| 摘 要： | 本文旨在探讨一套新的、具有较高性能价格比的微机式距离保护方案。文中提出了基于电流、电压对称分量的保护动作方程式,建立了一种新的(1.a)座标平面,并在此平面上导出了精度较高、计算量很少的对称分量滤波算法。编制的保护程序在单片机开发系统上调试通过。数字模拟试验表明,保护方案可行,性能良好。

| Abstract: | In this paper, a new microcomputer distance protection scheme with high property-cost ratio has been approached. The paper presents the performance equations based on the symmetrical components of current and voltage, proposes a new (1,a) coordinate plane and derives a Fourier symmetrical component algorithem with high accuracy and less calculation amount on the (1,a) plane. The protection program is debugged on the developing system of single chip computer. The digital imitation tests indicate that the proposed relaying system is satisfactory. |
