摘 要: 在分析了统一潮流控制器UPFC(UnifiedPowerFlowController)工作原理的基础上,给出了UPFC物理实验装置的总体设计方案。针对实验装置的核心——控制与保护系统,提出了一种多CPU的硬件体系结构,该结构将控制与保护系统分为监测、录波和控制保护等3个单元,每个单元中的插件都是一个包含了CPU(DSP)的功能模块,执行单一的任务,各功能模块均由双口RAM交换接口进行数据交换。通过ISA总线将各功能模块连接成一个整体,整套监控系统的实时性、可靠性和开放性得到较大提高。详细介绍了各功能模块的设计方法,动模实验的结果表明了这种多CPU硬件体系结构的有效性,可供其他柔性交流输电装置的控制与保护系统设计时参考。 The overall design of an experimental UPFC(Unified Power Flow Controller) is provided based on its principle. For its core:control and protection (C & P) system,multi-CPU hardware archi- tecture is presented,which is divided into three parts:monitoring unit,recording unit and C&P unit. The function module for each unit includes a CPU(DSP) to perform unitary task. Function modules exchange data with each other via dual-port RAM. All function modules connect together with ISA bus. The design of each function module is described in detail. The dynamic simulation shows that the multi -CPU hardware structure is efficient,which can be referred in designing other C &P systems of FACTS (Flexible AC Transmission System). This project is supported by the National Basic Research Program(973)(2004CB217906).
