EEA-22 Ship Power Control System Fault Tree Construction And Analysis

With the development of modern society, on the reliable operation of electrical automation systems put forward higher requirements. In a number of high security and reliability requirements in areas of the power equipment control things, and follow-up management becomes more and more important, for the ship power plant is no exception. Ship Power Station is the heart of the ship power system on the ship's safe navigation and economic benefits have an important impact. Ship Power Automation is the development of ship power plant is an important trend is the advanced level of ship power plant the main indicator. Power supply continuity, reliability and power quality will directly affect the ship's economic indicators, technical indicators and vitality. In order to achieve the reliability of ship power plant operation and management controls and security.The system with fault tree analysis of the failure to conduct qualitative and quantitative analysis method, known as fault tree analysis (FTA). Reliability engineering is an important branch of systems engineering, while the fault tree analysis (FTA) is the system reliability analysis of a main method, especially for large complex systems in terms of reliability. Currently FTA from the aerospace, nuclear energy into the general electronic, electrical, chemical, machinery, transportation and even areas such as civil construction, but in the domestic shipping and port the application of automation system is also low, particularly in the ship power plant management applications were still significantly lack of, which is obviously the development of ship power plant automation technology are incompatible.This article will EEA-22 ship power plant automatic control system as a relatively independent system, using fault tree analysis methods, the establishment of fault tree, and its qualitative and quantitative analysis.Automatic control system of ship power plant established fault tree can be quickly and accurately diagnose the nature of a fault location, which in time troubleshooting, and based on qualitative and quantitative fault tree analysis, the proposed equipment and system maintenance cycle recommended Spare Parts to achieve reliable marine power station control and safe operation. Marine equipment, especially of civilian vessels, priority will need to consider the economic and reliability, do not need to pursue high-tech, therefore, EEA-22 automatic control system for ship power station has been in use for many years though, but it is still a good performance by the users of all ages, in fact there are still widely used on board. Therefore, the establishment of EEA-22 ship power plant control system fault tree, and their fault diagnosis is very necessary and very topical issue.
