Energy - Power Dispatching Solution

Overview

The dispatching center and each substation use dedicated data lines provided by communication operators to access the transmission network via leased optical channels. A VPN is established on this network to create a power dispatching data system. The SCADA server at the dispatching center and the communication integration servers at each substation form a "point-to-multipoint" network for dispatching communication through the VPN.

Challenge

The customer needs a stable 3G/4G cellular solution to install in electrical panels, connecting RTUs/Controllers to the dispatching center. The solution must support Modbus, DNP3, and IPSEC functionalities.

Key Requirements for Power Dispatching:

  • Durable Design: Must operate reliably in humid and extreme temperature conditions.
  • Enhanced Features: Support for Modbus, DNP3, IPSEC, and port mapping.
  • Secure Service: Provide reliable and secure data transmission for real-time monitoring of remote RTUs/Controllers.

Solution

The NE2201-140 router, through its RS232 serial communication ports, reads data from RTUs/Controllers using Modbus and DNP3 protocols and transfers it to the electricity management company's data center. This solution is widely applicable in power transmission centers and substations.

Solution Advantages:

  • Cost Savings: The NE2201-140 enables real-time monitoring, quick fault response, and preventive maintenance planning, significantly reducing labor and costs.
  • Reliable Communication: The NE2201-140 Router ensures low-latency communication and dual SIM capabilities for network redundancy.
  • Adaptability to Harsh Conditions: Its robust design ensures continuous connectivity and remote access, even in challenging environments.
