Automatic Control of Operation and Maintenance of High Voltage Electrical Equipment Based on PLC and Configuration Feedback Technology
Frequent voltage fluctuations in high-voltage electrical equipment have led to the accumulation of a large amount of random redundant data in the underlying controllers of mainstream DCS such as Siemens and Hollysys.Maintenance personnel need to more closely monitor the operating status data of the equipment.At the same time,equipment failures,power grid fluctuations,and constantly changing external factors overlap,resulting in a surge in monitoring data volume,further increasing the difficulty and workload of automatic monitoring.Therefore,a high-voltage electrical equipment operation and maintenance automatic control method based on PLC and configuration feedback technology is proposed.A configuration feedback technology is designed to mine real-time operation and maintenance data of high-voltage electrical equipment during the operation and maintenance process.Combining quartile algorithm and sliding window,segment detection is carried out on the data mining results to effectively identify and eliminate abnormal data points,ensure the quality of data mining and solve the problems of traditional passive monitoring.Using traditional PIDcontrol algorithm as an auxiliary tool,a PLC electrical equipment maintenance controller is established.By adaptively approximating the ideal control voltage parameters with the actual operation and maintenance parameters,automatic control of high-voltage electrical equipment operation and maintenance can be achieved.In order to further improve control performance,an integral error algorithm is introduced to avoid overshoot problems in the controller.The experimental results show that the proposed method can accurately mine real-time voltage data in the operation and maintenance of high-voltage electrical equipment.After introducing configuration feedback technology,the fault detection efficiency has been significantly improved,not only optimizing traditional monitoring methods,but also significantly enhancing the stable operation and control capabilities of high-voltage electrical equipment,resulting in a better level of control efficacy.
