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。 |

Abstract: |
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). |
