Power Dispatching

Overview

The dispatching center and each sub plant station use the data dedicated line service provided by the communication operator to access the communication transmission network through leased optical channel, and build VPN on this basis to establish the power dispatching data network. The SCADA server of the dispatching center and the communication integration server of each substation are a node in the network, and are connected according to "point to multipoint" to realize dispatching communication through VPN.

Challenge

The customer looks for more stable 3G / 4G Cellular Solution to install in the Electrical panels to connect to the RTUs / Controllers to transfer the data from RTU to Dispatching Center and support implementing Modbus, DNP3 and IPSEC functionality.

Key needs for Power Dispatching:

• Robust Design: Work stable in harsh environment with strong humidity, high / low working temperature range. 

• More Function: Modbus, DNP3, IPSEC, Port Mapping

• Better Service: Provide reliable and secure data transmission in order to be monitor remote RTU / Controller in real time. 

Solution

Through serial communication ports RS232, NR300 can read all the information related to the RTU / Controllerthrough the relevant software like Modbus, DNP3 protocols and then transfer to the data center of the electricity management company. Therefore, in centers such as power transmission centers and post stations can be widely used.

Solution Advantage

- Saving Costs

NavigateWorx's NR300 helps engineers monitor real-time operation of the machines, response to faults with shortened time, and plan for preventive maintenance, saving both manpower and costs significantly.

- Reliable Network Communication

NR300 router provides reliable low latency communications, between machines and the center. Dual SIMs capabilities for redundancy mobile operator, switch cellular link between different 4G mobile data carriers.

- Working In Harsh Environment

With NR300, now it’s flexible enough with its strong and high EMC level design, it could get all equipment connected and have internet access to be online for remote visitors all the time.

Customer_Feedback

More and more provincial electrical companies are beginning to deploy more NR300 in their electrical panels. Each of these provinces will have new phases to expand their infrastructure, and each of these is a potential position for future sales in high numbers.
