The Design Of A Deep-sea ROV Power Transmission And Electricity Supply System

As the development of ocean engineering and deep-sea mining, the exploration of ocean has turned from the shallow sea to the deep sea. In the deep and dangerous regions of the deep-sea, Remote Operated Vehicle (ROV) have been playing a crucial role. Deep-sea power and electricity supply and distribution system are significant part of ROV that provides stable power to ROV. As one of the key technologies of ROV system, power and electricity supply and distribution system have aroused wide concern and been widely studied due to its direct effect on the performance of ROV in recent years.Concerned with the background of the project, the power driving and transmission system for the 4500-meter cable under-water vehicles was designed and studied in this paper. Moreover, based on these studies, the electricity supply and distribution system for ROV was also investigated and developed. The results showed that the power and electricity supply and distribution system designed in this paper satisfied the operation conditions and performance requirement of ROV.This paper was divided into five chapters:Chapter 1 presented a survey on the development state and trend of the power and electricity supply and distribution system, and introduced the usual methods of power driving and supply. With analyzing the characteristics of these power systems, we proposed the research purpose, significance and content of this paper.In Chapter 2, basing on the design principle of the power driving and transmission systems and taking advantages of successful experience of overseas, we designed the power transmission system for ROV. Moreover, the hydraulic-actuated and line-start scheme were proposed, and the key components were investigated. At the end of this chapter, the feasibility analysis of the whole power transmission system was given by simulation test.Chapter 3 aimed to develop the specific hardware part of the power control system. In this chapter, an operation interface of the upper computer over the electric power cabinet is programmed by using LAB VIEW, and an integration of the console over the power supply and distribution system is developed. The results of the experiments showed that under the recent software and hardware conditions, the mother ship can take a good power control of ROV.In Chapter 4, according to the operation condition and the performance requirement of ROV, the protection and monitoring modules were developed. Also, kinds of error phenomena were analyzed and optimized. In addition, the simulation experiments of different modules were given. The result of simulation showed that theses modules can protect ROV efficiently.A summarization of the total research works in the paper was given in Chapter 5. Moreover, an expectation of the future research work was brought forward.
