TETRA(Terrestrial Trunked Radio) is the standard of D-TRS(Digital Trunked Radio System) developed by the ETSI(European Telecommunications Standards Institute). Currently, TETRA has been selected as Electric Power IT Wireless Backbone Network. Traditional distribution automation system has used the wireless network of Mobile Service Provider using CDMA(Code-Division Multiple Access) and WCDMA(Wideband CDMA) modem. Therefore, the development of gateway platform is indispensable according to the change to TETRA network. In this paper, we propose an embedded Linux-based Gateway platform for transmitting Industrial Electric Power IT protocol using TETRA network.

본 논문에서는 대표적인 산업용 프로토콜인 DNP(Distributed Network Protocol) 3.0과 TETRA(Terrestrial Trunked Radio)의 Gateway System Architecture를 제안한다. TETRA는 재난망 무선통신 기술로써 여러가지 타입의 무선 인터페이스를 제공한다. 이러한 TETRA 기술을 이용해서 원거리에 있는 각 산업용 장비들의 감시 제어를 보다 효율적으로 수행 할 수 있다. 하지만 아직 TETRA의 국내 표준이 이루어지지 않은 상태이기 때문에 본 논문에서는 다양한 산업용 장비와 인터페이스를 할 수 있는 표준을 제공하고자 한다.

TETRA is the standard of Digital Trunked Radio System suggested by the ETSI(European Telecommunications Standards Institut ). It is adopted as Electric Power IT Wireless Backbone Network in Korea. Police station and Fire Station are using TETRA network. Currently, Power Automation Protocols are DNP3.0 in Distribution Automation System, DLMS in Auto Metering Infrastructure, IEC61850 in Substation Automation. These protocols are transmissions using CDMA or WCDMA modem. If Power Automation protocol uses TETRA networks, it can be interoperable with the systems in police or fire stations. And it has outstanding ability to handle problems in a disaster situation. So, This paper propose a gateway system of Power Automation which can transmit the power automation protocol using TETRA.

D-TRS is a method of wireless communication. This method will be able to use several frequency for multiple user used chanel together. TETRA of D-TRS technology is not rented network. Using TETRA network has the strong point which cost better than CDMA network of rental network. Master server of SCADA(Supervisory Control And Data Acquisition) system is realtime supervise control and a data acquire the control system or the RTU(Remote Terminal Unit). The present paper is developed and proposal the gateway platform for electronic power backbone network based on D-TRS. This gateway platform is converted DNP3.0 messages with TETRA PDU and converted TETRA PDU with DNP3.0 messages. Master server and FRTU will be able to send and receive DNP3.0 message via TETRA network using this gateway platform.

송변전자동화시스템에서 사용하는 주장치 와 RTU간에는 무선 통신망으로 TRS(Trunked Radio System), CMDA(Code Division Multiple Access) 그리고 에어미디어망을 사용하고 있다. 특히 디지털 TRS기술인 유럽 전자 통신 표준기구인 ETSI에서 개발한 TETRA는 임대망인 CDMA와 에어미디어망과는 달리 비임대망으로 비용적인 장점을 가지고 있다. 본 논문은 송변전자동화시스템에서 주장치 기능을 하는 DNP3.0 주장치 서버와 RTU의 기능을 하는 FRTU간에 TETRA 망을 사용할 수 있도록 MFTG(Multi Function Tetra Gateway) Platform을 구현하였다.

TETRA(TErrestrial Trunked RAdio) is wireless communication system generally adopted to public network and backbone network, as the technology of Trunked Radio System specified by ETSI(European Telecommunications Standards Institute) and currently adopted to the Electric Power IT Backbone Network in Korea. DLMS(Device Language Message Specification) is used in order to meter an electric measuring instrument value. In this paper, DLMS Server and Client simulator are used based on Window operating system. The multi-functional gateway, which transforms the communications based on RS-232C between DLMS Server Simulator and Client Simulator to the one based on TETRA PEI(Peripheral Equipment Interface), is developed such that DLMS SCADA(Supervisory Control And Data Acquisition) system is constructed based on TETRA.

본 논문은 산업용으로 널리 사용되고 있는 DNP3.0(Distributed Network Protocol)과 국가 긴급 재난망으로 사용되고 있는 TETRA(Terrestrial Trunked Radio)간의 소프트웨어 및 하드웨어 인터페이스를 정의하였다. 전재 사용중인 DNP3.0의 전송 방식의 문제점을 살펴보고, 이에 대한 해결방안으로써 TETRA를 제안함으로써 좀 더 안정적인 데이터의 전송과 TETRA 망의 이용 극대화를 이룰 수 있다.
