Intelligent operation and maintenance solution for power supply

Business Challenge

Multiple monitoring systemsThe rail transit power supply system comprises various complex components, including external transmission lines, main substations (switching stations), 35kV (10kV) medium-voltage ring networks, traction and step-down hybrid substations, step-down substations, overhead contact systems (rails), stray current protection and grounding systems, low-voltage power distribution systems, and power lighting systems.

High maintenance intensityCurrently, the main operational mode involves instrument-assisted detection and manual visual judgment, which results in high labor intensity, low operational efficiency, and difficulty in quality control.

High-risk homeworkThe high-risk work environment is accompanied by frequent high-intensity operations, making it difficult to verify the standardized execution of tasks, and the risk factor of the operations is high.

The scope of the fault impact is extensiveIn the event of a failure, it will attract high social attention, require a long period for fault handling, and cause a wide impact.

Solution Introduction The intelligent operation and maintenance solution for rail transit power supply, based on intelligent inspection robots, online sensors, auxiliary monitoring equipment, and a centralized control platform, utilizes a multi-sensor fusion approach combined with intelligent equipment integration to achieve broader coverage of power supply equipment inspection content and inspection points. At the same time, it can interface with systems such as power monitoring systems, five-prevention systems, one-click smooth control, and access control switches, enabling real-time status monitoring and data analysis of power supply stations and system equipment.

Intelligent inspection of substationBy deploying terminal acquisition devices such as robots, dual-spectrum cameras, fixed cameras, and temperature sensors, real-time monitoring of equipment status in the computer room can be achieved. By connecting these acquisition devices to the integrated power supply inspection platform, unattended or less-attended operation within the scene can be realized. At the same time, SCADA, visual grounding, and various sensors can be connected to form unified monitoring of the power supply system.

Intelligent operation of switch roomUse switchgear room operation robots to replace manual labor for routine and emergency operations. In addition, the robots possess intelligent inspection capabilities, supporting integrated inspection and operation tasks.

Rigid contact network inspectionThe portable intelligent detector for rigid contact wire wear focuses on the inspection of rigid contact wire wear and the analysis of abnormal data. It analyzes the wear characteristics and wear trends of the rigid contact wire from two aspects: wear distribution and wear morphology, meeting business needs. The detection system is also equipped with a contact wire dust removal device, which performs dust removal while detecting, ensuring more accurate detection data.

Pantograph wear detectionThe portable intelligent carbon strip wear detector is developed to meet the business needs of daily carbon strip wear inspection and abnormal wear tracking for electric multiple units (EMUs) in rail transit. It features full carbon strip detection, high detection accuracy, adaptability to the entire business process, complete data recording, and diversified output formats.

Solution Value

Assist in unmanned inspection of station buildingsThrough the deployment of various online sensors and robots, unmanned inspection of rail transit power transformation and distribution stations can be achieved, enhancing the level of intelligence.

Interconnection and interoperability of data informationThe uniformly established intelligent operation and maintenance system for power supply can achieve interconnection and interoperability with the power monitoring system and production management network, enabling unified management across the network and collaboration among multiple systems.

Operational risk continues to decreaseBy adding intelligent detection equipment, we aim to enhance the working environment for maintenance personnel and reduce the risks associated with daily operations.

Optimization of human resource inputThe launch of intelligent equipment and systems can effectively improve the efficiency-to-cost ratio of power supply operations and optimize human resource allocation.
