摘要
在计算短路电流的等值电压源法中 ,对引入电压因数 C的必要性进行了深入论述 ,研究了短路电流误差ΔI″k 与电压降 ΔU关系的模型 ,以及 ΔI″k 随不同参数变化的曲线 ,提出电压因数 C的数值应取决于系统电压变化的允许范围大小 ,并给出了适合我国实际的电压因数 C的具体数值。
It is discussed that the necessity of leading in voltage factor C in calculating short circuit current with equivalent voltage source method.It is researched the relation between short circuit current error and the value of voltage drop.It is submitted that the value of voltage factor C depends on allowable variation range of power system voltage and given that the concrete value of voltage factor C suitable for our country.
