摘要
对光伏并网中的双向逆变器控制系统进行了理论探讨;利用小信号分析法得出系统电压和电网电流的数学模型,设计出使光伏并网双向逆变器稳定的控制方案和选择相应参数的方法;最后,将研制出的光伏并网双向逆变器与电力系统连网,通过实验验证了该双向逆变器系统模型的可行性,对于开发和研究光伏并网逆变器的产品具有实用价值。
A double direction inverter of grid-connected photovohaic is discussed in theory.The math model of the system voltage and power grid current is established using analytical method of small signal, a control scheme of the system steady and correspond preferences is designed.Finally, solar grid-connected photovohaic inverter with power system networking run,and the experiment shows the control system model feasibility and practicability in engineering,it has utility value for development and study of grid-connected photovohaic invert product.
