Achieving digital controller with open architecture addressing capability and obsolescence for marine power plant

The traditional marine gas turbine control system usually used hydraulic and electrical control, which could achieve the three main functions of monitoring, control and protection. With the control requirements of the marine gas turbine continuously improved, the use of distributed digital control system was an important development direction. The digital controller was a core part of distributed digital control system. Currently, there was a plethora of low-cost commercial off-the-shelf hardware available for implementing digital controller, such as PowerPC, PLCs and PC-based boards, SoC, ASICS and so on. When considering the construction of complex distributed systems for marine power plant, the ability to rapidly integrate a variety of devices from different manufacturers is essential. In this paper, based on an open architecture, a digital controller was designed in order to verify the gas turbine distributed control system. The gas turbine distributed digital control LAN semi-physical simulation platform which includes multi-smart devices has been established and a distributed system demonstrator that has been developed to explore future distributed control systems.
