro power supply output voltage. The paper effectively solves the support problem of microgrid frequency and voltage amplitude under the island operation mode,which can be used in classroom teaching,and be conducive to students’ understanding and mastery.
