Yihe conducts maintaining agent management for the contracted customers' substations through centralized monitoring, centralized patrol inspections, centralized operations, and centralized management. The operating status, signals, and operation data of the substation can be remotely transmitted to remote control center through communication equipment. Then, the platform system performs a big data analysis through expert system, to determine the operating status of the equipment, so as to discover potential hidden dangers and defects in the equipment in time, and pre-judge and give early warning for the faults.


On-line monitoring: 24-hour on-line and remote centralized monitoring on substations of all contracted customers within the service network. In case of any abnormal signals, warnings, and faults in distribution room, notify the O&M team in the service area to check and handle these problems in the room in time, so as to ensure that the distribution room can be in a safe state even in an unattended state.


Offline O&M: A 24-hour O&M team is established based on the area radius, responsible for the daily inspection and maintenance, power outage and transmission, and accident handling for the contracted customers' substations in the area. In case of any alarms and faults in the substations, the team can accept the dispatch of the remote control center, and can rush to the site within 30 minutes to perform troubleshooting and resume power transmission in time.



24-hour remote real-time monitoring and professional operation and maintenance team for emergency makes the operation and maintenance services safer and more reliable!
The operation and maintenance for the power transformation and distribution station is mobile, and the operation status is monitored at any time. The power management is more convenient and more worry-free!
