摘要:
针对变压器和断路器运维存在的过度依赖人工前往变电站现场的低效问题，介绍了故障录波器在变电站一次设备就地监视的特殊优势，阐述了通过录波数据提取变压器和断路器状态参数的技术原理。提出了基于调度数据网对变压器和断路器设备信息进行远程在线监视、采集、评估和发布一体化集成平台的设计方案，实现了面向运维策略的广域监视、信息分拣、特征识别、故障研判及状态评估等功能，引入了具备自学习能力的规则特征库长效机制，保证系统决策的科学性和适用性。在广州供电局的运行效果验证了系统对设备故障研判的时效性和潜在缺陷预测的准确性，增强了变压器和断路器的状态评估能力，提高了设备运行维护水平。 Abstract:Aiming at the over-reliance on the inefficient operation of transformers and circuit breakers in the field of substation, introduced the special advantages of fault wave recorder on-site monitoring of substation primary equipment, and expounded the technical principle of extracting transformer and circuit breaker state parameters by wave recording data. This paper presented a design scheme of remote on-line monitoring, acquisition, evaluation and distribution of integrated platform for transformer and circuit breaker equipment based on dispatching data network, and realized the wide area monitoring, information sorting, feature recognition, fault research and status evaluation, and introduced the long-term mechanism of regular feature library with self-learning ability to ensure the scientific and applicability of system decision-making. The operation effect of Guangzhou Power Supply Bureau has verified the accuracy of system failure judgment and potential defect prediction, and enhanced the state evaluation ability of transformer and circuit breaker, and raised the level of operation and maintenance of high equipment.
