Intelligent Transformer Substation


The energy market is one of the most important industrial sectors in our daily lives. It needs constant development and innovation to make it more accessible and more effective. A substation is a place where large capacity electricity is converted to local electricity or local electricity is converted to large capacity electricity. The Industrial Internet of Things is a move toward greater connectivity and control in all aspects of industrial digitization, and the energy sector is no exception. At present, distributed substation has been widely used in the power system, but because of the wide distribution range, the cost of on-site duty arrangement is high. With deep experience in the power industry, Grand Power has launched smart substation solutions to achieve remote monitoring and management of substations.


How to ensure transformer substation system reliable and stable? How to prevent and avoid the failures? It’s critical for monitoring and management such as devices operation status of main control room, real-time status of main transformer, circuit breaker and isolating switch, fire alarm and video camera real-time monitoring in transformer substation system. Due to the unmanned transformer substation in remote and distributed environment, the wired monitoring and management is obviously not realistic.


Detect the voltage and current sensors of the entrance and outlet circuits of the main transformer, the operation status of all equipment, circuit breakers and isolation switches in the control room, fire, flooding alarm, control room camera monitoring, the collected data are transmitted back to the general command center by Hongdian X2 IoT Industrial Gateway, and at the same time monitor whether the data of multiple transformer stations are normal, there is no need to send manual on-site duty. When the power transformation problem occurs, the problem of the transformer station can be remotely checked and solved. There is also an early warning report for fires and flooding, and can be dealt with in time when the shoots appear.
