From the view of operation , three active power correction strategies in reliability worth assessment of composite power system are researched and compared by sensitivity arithmetic based on taxis indexes , and on the basis of the software platform for reliability worth assessment , the correspondent software for reliability worth assessment is perfected and exploited in this thesis 本论文从运行的角度，提出了基于排序指标的灵敏度算法对组合电力系统可靠性价值评估中的三种有功安全校正策略进行了研究和比较，并在可靠性价值评估软件平台的基础上完善和编制了相应的可靠性价值评估软件。
Reliability study in power engineering system is a relatively new sphere . it first found its application in this field in the 1960 ' s , where scientists and engineers tried to predict the reliability of the power system following several disastrous power system collapses . reliability began its rapid development since reliability evaluation of power systems , a book first published in the 1970 ' s by roy billinton 可靠性技术在电力工业和电工设备制造业的应用始于二十世纪六十年代中期，自从1970年比灵顿( roybillinton )发表第一部电力系统可靠性的专著《电力系统可靠性估计》 ( reliabilityevaluationofpowersystems )以来，可靠性技术在电力系统中发展得非常迅速，逐步形成了电力系统可靠性这门学科。
With the development of industry and agriculture . the requirement for reliable running of power equipment is more and more necessary . therefore , in the areas where high realiablility and safety are required , controlling , monitoring , and follow - up managing power equipment are more and more important , the same with ship power station . in order to realize the realible control and safe operation and maintenance of ship power station , and enhance the automation degree of un manned engine room , the thesis has designed a novel distributed ship power automation system ( network monitoring and management system ) which can increase the reliability and economic effect , using advanced industrial control technology , computer technology and network programming technology 随着工农业的发展，电力系统可靠性的要求越来越重要，因此在许多可靠性和安全性要求比较高的领域，电力设备的控制、监视和管理的重要性显得越来越突出，对于船舶电站也是如此。为了实现船舶电站可靠的运行、控制和管理，提高无人机舱的自动化程度，本论文设计了一套分布式船舶电站控制系统，用先进的工业控制技术和计算机网络编程技术提高系统的可靠性和经济性。
