Marine Power Station Control System Based On Plc

With the continuous development of the shipbuilding, ship power plants increasingly high degree of automation. Ship power station with a supply of multiple units in parallel, to ship power plant automation, all aspects must be an organic link up to form an overall control system, collected from all diesel engines, generators, circuit breakers, as well as necessary information and parameters of the main load, and analysis, judgment, and automatically take appropriate measures under the right conditions to deal with various situations that may arise in the power plant operation to ensure that the power system is safe, reliable and economical operation.This paper designs a set of ship power plant monitoring system based on programmable logic controllers and industrial network communications, application of advanced industrial control technology, computer technology, network technology and communication technology, improve system reliability, security and economy. This article describes the steps of using the Siemens S7-200programmable controller to combine HGM6510control module to ship power plant automation and control methods. Host computer combined with the next crew in the design of automatic control of ship power plant. The next bit machine using the programmable logic controller to achieve a specific control task, the host computer using the power control configuration software, the status display, remote control and alarm functions.Through the analysis of ship power station automatic control device as a whole and the various parts of the control strategy. Control strategy, the specific design of the control system, including automatic start, automatic car, automatic solution to the column, Automatic Frequency Modulation, and other sectors. Configuration software for the design of the PC monitoring system, power control and visualization interface designed to monitor the ship power plant control functions and operating practices. The man-machine interface design, and visualization, enabling the operator to fully grasp the operating status of the entire power plant system, which according to the power station site and make the appropriate control action.This article is based on the PLC ship power plant control system has passed the system debugging, basic real-time monitoring of ship power plant has been put into use in the Yuchai Engine Company Limited.
