본 발명은 태양광 발전시스템에 사용되는 태양광 발전소용 분전함에 관한 것으로, 보다 상세하게는 태양전지모듈에서 발전되어지는 전력을 측정하기 위한 전력계측장치를 태양광 발전소용 분전함 내부에 설치하여 분전함의 전력공급 기능에 부가하여 전력계측장치를 통하여 취득되어지는 전류, 전압 데이터를 활용하여 태양광 발전소의 연도별, 월별, 일별 발전량을 확인하고, 태양전지모듈 상태를 원방에서 점검하여 태양전지모듈의 경년열화 및 노후화, 자연재해로 인한 파손 등과 같은 문제 발생시 신속히 유지보수를 통하여 해결함으로써 최적의 상태에서 태양광 발전시스템을 운용하고자 하는 태양광 발전소용 분전함에 관한 것이다.The present invention relates to a distribution box for a photovoltaic power plant used in a photovoltaic power generation system, and more specifically, to install a power measurement device for measuring the power generated by the solar cell module in a distribution box for a photovoltaic power plant. In addition to the power supply function, the annual, monthly and daily power generation of the solar power plant is checked by using the current and voltage data acquired through the power measuring device, and the state of the solar cell module is checked by checking the state of the solar cell module remotely. The present invention relates to a distribution box for a photovoltaic power plant that attempts to operate a photovoltaic power generation system in an optimal state by quickly solving it in case of problems such as deterioration, aging and damage caused by natural disasters.

일반적으로, 태양광 발전은 반도체 소자인 태양전지판에 햇빛을 쏘이면 광전자효과를 일으켜 전기가 발생하는 원리를 이용하는 것으로, 무공해, 무소음, 무한에너지로서 대표적인 대체에너지 이용 시스템의 하나이다.In general, photovoltaic power generation uses the principle that electricity is generated by photoelectric effect when sunlight is emitted to a solar panel, which is a semiconductor device, and is one of representative alternative energy utilization systems as pollution-free, noise-free, and infinite energy.

또한, 태양광 발전시스템은 햇빛을 받아 직류전기를 생성하는 태양전지모듈과 생성되어진 전기를 제어해 주는 전력제어장치, 발생된 전력을 저장하는 축전지 (BATTERY), 그리고 직류전기를 교류로 바꾸어 주는 인버터(INVERTER)로 구성되어지며, 시스템 이용방법에 따라 산간, 벽지 및 섬 등의 원격지와 주택에 설치되는 독립형 시스템과 외부의 전선에 연결하여 사용되고 남은 잉여전력을 전력회사에 판매하는 계통연계형 시스템, 태양광 발전기에 디젤발전, 풍력발전 등을 복합적으로 연결하여 발전하는 하이브리드 시스템 등으로 구분할 수 있다.In addition, the photovoltaic power generation system is a solar cell module that generates direct current electricity by receiving sunlight, a power controller that controls the generated electricity, a battery that stores the generated power, and an inverter that converts direct current electricity into alternating current. It is composed of (INVERTER), and it is a grid-connected system that sells the surplus power used to the power company by connecting it to an independent system installed in remote places such as mountains, wallpaper and islands and houses according to the method of using the system, and to external power lines, It can be divided into a hybrid system that generates power by combining a solar power generator with diesel power and wind power.

상기의 태양광 발전시스템에 사용되는 태양광 발전소용 분전함은 태양전지모듈에서 발전되어진 직류전기를 인버터로 공급해주는 기능을 담당한다. 그 일례로서 도1에서와 같이 분전함 내부에는 전력을 원활하게 공급하기 위하여 난연성 케이블(10), 터미널 단자대(20), 전력용 퓨즈(50), 다이오드(60), 부스바(70), 차단기(80) 등이 설치되어 있어 이들 전력기자재를 통하여 전력의 공급, 과부하 또는 과전류 사고시의 전력차단이 이루어지게 된다.The distribution box for photovoltaic power plants used in the photovoltaic power generation system is responsible for supplying the DC electricity generated from the solar cell module to the inverter. As an example, the flame retardant cable 10, the terminal terminal block 20, the power fuse 50, the diode 60, the busbar 70, and the circuit breaker are provided to smoothly supply power to the distribution box as shown in FIG. 1. 80), etc., are installed so that power is cut off in the event of supply of power, overload or overcurrent accident.

그러나, 상기와 같은 분전함은 단순한 전력공급 기능만을 갖추고 있어 발전되어지는 발전량 확인, 태양전지모듈 상태, 전력품질 등과 같은 중요한 전력정보를 원방에서 실시간으로 취득할 수 없어 중앙감시반 근무자가 상시 분전함 내부를 측정장비를 사용하여 전력데이터를 취득해야 하는 문제점을 가지고 있으며, 이러한 현장에서의 작업은 안전사고를 발생시킬 수 있는 위험성을 가지게 된다.However, the distribution box as described above has only a simple power supply function, so important power information such as power generation check, solar cell module status, and power quality can not be obtained in real time from afar. There is a problem of acquiring power data using equipment, and work in such a site has a risk of causing a safety accident.
