Abstract

Electrical energy is the essential resource for modern society. Recently, the demand for power was significantly increased. Increase of power demand has lead to a decrease in the power quality. Power quality in modern society has been an important factor that can cause a major problem throughout the home and general industry. Therefore, we need a system for preventing the power quality problems. To avoid power issues, it is important that the measurement of the power quality and initial response. In this paper, we propose real-time power quality measurement system and harmonics monitoring system. We design the system using DM240001 board include dsPIC33FJ256GP710A of microchip. This system can adapt three-phase three-wire system. And optimized the algorithm, we can measure momentary changes of the power system. In addition, designed system can measure harmonics distortion like to VTHD, ITHD and ITDD for 31th harmonics.

전력은 현대 사회를 구성하는데 있어 필수적인 자원이다. 최근, 전력에 대한 수요가 급격하게 증가하였으며 전력 수요 증가는 전력 품질의 저하를 야기하였다. 현대 사회에서 전력 품질은 일반 가정과 산업 전반에 걸쳐 큰 문제를 일으킬 수 있는 중요한 요소가 되었다. 전력 품질 문제를 예방하기 위해서는 전력 품질에 대한 계측과 초기 대응이 중요하다. 본 논문에서는 실시간으로 전력 품질을 계측하고 고조파를 분석하여 모니터링 할 수 있는 시스템 제안한다. 마이크로칩의 dsPIC33FJ256GP710A칩을 이용한 DM240001보드를 이용하여 최대 3상 3선에 해당하는 배선 방식의 전력 품질을 계측하는 시스템을 설계하였고, 계측 알고리즘의 최적화로 전력 품질의 순간적인 변화를 측정할 수 있도록 하였다. 또한, 최대 31차에 해당하는 고조파들에 대하여 전압과 전류의 왜율과 수요 전류 왜율에 대해서도 측정 가능하도록 설계하였다.
