Ship High-voltage Station Power Management System Design And Management

As the revival of shipping industry, ships tend to become much larger, more integrated and automatic, which means the capacity of ship power station need to become much larger. Up to now, the capacity of some ship power stations has been up to dozen even dozens of megawatts. If we still stick to low-voltage power station for power supply, it will be hard to realize technically and unacceptable in consideration of economic benefits. As a result, the technology of high-voltage power station is applied to ship building increasingly. As the core of high-voltage ship power station management system, power-management system's performance is directly related to the stability of high-voltage marine power station.In this paper, through the study of the composition and function of high-voltage ship power station, design the high-voltage ship power station management system. According to the character of high-voltage power station, devise an exceptional structure of power management system, and select the main hardware for some units of power management system, including the main control unit and the signal-acquisition unit. Design a multiple electronic speed and voltage regulator, this regulator controls the voltage and speed of generator in the same time. Validate the control characteristic of the regulator by simulation. In addition, design the PLC program of the main control unit of power management system, including power-supply management, load management, supervisory management and so on. The purpose of all the design is to improve the security, reliability and stability of high-voltage ship power station.In the end, according to the character of high-voltage ship power station and the working experience on board of mine, bring out some methods of high-voltage power station management, in order to make the operator more aware of high-voltage power station and how to manage and run high-voltage power station.
