摘要
根据零序电流相位法故障定位的原理,利用GPS秒脉冲对提取的零序电流进行同步采样,将采集到的相位数据经无线通信模块实现信息传输。在介绍基于C8051F310单片机和SRWF–508远距离无线通信模块构成的硬件系统基础上,通过对通信协议以及软件流程的设计,实现了数据的多跳传输。最终通过中心站软件判断故障区段,从而验证相位法故障定位的可行性。
According to the principle of zero sequence current phase fault location, the article uses GPS to synchronous sampling for the zero sequence current, then it transfers the phase information that collected by the wireless communication module. On the basis of introducing the hardware system that consist of C8051 F310 MCU and SRWF-508 wireless communication module, the article realizes the multi-hop transmission of data by designing communication protocol and software process. At last, it judges the fault section by center software so that it can prove the feasibility of the phase method fault location.
