【摘要】 为实时监控一台20kV·A的统一潮流控制器(UPFC)物理模型试验装置,满足研究在不同控制规律下UPFC动态性能和系统响应的需要,开发研制了基于DSP的多通道高性能同步数据采集监控系统。在TI高性能浮点数数字信号处理器的支持下,该系统能够以100kHz的速率对36路模拟量、64路开关量实现并行同步采样,并支持以4MB/s的速率通过PCI接口芯片将数据传送到主机内存;同时,提供8路继电器输出和RS-232串行通信接口用于控制UPFC模型试验系统的运行。基于Labwindows/CVI开发的平台应用层监控软件实现了对UPFC模型系统运行数据的实时采集、分析处理和显示录波,并提供了控制UPFC模型装置运行方式的人机接口。现场实测表明,该平台实现了对UPFC模型装置的实时在线监控功能。更多还原

【Abstract】 A multiple-channel high-performance synchronous SCADA system based on DSP is developed to study the dynamic performances and system response of a physical test model of 20 kV·A UPFC under different control rules.With TI high-performance float-point DSP,the system implements synchronous parallel sampling of 36 analogs and 64 binaries with sampling rate at 100 kHz,and transfers data from DSP to host memory with 4 MB /s rate via PCI bus interface chip.It has 8 output relays and a RS-232 serial communication interface to control the operation of UPFC model.The application software developed with Labwindows /CVI realizes the real-time acquisition,analysis,display and archiving of UPFC model operating data,as well as the human-machine interface to control the operation of UPFC model.Field experiments have verified these functions.更多还原
