摘要
针对微电网中危害电能质量的电压跌落问题,为了确保敏感负荷正常工作,以电网电压作为前馈输入,反馈则以负载电压作为闭环控制,根据数学模型计算其传递函数,建立了动态电压补偿模型,并通过Matlab仿真,证明该控制策略有较好的阻尼性,稳定裕度较高,动态响应速度快,系统的抗干扰能力和稳定性强。
Among many kinds of dynamic power quality problems, the voltage drop was the one that occurred most frequently and leaded to most serious harm. In order to ensure the normal operation of sensitive loads, a composite control strategy was used as with the grid voltage feed forward input. The load voltage was the feedback. According to the mathematical model, a dynamic voltage compensation model was created. Through software Matlab simulation model, a better damping of this control strategy, a higher stability margin, and a fast dynamic response, anti-jamming capability, stability, were proved.
