励磁功率柜均流系数计算及智能均流试验研究

摘要

Application of the intelligent load sharing technique in the excitation system is introduced .Based on the cur-rent value of the parallel bridge arms and the average current output value of the excitation power unit , the current-sha-ring coefficient is calculated.Thus, the current-sharing performance of the parallel power unit can be evaluated .It is al-so demonstrated that currently the intelligent load sharing technique is not able to completely reflect the transient process of the bridge arm current sharing .The parallel bridge arm current should be taken as the reference value for the true cur-rent sharing .%介绍了智能均流在励磁系统中的实际运用，用并联桥臂电流值比和功率柜平均电流输出作为依据，计算出均流系数，以此评判并联功率柜的均流效果，且指出，目前智能均流还没有从真正意义上反映桥臂换流的暂态过程，要得到真正意义上的均流，必须以并联桥臂电流值作为计算参考。
