Transformer Monitoring And Control

Energy network control
Modern energy networks are huge. Increasing power demands and supplier customer requirements have made monitoring the efficient, effective, and stable operation of suppliers a priority. Transformers are located far apart from each other. Using line techniques in this case is costly and impractical. To ensure effective wireless monitoring based on the latest technology, our company offers transformer monitoring and control systems using the NPE 9201-GPRS industrial computer. Measurement and analysis
The system consists of two parts. Control station with a central computer and external elements. Reading is done in the latter. The sensor measures the selected value and sends the result to her NPE 9201 GPRS computer. Perform the initial processing of this data. It also has the ability to react and take steps to restore stability in the event of an emergency or a loss of connectivity. Data from the NPE is sent to the control station via the GSM network. There, they are processed, analyzed, and displayed. Diagnosis is performed if there is a problem. Policy messages can be sent through the same channel.

monitoring station
A key element of such a system is a monitoring station that houses a management computer with SCADA software. Used to analyze and display received data. NPE is also there. A built-in GPRS module allows communication with transformers. The monitored object also requires his GPRS modem and microprocessor controller. This is an integral part of NPE. No additional devices are required. You can save the information for further analysis later. The format of the presentation will vary depending on your wishes. communication
The TCP/IP protocol used on the Internet is used for communication. This is a general-purpose solution that allows information to be sent to subsequent computers. Data transmission occurs in real time. GSM networks allow this solution to be used virtually anywhere. It also guarantees transmission stability.

Measurement parameters and data transmission
The outdoor module measures parameters such as temperature, load, oil flow rate, oil level in the condenser, and tap changer position. The choice of measurement variables depends on the customer's decision. The sensor communicates with the NPE using the standard RS232 protocol. Thanks to the analog output, the industrial computer can independently adjust the operating parameters of the transformer and intervene in case of problems.

remote command
Thanks to the control station computer, commands can be given remotely. GSM technology allows the transformer to send messages via SMS directly to a predefined group of mobile phones. A RS232 WiFi converter can also be used to send messages. In this way, commands can be given to the system that controls the transformer.
