自愈是智能配电网的显著特征之一,根据配电网的监测数据对其健康状态进行实时评估,是对配电网实施状态转移以达到自愈控制的前提.在分析智能配电网特点的基础上,提出面向智能配电网的健康状态评价指标,利用熵权法建立指标权重,采用模糊数学的隶属度函数建立指标的隶属关系,将指标权重与指标隶属度相结合建立一种智能配电网健康状态的综合评价方法.验证分析表明该方法可根据智能配电网检测到的众多参数信息,对其健康状态做出实时准确的评价,可为配电网的状态转移控制提供依据.

Self-healing is one of the remarkable features of smart distribution grids. Making real-time assessment of distribution grid's health status based on monitoring data is the premise for implementing state transition of the distribution gird in order to achieve self-healing control. By analyzing the characteristics of the smart distribution grid, this paper puts forward intelligent distribution grid in terms of health status evaluation index. With the index weight and the membership degree of testing data found out by the use of entropy weight method and fuzzy mathe-matics theory, a comprehensive evaluation method for the health status of SDG is proposed. It shows that the pro-posed approach can be used to accurately evaluate the real-time state of the SDG via instance analysis according to large amounts of testing data, which may provide reference for the state transition of the distribution gird.
