摘　　要：原有系统在接收到大量电力数据时,会出现延迟现象,无法对应传感器放电点的具体位置,为准确完成放电点定位,研究一种基于FPGA智慧变电站智能终端系统。配置FPGA智能终端框架,将FPGA应用于控制主板中,实现全方位电力设备定位;设计电力设备位置响应电路,对异常数据逐个排查,完成变电站内的实时数据管理;构建多时钟域同步定位器,使其与变电站终端数据完成同步化处理。基于FPGA扩展变电站定位能力,切换正弦和余弦函数,计算相位增量下的设备定位点;测量电力设备高度与放电距离,建立非线性方程,确定终端传感器位置,完成终端系统设计。实验结果表明:所提系统能够零误差完成放电点定位,而传统系统会随着设定距离的增加,逐渐加大定位的角度误差,说明所提系统更加有效。When the original system receives a large amount of power data,there is a delay phenomenon,which can not correspond to the specific location of the sensor discharge point.In order to accurately complete the discharge point location,this paper studies an intelligent terminal system based on FPGA for smart substations.It configures the FPGA intelligent terminal frame,applies the FPGA to the control motherboard,and realizes the omni-directional power equipment positioning.It designs the position response circuit of power equipment,checks the abnormal data one by one,and completes the real-time data management in the substation.The multi clock domain synchronous locator is constructed to synchronize with the substation terminal data.The locating capability of substation is extended based on FPGA,the sine and cosine functions are switched,and the equipment locating points under the phase increment are calculated.It measures the height and discharge distance of power equipment,establishes nonlinear equations,determines the location of terminal sensors,and completes the terminal system design.The experimental results show that this system can complete the discharge point location with zero error,while the traditional system gradually increases the angle error of location with the increase of the set distance,which shows that this system is more effective.
