본 발명은 태양광발전기와 연결된 전력계통 설비의 장애를 검출을 통해 태양광발전소의 발전효율을 높이는 방법에 관한 것이다. 보다 상세하게는 데이터 수집 유닛(DATA Acqusition Unit : DAU)은 유무선으로 연결된 송전계통설비의 보호계전기와 태양광발전제어 및 모니터링 시스템으로부터 장애정보를 검출하고, 계통설비의 장애발생이 검출될 경우 유무선 네트워크를 통하여 관리자에게 알려주는 방법에 관한 것이다.
The present invention relates to a method of increasing the power generation efficiency of a photovoltaic power plant by detecting a failure of a power system facility connected to the photovoltaic power generator. More specifically, the Data Acquisition Unit (DAU) detects fault information from protection relays and photovoltaic control and monitoring systems of transmission system facilities connected by wired or wireless, and detects faults in system facilities. It is about how to notify the administrator through.

태양광발전은 화석 에너지를 활용하지 않고 태양광 패널에 입사된 빛 에너지를 직접 전기에너지로 변환시키는 발전방식이다. 초기 투자비용과 발전단가가 비싸다는 단점이 있지만, 반영구적인 수명과 무공해 천연 에너지원으로서 최근 화석연료 사용에 의한 지구온난화 등 환경오염의 해결책으로 그 사용이 점점 늘어나고 있다.
Photovoltaic power generation is a power generation method that converts light energy incident on a solar panel directly into electrical energy without utilizing fossil energy. Although the initial investment cost and the cost of power generation are expensive, it is being used as a solution for environmental pollution such as global warming by fossil fuel use as a semi-permanent life and pollution-free natural energy source.

이러한 태양광발전시스템은 발전한 전력의 이용방법에 따라, 발전 전력을 축전지에 저장하여 필요한 시간에 전력을 공급하는 독립형 발전시스템과 발전 전력을 부하에 공급하고 잉여전력을 계통에 공급하는 계통연계형 발전시스템으로 구분된다. 이중 계통연계형 발전시스템이 기존의 발전소를 대체하는 분산전원으로서 각광을 받고 있다.
The solar power generation system is a stand-alone power generation system that stores generated power in a storage battery and supplies power at a time required according to a method of using generated power, and grid-connected power generation that supplies generated power to a load and supplies surplus power to the grid. It is divided into systems. Dual grid-linked power generation systems are in the spotlight as distributed power sources replacing existing power plants.

계통연계형 발전시스템은 복수의 태양광발전 모듈들이 직렬로 연결된 복수의 태양광발전 패널들을 포함하는 태양광발전 어레이부, 상기 태양광발전 패널들로부터 출력되는 직류전력들을 병합하여 출력하는 출력부 및 상기 출력부로부터 출력되는 직류전력을 교류전력으로 변환하여 부하 또는 사용계통에 공급하는 인버터를 포함한다.
The grid-connected power generation system includes a photovoltaic array unit including a plurality of photovoltaic panels in which a plurality of photovoltaic modules are connected in series, an output unit which merges and outputs DC powers output from the photovoltaic panels; It includes an inverter for converting the DC power output from the output unit to AC power to supply to the load or the use system.

계통연계형 발전시스템은 태양광발전소 운전을 통해 생산된 전력을 한전 송전계통설비와 연계하여 고압송전로에 전송된다. 이때 고장지락 및 고장단락에 의한 송전계통설비 장애 또는 저압전송로에서 발생되는 순간 정전됨으로써 송전계통설비들의 정상동작 중단으로 인한 태양광 발전 및 송전이 중단되어 경제적인 손실이고 물론 송전설비의 고장으로 인한 위험을 초래할 수 있다.
The grid-connected power generation system transfers the power produced through the operation of the solar power plant to the high-voltage transmission line in connection with the KEPCO transmission system. At this time, due to fault ground and failure of transmission system facilities due to short circuit or failure of low voltage transmission line, solar power generation and transmission is interrupted due to interruption of normal operation of power transmission system facilities, and economic loss, It can be dangerous.

그러나, 종래의 태양광발전시스템의 모니터링 방식은 태양광발전시스템 자체장애상태는 모니터링되고 있으며, 태양광 발전소와 한전 발전송전로 사이의 송전계통설비의 장애감시는 거의 이루지지 않고 있다. 송전계통설비의 장애는 22.9KV 고압전류 역류에 의한 트랩(Trap)이나 태양광발전소 발전용량 과부하에 의한 트랩(Trap) 그리고 저압송전로의 정전에 의한 설비 동작중단등 송전계통설비 장애감시는 한전의 배송전로 관리체시스템이나 태양광발전제어 모니터링시스템 어디에서도 설비장애를 실시간으로 모니터링하지 않으므로써, 경제적인 손실은 물론이고 사고에도 무방비 상태로 노출되어 있다.
However, in the conventional monitoring method of the photovoltaic power generation system, the failure state of the photovoltaic power generation system itself is monitored, and the failure monitoring of the transmission system facilities between the photovoltaic power station and the KEPCO power transmission line is hardly achieved. The failure of power transmission system facilities includes traps caused by 22.9KV high-voltage current backflow, traps caused by overload of power generation capacity of photovoltaic power plants, and power line system failure monitoring. Neither the transmission line management system nor the photovoltaic control monitoring system monitors equipment failures in real time, leaving both economic losses and accidents unprotected.
