电力电子分布式控制体系与系统集成

为了促进电力电子标准模块(PEBB)的通用化和标准化,阐述了一种新的具有3级控制权限的电力电子分布式控制体系.参照开放系统互连参考模型,提出了此控制体系的3层通信模型,分别是物理层、会话层和应用层.确定了这3个通信层各自的功能要求和具体实现，并分析了这个通信模型和控制体系之间的映射关系.介绍了电力电子分布式控制体系的典型拓扑,以三相电压源型逆变器为例分析了该体系的基本问题,并提出了划分控制权限和确定通信接口位置的方法.研究结果表明,所提出的控制体系概念清晰、易于实现，有利于PEBB的系统集成.

Distributed power control architecture and system integration

To promote universality and standardization of power electronic building block (PEBB),a novel distributed power electronic control architecture with three level control authorities was presented.By referring to open system interconnection model,a three-layer communication model of the control architecture consisting of physical layer,session layer and application layer was proposed,and the function requirement and realization of each layer was ascertained.The mapping relation between the communication model and the control architecture was analyzed.A typical topology was discussed for the distributed power electronic control architecture,with a three-phase voltage source inverter serving as an example to analyze its basic characteristics.An approach for partitioning control authority and selecting communication interface was presented.Research results show that the proposed control architecture is easy to comprehend and implement,and facilitate system integration of PEBB.
