摘要
结合正弦曲线拟合算法的基本概念,在中性点非直接接地系统中,介绍正弦曲线拟合三采样值故障测距的计算方法及其应用,用三相对称短路的金属性短路、经过渡电阻短路两个拟合实例,说明其正确性,该算法具有硬件简单、测量精度高、反应速度快等特点,希望该算法在电力系统发挥作用。
Combining sine curve fitting method,the basic concept in neutral grounding system directly,sine curve fitting three sample value calculation method of fault location and its application in the three-phase symmetric,short-circuit transition,the golden attribute circuit resistance short-circuit two fitting an example to illustrate the validity of this algorithm is simple,hardware,high accuracy and quick response characteristics,and hope that this algorithm plays an important role in power system.
