Abstract: Under the background of the first shipboard application of the medium voltage direct current (DC) integrated power system, the technical principles and characteristics of several high-power medium voltage DC test loads that were successfully developed in China recently are studied aiming at the mooring test load requirements of the large-capacity marine medium voltage DC power station. The performance of these test loads is then summarized and compared. Finally, suggestion of designing an energy-feedback combined load system is proposed together with the actual application conditions of the test loads in the shipyard mooring test and the development of the marine test loads. The test load function can be achieved while reasonably utilizing the energy generated during the power station test, in order to provide a preliminary scheme of the load system. It can provide theoretical references for the selection and application of the subsequent large-capacity medium voltage DC power station test load.

Key words: integrated power system, medium voltage DC power station, mooring test, test load, energy feedback

摘要： 在中压直流综合电力系统首次装船应用的背景下,文中针对船舶大容量中压直流电站的系泊试验负载需求,首先研究了近年来国内成功研制的几种大功率中压直流试验负载的技术原理及特点;然后总结和对比了这几种试验负载的使用性能;最后结合船厂码头系泊试验阶段中,试验负载的实际应用条件以及船用试验负载的发展趋势,提出设计能量回馈型组合负载系统的建议,可在实现试验负载功能的同时,合理利用试验产生的能量,并给出负载系统初步方案。该文可为后续大容量中压直流电站试验负载实船选型应用提供理论参考。
