首先采用用户问卷调查方法作为电力系统用户的缺电损失的方法,通过对缺电成本的影响因素进行仔细的分析,综合考虑影响缺电成本的多种因素的基础上设计调查问卷的,以前用户缺电成本调查表进行改进,克服了以前综合用户缺电损失函数仅依赖于缺电持续时间的片面性的缺陷;同时本文试图尝试把间接缺电成本考虑到缺电成本的模型中,使得该模型所求的缺电成本更加符合对电力系统故障的经济性评价,能真实地反应电力系统缺电损失评价的实际情况,是缺电损失评价的一种较理想的方法,具有较强的工程实用性。
In this paper, the user questionnaire is used as the user's power outage cost method, which not only improves the user questionnaire, but also overcomes the deficiency that Composite Customer Damage Function only depends on the power outage time. The power outage cost model is established, which can more truly reflect the actual situation of power outage cost in the loss assessment by taking into account the indirect power outage cost. Using customers' data in some area, the result indicates the estimation and evaluation model can estimate power outage cost under different reliabilities with a strong engineering practicality.
