基于云理论的配电自动化系统可靠性成本效益分析模型

摘要

On the basis of stating basic principles and characteristics of distribution automation system based on cable fault in-dicator,cost-benefit analysis model for distribution automation system reliability was proposed. By analyzing characteristics of distribution network in our country and combining engineering calculation method for distribution system reliability, quantitative calculation on cost and benefit of distribution automation system composed of cable fault indicator for improving system reliability was conducted. Combining cloud theory,economic evaluation on transform of distribution automation sys-tem was proceeded in order to find an entry point for ideal investment on distribution automation system. Example analysis indicated that this model was provided with better practicability and feasibility.%在阐述基于电缆故障指示器的配电自动化系统的基本原理和特点的基础上，提出配电自动化系统可靠性成本效益分析模型。通过分析我国配电网的特点，结合配电系统可靠性的工程计算方法，对通过电缆故障指示器构成的配电自动化系统在提高系统可靠性方面的成本和效益进行定量计算。结合云理论对配电自动化系统改造进行经济评估，找到实施配电自动化系统理想投资的切入点。算例分析表明该模型具有较好的实用性和可行性。
