摘要: |
设备状态监测及评估是状态检修的基础,针对智能变电站技术特点,对二次设备状态监测及评估技术进行了研究。用IEC 61850采集交换机的状态信息,选取交换机端口流量、端口接收光强、发送光强、工作温度及端口误码率作为交换机的评价指标,用模糊综合评价方法,对交换机的状态进行综合评价。为防止保护出口跳闸回路触点粘连、失效、忘投压板等问题,设计后台监控系统与智能组件配合,实现了跳闸触点的定检。对间隔层、过程层之间的SV、GOOSE收发异常,提出了一种不依赖网络报文分析仪的诊断方法,诊断出是间隔层装置、还是智能组件故障。 |

Abstract: |
The equipment’s state monitoring and evaluation is the foundation of state maintenance. According to the technical features of smart substation, this paper researches on secondary equipments’ state monitoring and evaluation in smart substation. Switch state information is acquired with IEC61850, the switch port traffic, port to receiving light intensity, port to sending light intensity, working temperature and port error rate are selected as evaluation indicator of switch, and the switch state is evaluated comprehensively with the fuzzy comprehensive evaluation method. For the problem of preventing the protection of export trip circuit contact adhesion, failure, and forgetting the cast plate, the background monitoring system is designed in conjunction with the intelligent component to realize the inspection trip contact. For SV, GOOSE transceiver anomaly between the bay layer and process layer, it presents a dependency network packet analyzer diagnostic method to diagnose out a bay layer device or intelligent component failure. |
