技术领域Technical Field
本发明涉及电力系统监控与维护技术领域,尤其涉及一种配电设备健康状态评估方法及系统。The present invention relates to the technical field of power system monitoring and maintenance, and in particular to a method and system for evaluating the health status of power distribution equipment.
背景技术Background Art
随着电力需求的不断增加和电网规模的日益扩大,配电设备的健康状态评估变得越来越重要。配电设备在电力系统中承担着关键的传输和分配任务,其运行状态直接关系到电力系统的安全和稳定。传统的配电设备健康状态评估方法主要依赖于定期检修和人工经验,这些方法存在效率低、准确性差、维护成本高等问题。在现代电力系统中,随着传感技术、物联网和大数据分析技术的发展,配电设备运行数据的实时监测和智能分析成为可能,为实现更加精准的健康状态评估提供了技术基础。With the continuous increase in electricity demand and the ever-expanding scale of power grids, the health status assessment of distribution equipment has become increasingly important. Distribution equipment undertakes key transmission and distribution tasks in the power system, and its operating status is directly related to the safety and stability of the power system. Traditional methods for assessing the health status of distribution equipment mainly rely on regular maintenance and manual experience, which have problems such as low efficiency, poor accuracy, and high maintenance costs. In modern power systems, with the development of sensor technology, the Internet of Things, and big data analysis technology, real-time monitoring and intelligent analysis of distribution equipment operating data have become possible, providing a technical basis for achieving more accurate health status assessment.
然而,现有技术在实际应用中仍存在诸多技术问题。首先,传统的健康状态评估方法通常依赖单一的参数(如温度或电流)进行评估,无法全面反映设备的真实运行状态。其次,即使一些先进的评估方法使用了多参数数据,但在数据融合和特征提取方面仍存在不足,导致评估结果的可靠性和准确性不高。此外,现有技术在异常预警和故障诊断方面缺乏智能化手段,无法及时、准确地识别故障类型、位置和原因,导致设备维护和管理滞后,增加了电力系统运行的风险。However, there are still many technical problems in the practical application of existing technologies. First, traditional health status assessment methods usually rely on a single parameter (such as temperature or current) for assessment, which cannot fully reflect the actual operating status of the equipment. Secondly, even if some advanced assessment methods use multi-parameter data, there are still deficiencies in data fusion and feature extraction, resulting in low reliability and accuracy of the assessment results. In addition, existing technologies lack intelligent means in abnormal warning and fault diagnosis, and cannot identify the type, location and cause of faults in a timely and accurate manner, resulting in delayed equipment maintenance and management, and increasing the risk of power system operation.
