摘　　要：超长距离是指数千千米至6 000 km输电距离。就超长距离输电线路末端开路,3 000 km(50周波/s,半波长)输电线路输送自然功率、半自然功率和1.5倍自然功率,以及频率微小变化时输电线运行等情况,在RTDS上进行了初步数字实验研究,并归纳了验证结果,进行了初步分析,目的在于使这一实验结果为大家共享,不涉及3 000 km输电线实现的有关问题。The ultra-long span means thousand kilometers and even six thousand kilometers transmission distance.ln this paper, a preliminary experimental study is made of some cases in the RTDS. they are open-end in ultra-long transmission lines,3 000 kilometers transmission lines （50 cycles per sec, half-wave length）are transmitted natural power, semi-natural power and 1.5 times natural power, and small changes in frequency when the power is running and so on. At the last, the validation results and preliminary analysis are summarized. The purpose of this paper is to share the results of the experiment, but the relevant issues how to achieve for 3 000 kilometers transmission lines are not involved.
