Overview

TIM foils or otherwise known as graphite sheet have been introduced in use in ACS800 mod

ules using EconoPACK+ IGBT as part of normal continuous improvements in the ACS800

product family. Benefits of using TIM foils in comparison to thermal grease are easier installa

tion and more durable heat transferring properties for longer periods of time. Durability par

ticularly improved in a cyclic application.

Where and how to use

TIM foils are used to transfer the heat generated in the IGBT’s to the heatsink. Full instruc

tions on how to install TIM foils is described in document delivered with TIM IGBT spare part

kits. It’s possible to use a mix of IGBT’s with thermal grease and TIM foils. In parallel con

nected R8i modules it’s also possible to use a mix of modules using TIM foils and thermal grease.

Modbus RTU to Modbus conversion

Modbus field devices use usually serial mode (RTU or ASCII)

protocol while the SCADA communication uses TCP/IP based

Modbus TCP protocol. The Modbus user community has

defined the functionality for required protocol integration, that

is, how the Modbus RTU devices can talk to the Modbus TCP

SCADA system. This functionality is a protocol conversion

and it is implemented in ARC600. Many industrial devices like

PLCs and RTUs support RS-485 Modbus RTU mode. In

RS-485 mode, ARC600 can integrate unlimited number of

serial slaves to TCP/IP network (SCADA).

ARC600 has two application serial ports. Serial port 1 is

configurable to either console or data mode and it supports

only RS-232. while serial port 2 is configurable to multiple

serial modes (RS-232/RS-422/RS-485). Serial port

connectors are 9-pin D-sub (male) connectors.

Modbus to IEC-104 conversion

ARC600 provides support for generic Modbus RTU and

Modbus TCP devices such as ABB’s RIO600. In addition,

support is also provided for the preselected Modbus

parameters for Fault Passage Indicators (FPI). Currently,

Horstmann Compass B and Kries IKI-50 are supported.

ARC600 polls the fault indicator devices, connected to the

serial port, using Modbus protocol and converts the values to

IEC 60870-5-104. Up to four fault indicators can be

connected to one device. IEC 60870-5-104 is used to

communicate towards a SCADA via the Arctic M2M Gateway

over the available customer chosen cellular data network.

IEC-101 to IEC-104 conversion

With ARC600. conventional IEC 60870-101 serial devices can

be attached to a modern TCP/IP based IEC 60870-5-104

control system. This is enabled by the protocol conversion

from IEC 60870-5-101 to IEC 60870-104. In this case,

ARC600 (IEC-101 master) uses local synchronous data

polling where it continuously sends requests and the IEC-101

device (IEC-101 slave) responds. In the direction of the

control room, the communication protocol is IEC-104 and

ARC600 can send events asynchronously as they arise while

SCADA performs only slow-period background scans.

Another advantage of the local protocol conversion is an

advanced data acknowledgement mechanism. IEC-104

allows multiple packets, and multiple events in a single

packet, to be acknowledged collectively and the packets can

be buffered up to the time of acknowledgement from SCADA.

Communication

Wireless Controller ARC600 provides a complete solution for

monitoring and controlling field devices. A secure

communication channel can be formed for remote serial

(RS-232/RS-485) or Ethernet field devices over a GPRS, 3G

or LTE connection. ARC600 makes it possible to have cost

effective communication networks over long distances at high data rates.

Several interfaces are available for field device connectivity:

digital inputs and outputs, analog inputs, serial and Ethernet

ports. Industrial protocols IEC-104. IEC-101 and Modbus

TCP are supported for the SCADA connectivity. The inputs

and outputs of ARC600 can be accessed and controlled with

the IEC-104 and IEC-101 protocols.

With the Wireless Controller ARC600 protocol conversion

feature, conventional IEC-101. Modbus RTU and Modbus

TCP devices can be connected in a reliable way to modern

TCP/IP based IEC-104 control systems.

Application

The functionalities of Wireless Controller ARC600 have been

developed to monitor and control switching devices inside a

secondary substation. Connected to the central control

system (SCADA/DMS) that manages the utility network, they

serve as the core of the secondary substation automation system.

Key features

• Highly reliable control and monitoring of up to three

switching devices per ARC600– Status information of three switching devices and

three earthing disconnectors– Disconnector position and earthing status indications

with front LEDs– Local and remote use of the disconnectors

• Overload protection of actuator motors– Load current measured in the motor circuit– Current limit based motor overload protection

(software fuse)– Measurement of disconnector open and close times

• Fault Passage Indication (FPI) support for improved fault

management– Support for external medium voltage directional fault

indication and for multifunction low voltage power quality metering

• Integrated wireless communication– Always on two-way communication based on cellular

networks (GPRS, 3G, LTE)– Communication monitoring and automatic connection

re-establishment– High level data security through internal VPN and

Firewall– Support for Arctic Patrol centralized device management application

• Protocol converter– Conventional IEC-101 and Modbus serial devices can

be connected in a reliable way to the modern TCP/IP

based IEC-104 and Modbus TCP control systems

• Built-in battery charger with advanced battery control– Temperature compensated charging– Battery monitoring/testing (condition monitoring)– Deep discharge protection

• IEC-101 SCADA compliancy– IEC 60870-5-101 slave (including dial-up) to support

the existing system installations– Possibility for future SCADA migration from IEC-101 to

IEC-104 is supported as the operating mode is

selected using the parameter settings– IEC-101 operation mode as unbalanced slave

• Heater control to limit the effects of ambient temperature

variations such as condensation

• Robust aluminium casing design and easy DIN rail mounting

The use of Wireless Controller ARC600 in distribution

networks improves the quality of power distribution and

reduces the outage time in the affected areas. Areas directly

adjacent to these affected areas show reduced outages and

overall effects. This also reduces the capital expenditures in

the distribution network by allowing integration of legacy

devices and contributes to more direct cost savings by

facilitating preventative maintenance. The operational

expenditure can be reduced by lowering the System Average

Interruption Duration Index (SAIDI) and System Average

Interruption Frequency Index (SAIFI), resulting in lower

penalties for undelivered energy. Wireless Controller ARC600

is also ideally suited to be retrofitted to existing applications

thus enabling the remote control of these devices and further

extending the life cycle of the switching devices itself.

Typically, the IEC-104 protocol is utilized for communication

to the SCADA system but for the existing installations with a

IEC-101 line or modem, Wireless Controller ARC600 supports

also IEC-101 communication (including dial-up) to the SCADA system.

Description

Wireless Controller ARC600 is a compact, solution based

device for remote controlling and monitoring of secondary

substations, such as network disconnectors, load break

switches and ring main units (RMU) in distribution networks. It

enables the SCADA system to wirelessly monitor and control

the field devices over the public communication infrastructure

(cellular network). Wireless Controller ARC600 utilizes the

built-in wireless communication features for reliable and

secure end-to-end communication providing remote

monitoring and control of three switching devices and can be

expanded as required by using external I/O expansion modules.

The use of Wireless Controller ARC600 in distribution

networks improves the quality of power distribution and

reduces the outage time in the affected areas.
