水电站(N+M)容错系统的建模及优化设计

Modeling and Optimization Design of (N+M) Fault Tolerant System for Hydropower Station

分析了（Ｎ＋Ｍ）容错系统的经济性，提出了其经济性的优化模型，并利用图视化方法进行了求解，给出了一种简单实用的最佳备件量选取方法．其基本方法和结论对多机组电站中选取控制器备件量具有重要的指导意义．

N+M) fault tolerant system (FTS) makes full use of the hardware and software of its own, and intelligent networking is a practical way to implement it, so that it is expected to have wide application in control systems. The mathematic model of cost optimization in (N+M) FTS is put forward by analyzing its economics. A simple but practical method to choose optimal number of stand by controllers is developed by means of visualization method. The idea and results proposed in the paper will play an important role in choosing the number of stand by controllers in multi unit power plants.
