【摘要】 采用优化方法分析了配电网可靠性与经济性之间的关系。优化的目标函数为停电损失函数,状态变量为负荷点的强迫停运率和强迫停运时间,利用非线性规划计算状态变量的优化值,作为进行配电网规划、供电设备检修的依据。结果表明,该方法有效可行,优于传统的技术经济多方案的比较方法。更多还原

【Abstract】 Overhauling devices and adopting new devices can improve the reliability of distribution networks, whereas cost price will be increased meanwhile. Optimization theory is used to evaluate reliability and cost of power supplying system in this paper, where objective function of optimization is interruption loss function, and its state variables are forced outrage rate and forced interruption duration. Optimal values of state variables are obtained by nonlinear programming. An instance indicates that optimization method of power supply system reliability is practical and superior to traditional multi-scheme comparing approach.更多还原
