电子式互感器数字输出校验方案的研究

摘要

针对智能变电站信息数字化、功能集成化、结构紧凑化的要求,设计一种实现数据分析的电子式互感器数字输出校验方案。通过分析电子式互感器的比值误差和向量误差,运用加窗的离散傅里叶算法进行了误差数据的仿真分析,LabVIEW程序验证了该方案的可行性。%Aiming at the requirement of intelligent substation information digitalization function integration and compacted structure, this paper designed a kind of electronic transformer＇s digital output calibration plan to realize data analysis. Via analysis to ratio value error and vector error of an electronic transformer, the window-added discrete Fourier algorithm was applied to carry out simulation analysis of error data. The LABVIEW program has verified the feasibility of the plan.
