Abstract

Because wind turbines are larger and more off-shore construction due to economic and environmental factors, it is more difficult to access the wind turbine as well as the necessary parts and the maintenance costs are increasing. So, we need to minimize fault elements and to prevent a secondary accident at failure through monitoring to reduce maintenance costs and to increase reliability of operation. In this paper we have implemented ZigBee based wireless sensor nodes and network for wind turbine condition monitoring using temperature, humidity, voltage, current, wind direction, and wind speed sensors. ZigBee wireless sensor nodes signals are transmitted to a central monitoring system via routers. Also, the sensor signals are collected and processed using LabVIEW program to monitor the wind turbine conveniently. The administrators and users can monitor the condition of wind turbine at remote site in real time over TCP/IP.

풍력발전기가 경제적, 환경적 요인에 따라 대형화, 해상화 되고 있어 접근이 어렵고, 부품 및 유지보수 비용이 증가하고 있다. 풍력발전기 상태 모니터링을 통하여 고장 요소를 최소화 하고, 고장 시 2차 사고를 예방하여 운영유지 및 보수비용을 낮추고 신뢰성을 증가시켜야 한다. 본 논문에서는 IEC 61400-25-2에서 표준으로 추진하는 풍력발전기 모니터링에 적합한 센서 중 실제 풍력발전기 상태 모니터링에 필요한 온도, 습도, 전압, 전류, 풍향, 풍속 센서를 ZigBee 무선 통신 소자와 결합하여 무선 센서노드를 구성하고 이를 이용한 간단한 네트워크를 통하여 센서 신호를 전송한다. 각 무선 센서노드에서 전송되는 신호는 라우터를 통하여 중앙 모니터링 터미널에 전송한다. 또한 LabVIEW로 신호를 수집 및 처리하고, TCP/IP 통신 변환을 통해 인터넷 환경이면 언제 어디서든지 사용자 및 관리자가 모니터링 할 수 있도록 한다.
