Beijing Tianjin Hebei ship and marine engineering industry collaborativedevelopment forum held in Tianjin  

    Pan Jingfu ChineseThe forum, experts of Shanghai Waigaoqiao Shipbuilding Co. Ltd. this company is combined with the 18000TEU container ship built, introduces the equipment layout, the relevant ship intermediate voltage powersystem installation and test engineering experience. China Shipbuilding Industry Corp seventh / Four Research Institute introduced the progress and achievements have been made in research on the key technology ofthe offshore platform power station is located on the. This will be theacademic research and production practice, combining the practice ofShanghai City, this year is the ship and Marine Engineering Society held a series of technical forum a great characteristic Academy of Engineering in the report on the development of shipboard power system have been reviewed and prospected. He said, since the 80s of the last century, the rise of power electronic technology, the rapid development of the AC motor variable frequency speed regulation technology, era to DC system primarily long-term shipboard power system to the end. With the increasing of shipdisplacement, electrical equipment and electric propulsion ship power station capacity of extensive use of technology, also will rise. If the ship isshort circuit fault in operation, short circuit current will follow the "expansion". Therefore, large ships required by medium pressure systemto ensure safety. In the marine engineering ship and ocean platformequipment, as a result of special equipment more often use electric propulsion and dynamic positioning technology. Therefore, increasingpower, improve the voltage level must be. At present, domestic and external large ships and marine ship domain, power plant voltage has been increased from past low voltage 450 V MV 3000~15000 volts,current frequency from the low frequency 60 Hz promotion to theintermediate frequency of 200~400 hz. Although the United States and other countries started earlier in the techniques of marine medium voltage power system, is in the advanced position of our country in the field, but also have the most advanced technology, the two is equal. Pan Jingfu emphasizes, because the medium voltage power systemtransformer, rectifier, inverter needs through such measures to the wholeship user power supply, therefore, the development of power electronicequipment with high reliability, is the key to realize the integrated full electric propulsion technology. At the same time, monitoring, control andmanagement of the whole system, also need to automation, intelligent and networked direction to accelerate the development of.
