发电厂警报系统的特点是其逻辑线路中包含了延时元件 ,从而引入了时间因素 ,要对这样的系统进行故障诊断 ,必须计及警报信息的时间特性。提出了发电厂警报系统故障诊断的一种新方法 ,以发展的计及警报信息时间特性的故障诊断模型为基础 ,首先将此问题描述为一个 0— 1整数规划问题 ,然后用 Tabu搜索 ( TS)方法求解。多个算例的计算结果表明了该方法的可行性。 Power plant alarm system is characterized by its logic circuit includes delay elements, which introduced the time factor, to the fault diagnosis of such systems must take into account the time characteristics of alarm information. A new method for fault diagnosis of power plant alarm system is proposed. Based on the developed fault diagnosis model which takes into account the time characteristics of alarm information, this problem is first described as a 0-1 integer programming problem, and then Tabu Search (TS ) Method to solve. The calculation results of several examples show the feasibility of the method.
