摘要
采用能量法计算短路阻抗并结合最小作用量原理推导了短路绕组中电流分配的计算公式,导出了三个绕组分别励磁情况下的联合运行短路阻抗的表达式,并通过实例验证了公式与方法的有效性。
The short circuit impedance is calculated by energy method, and the formula of current distribution in short circuit winding is derived in combination with the principle of minimum action. The expression of the short-circuit impedance for the combined operation of three windings with separate excitation is derived. The validity of the formula and method is verified by an example.
