摘　　要：基于风力发电路灯的能量转化机制,该文构建并分析了具有启动时间和完全故障策略的M/M/1排队系统驱动的流体模型.首先,对驱动系统进行模型描述,运用矩阵几何解方法得到驱动系统的稳态概率分布.其次,引入流体模型的净输入率结构,并利用概率分析方法得到流体库存水平在稳态条件下的微分差分方程组,进而运用Laplace-Stieltjes transform(LST)方法得到稳态条件下库存量的均值及空库概率.根据性能指标构建系统的费用函数,在数值分析中给出系统参数对性能指标和费用的影响.Based on the energy conversion mechanism of wind power street lamps,this paper constructed and analyzed a fluid model driven by the M/M/1 queueing system with set-up time and complete failure.Firstly,the driving system is described and the stationary probability distribution of the driving system is obtained by using the matrix-geometry method.Secondly,the differential and difference equations of the fluid level in steady-state conditions are obtained based on the net input rate structure of the fluid model and using the probability analysis method.Then,the expected buffer content and the probability of the empty buffer under steady-state conditions are obtained by using the Laplace-Stieltjes transform(LST)method.The cost function of the system is constructed according to the performance index.Finally,the influence of parameters changing on the performance indicators and cost function are illustrated in numerical analysis.
