ABB ARC 600 Wireless Controller Wireless Controller

Description

The wireless controller ARC600 is a compact solution-based device for remote control and monitoring of secondary substations in the distribution network, such

such as network disconnect switches, load disconnect switches and ring mains units (RMUs).

switches and ring mains units (RMUs) in the distribution network. It enables SCADA systems to wirelessly monitor and control field devices over the public communications infrastructure (cellular networks).

The wireless controller ARC600 utilises the built-in wireless communication capabilities for reliable and secure end-to-end communication.

Three switchgear devices can be remotely monitored and controlled, and can be expanded as needed using external I/O expansion modules.

The use of the wireless controller ARC600 in the distribution network improves the quality of power distribution and reduces outage times in affected areas.

Outage times and the overall impact on areas directly adjacent to these affected areas are reduced.

Additionally, by integrating legacy equipment, capital expenditures in the distribution network can be reduced and cost savings can be achieved more directly by promoting preventive maintenance.

By reducing the System Average Interruption Duration Index (SAIDI) and System Average Interruption Frequency Index (SAIFI), the

operating expenses can be reduced, resulting in lower penalties for undelivered energy.

The wireless controller ARC600 is also ideally suited for retrofitting into existing applications to remotely control these devices and further extend the life of the switchgear itself.

Communication with SCADA systems typically uses the IEC-104 protocol, but for existing installations using IEC-101 lines or modems, the ARC600 wireless controller also supports communication with SCADA systems.

The Wireless Controller ARC600 also supports IEC-101 communication (including dial-up) with SCADA systems.

Complete Communication System

The Wireless Controller ARC600 is often part of a complete communications system.

The system consists of an Arctic 600 series gateway or controller and a central M2M gateway, the ARM600 Communication Server.

The M2M gateway is an important part of the overall communications solution and has the functionality required to create a reliable end-to-end communications system.

- Static IP address for Arctic 600 series devices - standard SIM card can be used which is carrier independent

- VPN Concentrator - secure communications between a central location and remote sites

- Arctic Patrol - centralised device management application for monitoring Arctic 600 Series devices

- Firewall - network security system to control incoming and outgoing network traffic

Applications

The functionality of the wireless controllers ARC600 has been developed specifically for monitoring switchgear in secondary substations.

They are linked to the central control system (SCADA/DMS) that manages the utility network and are the heart of the secondary substation automation system.
