为加强重要电力用户用电安全水平，开展了基于用户责任的重要电力用户用电安全风险评估研究。分析了已投运电力用户在运行管理中的用电风险因素，按照从萌芽发展到事故的逻辑顺序将风险隐患归纳为基础配置性风险、组织制度性风险、运营执行性风险和事故控制性风险等4种风险，进而建立了基于物元可拓理论的安全评价指标体系。通过实例，验证了评价体系的科学性和合理性。通过研究，为量化评估重要电力用户的用电安全风险提供了一种新的思路和方法。%This paper puts forward the electrical safety assessment for important power users (IPUs) based on user’s responsibility, in order to strengthen their electrical safety level. Analyses are made on the risk factors existing in operation and management. According to their progressions, the risk factors are divided into 4 categories, i.e. base-configuration risk, organization-institution risk, operation-execution risk and accident-controlling risk. Moreover, this paper establishes the index system for safety assessment based on the matter-element theory. Finally, an example is given to prove the feasibility and effectiveness of the assessment index system, which provides a new method to quantitatively assess the electrical safety for IPUs.
