基于DSP+MCU的电力同步相量测量装置的设计

Design of synchronous phasor measurement unit based on DSP+MCU

针对同步相量测量需要高速采集和高速数据传输的特性,提出处理器采用双CPU结构同步相量测量装置,通过GPS授时时钟确保异地相量采集时间的同步性,然后按照模块化的设计思想对采集单元、时钟同步单元、双口RAM单元等模块进行设计,并在uC/OS-II操作系统上完成了这个功能模块优先级的分配,实验结果表明:所研制的测量装置设计合理,能够满足测量的技术指标要求,具有高精度和高速通信的特点。

Aiming at the needs of high-speed acquisition and high-speed data transmission characteristics in synchronized phasor measurement,this paper puts forward the Synchronous Phasor Measurement Unit based on double CPUs Which is M16C62P Chip and TMS320LF2407,using GPS timing to ensure that the amount of off-site phase of the synchronization acquisition time.Then,it designs the collecting unit,time synchronized unit,double RAM ect.,completes the allocation of priorities of function module in uC/OS-II operating system.After the final experimental results show that： The development of a measuring device designed to meet technical requirements measured with high precision and high-speed communications features.
