Abstract

In this paper, a power facility communication control device was designed to autonomously determine and separate the fault section through communication between power facilities in the smart grid distribution system. In the power facility communication control device, the control module was designed as a DSP to measure three-phase voltage and current, and the communication module was designed as an embedded-based Raspberry Pi to determine the fault section and realize the fault section separation through communication between power facilities. Communication between DSP and Raspberry Pi was designed by SPI communication, and communication between Raspberry Pi was designed based on Wi-Fi. Finally, a performance evaluation system based on three power facility communication control devices was built, and simulation verification was conducted for various fault events that may occur on the distribution line. As a result of the test evaluation, it was possible to confirm the effectiveness of the design methodology of the communication control device by showing the required response of the communication control device to all test cases.

본 논문에서는 스마트 그리드 전력설비 간 통신을 통해 고장구간을 자율적으로 판단, 분리하기 위한 기반기술인 통신제어장치를 설계하였다. 통신제어장치에서 제어모듈은 3상 전압, 전류를 계측할 수 있도록 DSP, 통신모듈은 전력설비 간 통신을 통해 고장구간을 판단, 고장구간 분리를 실현할 수 있도록 라즈베리 파이로 설계되었다. DSP와 라즈베리 간 통신은 SPI 통신방식을 기반으로, 반면에 라즈베리 간 통신은 Wi-Fi 기반으로 설계되었다. 끝으로, 3개의 전력설비 통신제어 장치로 구성되는 성능 평가 시스템을 구축하였으며, 선로 상의 다양한 고장 이벤트들에 대한 모의 검증을 실시하였다. 평가 결과, 모든 시험경우들에 대해서 통신제어장치가 요구된 응답을 보임으로서 통신제어장치 설계 방법론의 유효성을 확인할 수 있었다.
