誘導電動機個別駆動方式電気機関車の再粘着制御に関する実験的考察

摘要

鉄道車両用としてインバータ制御により誘導電動機を駆rn動する場合の空転再粘着制御として，一般的には，空転時rnの電動機軸速度変化率から空転を検出し，トルク指令を急rn峻に粘着力推定値以下まで絞ることにより再粘着させる制rn御方法が採用されている。%We have developed a re-adhesion control algorithm of traction inverter for individual Motor control locomotives. This paper describes improvement for wheel slip and re-adhesion control for individual axle electric locomotives. Major torque control is making feedback the difference between locomotive basic speed and individual axle speed. By combining two torque control methods, we have got the better re-adhesion characteristic as follows, a little influence of dynamic axle load transfer and a high available coefficient of adhesion more than 30%. We estimated these torque control by the test run and show the stability limit of feedback gain.
