Synthetically Protective Experimental Device For Shipping Generators

The STCW78/95 convention stipulates that seaman must be given necessary training. In order for putting this convention into practice so as for a close cooperation with the phase II construction of the marine engineering laboratory that is a component of the 211 project of our school, we have developed the synthetic protection experimented device for shipping generators.The paper provides an introduction to the shipping power system; brietly describes the possible failures and abnormalties during operation of the shipping generators and the corresponsive measures against them. Besides, it also gives explanations of the significance and necesity for developing this experimental device. The synthetic protection experimental device for shipping generators is mainly composed of the shipping generator control panel, the relay protection unit, the power grid parameters for voltage and current, the A/D conversion unit, frequency and power factor angle measure unit, switch value input and output unit, central processing unit, communication voltage level change unit, PC control unit and keyboard show unit. The paper provides a comprehensive exposition on the make-up and relative hardware and software designs of the synthetic protection experimental device for shipping generators.The experimntal device can realize functions such as operation training, failure setting and system monitoring, simulate all possible questions or failures that may occur during the operation of the shipping generators under normal and abnormal working condictions. So it can achieve the goal and satisfying the demand for training and teaching seamen and university students.
