All Electric Ship - The Super Platform for Tomorrow's Naval Warfare
Traditional warship power system configuration onboard has dedicated power sources for propulsion and ship electrical power generation. Due to change in the philosophy of naval warfare, more unconventional weapon systems, weapon launchers and sensors are gaining increasing importance. In order to meet the power requirements of such new breed of systems along with electrical drives, drastic increase in electrical power requirement is envisaged in futuristic warships. This trend of increasing power demands onboard warships along with superior mission requirements like: survivability, re-configurability, efficiency, stealth, compactness, flexibility and intelligent automatic control seeks a total change in traditional ship system configuration. In order to meet the above mentioned stringent requirements of the future warships without any undue implications on space, weight and performance requirements, the concept of All Electric Ship has evolved as the best possible option. In this pa...
Modern Lines of Development of ship Electromotive Systems
ELECTRICAL AND COMPUTER SYSTEMS, 2015
A comparative analysis of the main types of modern ship power systems has been made. Presented are the basic advantages of the propulsion electric units-increase of manoeuvrability, transhipment ability, efficiency, reliability and noise reduction. The main directions of development of marine electrical power systems-the use of high-voltage electrical machines, controlled-speed drives for synchronous and asynchronous motors, and valveinductor motors with permanent magnets are determined. As the most promising, power cryogenic plants and machines with high-temperature superconductors are highlighted.
RATIONALE FOR THE NEED TO USE ADDITIONAL ENERGY SOURCES IN SHIP ELECTRIC
2020
The paper shows that the existing ship power systems operate in a dynamic mode. Loads are random. Examples of accidental loads on the ship's power system are given. It is shown that ships need to improve energy systems. An effective way to increase the efficiency of energy systems is to install an additional source of electricity. Keywords: diesel generator, energy source, load.
—Recognizing the importance of electric ships and the myriad of technical challenges they present, the University of Texas at Austin, with seed funding from the Office of Naval Research, established a virtual electrical ship research and development center. The reason for the virtual center is that the complex challenges of the future require multidisciplinary solutions. The virtual center contains staff members from Electrical Engineering, Mechanical Engineering and two research centers who work collaboratively with a number of other universities and with industry. This program has two anticipated significant outcomes. At the system level, the first anticipated outcome is to develop a comprehensive set of modeling approaches that guide the evolution of electric ship power systems. The second outcome is an approach to the replacement of the hydraulic system on current ships with electrical actuators on future ships.
