摘　　要：输电网运行状态是否满意,体现于输电网运行是否能够满足其利益相关者的需求;输电网运行评估指标集即评估输电网利益相关者的需求满足程度。其中,外部需求指的是输电网运行的外部利益相关者(即发电企业、配电网企业、互联输电网企业)对输电网运行的需求。深入分析了输电网运行的外部需求,将其概括为:输电网在特定的时间,向特定的节点,以特定的质量标准,提供或接纳特定数量的电能。不同类型外部节点具有不同的需求,详细研究了节点在质量和数量2个方面的具体需求,并阐述了外部需求满足程度的评估方法。针对具体的外部需求,选取了科学、合理的指标评估在单时间断面和统计周期时间内的需求满足程度,从而构建了输电网运行评估指标体系的外部需求评估指标集。The status of transmission network operaion is satified when the demand from the diverse transmission system stakeholders is satified. Therefore, the evaluation index system for transmission network operation is actually evaluating the demand satisfaction from the stakeholders in transmission system. Especially, the external demand is the demand for transmission network operation from the external stakeholders of the transmission system, including the generation enterprise, the distribution enterprise, the interconnected transmission enterprise. The external demand was analyzed and concluded as follow ： the local transmission system should accomodate power energy with specified quality and quantity from or provide it to the specified node in the specified time. Different types of external nodes had different demands, so this paper studied different quality and quantity demands of the power energy from different external nodes in detail, and expounded the evaluation methods for the satisfaction degree of the external demand. According to the specific external demand, the scientific and reasonable index was selected to evaluate the instantaneous demand satisfaction degree or in statistics cycle time, thus the external demand index set was proposed for the evaluation index system of transmission network operation.
