摘要随着中国智能电网的发展,电力电子技术在电力系统中得到广泛应用。模块化多电平(MMC)拓扑是目前高压、大容量电力电子装置的主要方案之一,传统集中式控制系统框架的缺点日显。通过对EtherCAT总线技术实时性、同步性、灵活性的分析,针对模块化多电平拓扑的一种H桥级联,提出了一种基于EtherCAT技术的分布式控制系统框架。搭建了9模块H桥级联平台,通过实验证明了EtherCAT总线控制系统的优良性能。根据实践经验,概括了许多应用EtherCAT技术的关键点,该分布式控制系统构建同样适用于其他的模块化多电平电力电子装置。 With smart grid development in our country, power electronics are widely used in power systems Modular Multilevel Converter （MMC） technology is major approach in current high voltage large capacity power electronic equipment. However, traditional centralized architecture of control system needs improvement. With performance analysis of EtherCAT on realtime, synchronism and flexibility, a distributed control system architecture based on EtherCAT Bus-technology is proposed. A test platform which include nine H-bridge modular is constructed. Experiment performance demonstrates excellent distributed control system behavior. Many key technologies in EtheCAT application are summarized based on practical experiences. The proposed distributed architecture is also capable for other kinds of multi voltage level power electronic equipment.
