基于能量平衡的电能路由器综合控制技术
Synthetical Control Technology of Electric Energy Router Based on Energy Balance Relationship
摘要
Abstract
Electric energy router is made up of multi-stage power electronics units. According to the energy relationship of each unit, the integrated control is used to improve the transient performance of the internal DC bus voltage, thereby improving the output transient performance. The energy model of electric energy router is proposed in this paper. This model is divided into two time scales of energy branches. Different energy balance controllers are designed according to the energy relationship of different time scales for controlling the two DC bus voltages. The influence of the parameter difference of passive elements in energy real system on the control performance is analyzed. After that, the whole control diagram of the electric energy router is introduced when it is connected to the grid. The simulation results verify the effectiveness of the energy balance control, and analyze the impacts to the DC bus voltage transient performance when the two DC bus capacitances are changed. Thus, it supplies the foundation for reducing the design margin of the DC bus capacitance. The experimental results verify the correctness of the theoretical analysis and the simulation results.关键词
