高压GIS控制及保护装置研制

针对气体绝缘封闭组合电器(GIS)智能化的要求研制了一种基于高性能32位双CPU结构的新型装置。采用数字信号处理器(DSP)TMS320VC33和ARM嵌入式处理器AT91RM9200,双口RAM用于双处理器间的高速数据交换。DSP模块通过复杂可编程逻辑器件(CPLD)完成数据测量、命令执行和保护判断等功能;ARM模块内嵌uClinux操作系统,主要完成人机接口、事故记录、启动保护出口和通信等功能;双CPU共享电压频率转换器(VFC)采集数据。详细介绍了系统的硬件、软件设计方案和抗干扰措施,采用C语言和VerilogHDL语言开发系统软件,并提供了保护算法及各个功能模块的软件结构。实验测试和现场运行结果表明该系统可靠性高、组网能力强,满足对GIS监控和保护的要求。

Development of control and protection device for HV GIS

For the intelligent control and protection of GIS(Gas Insulated Switchgear),a device based on dual 32-bit high-performance CPU of DSP(Digital Signal Processor) TMS320VC33 and ARM(Advanced RISC Machines) embedded microprocessor AT91RM9200 is developed,in which the dual-port RAM is used to realize the high-speed data exchange between two processors.The DSP module,with the aid of CPLD(Complex Programmable Logic Device),realizes the functions of data measurement,command execution,protection judgment,and so on.The ARM module,with the embedded operating system uClinux,realizes the functions of man-machine interface,fault record,protective trip output,communication,and so on.The outputs of VFC(Voltage Frequency Converter) are shared by two CPUs.The system design,including HW and SW,and the anti-interference measures are introduced in detail.The system SW is developed with C language and Verilog HDL language.The protection algorithms and the flowcharts of function modules are provided.Experiments and field operations show its high reliability,good networking capability,meeting the requirements of GIS control and protection.
