燃气轮机控制系统故障树的自动建造

Fault Tree Automatic Construction for a Gas Turbine Control System

通过一个燃气轮机间接作用式定压差流量控制系统自动建树的实例，阐述了一种燃气轮机控制系统多态故障树的自动建造（ＭＦＴＡＣ）方法。该方法使用简单，可达到较好的建树效果。在复杂的燃气轮机控制系统建树过程中，可节约大量的人力和时间，对系统可靠性分析的应用有较大的促进作用。此种方法也可用于一般控制系统故障树的自动建造，具有通用性。

Through a specific example of automatic construction of a constant differential pressure flow rate control system of indirect action for a gas turbine this paper describes a multiple state fault tree automatic construction (MFTAC) method for a gas turbine control system. The method features simplicity of usage and a fairly good tree construction effectiveness. In the course of constructing a fault tree for a complicated gas turbine control system the proposed method can lead to significant savings in manpower and time. It plays a positive role in promoting the use of system reliability analysis. Being of a versatile nature the method may also be used for the automatic construction of fault trees for 7control systems in general.
