DSP和MAX125在单相接地选线装置中的应用
Application of DSP and MAX125 to Single Earth Fault Selection Device
【摘要】 根据TMS320LF2407的特点,介绍了DSP在小电流接地系统单相接地选线装置中的应用。为了实现对电力系统多回线路进行同时采样,装置采用了高速多通道同时采样芯片MAX125,并介绍了它的特点与使用方法。最后,给出了单相接地选线装置中的DSP软件设计方法。
【Abstract】 Based on the characteristics of TMS320LF2407, this paper presents the application of DSP to single earth fault selection device with small current grounding system. To sample multi - line in power system simultaneously, simultaneous - sampling chip with multi - channel and high speed is adopted in this device, which shows its characteristics and using method. At last,soft design in discussed in single earth fault selection device.
