Today's worldwide environmental pollution and energy shortage have forced people to work harder to find and develop new energy sources. In the process of searching for and developing new energy, people naturally set their sights on various renewable alternative energy sources. Photovoltaic power generation is one of them. Solar photovoltaic power generation is a huge amount of renewable energy that is clean and pollution-free. "Photovoltaic power generation" is a form of power generation that directly converts the light energy of sunlight into electrical energy. Therefore, in recent decades, it has been more and more favored by everyone. Developed countries have set off a climax in the development of photovoltaic grid-connected systems. The use of solar photovoltaics has been rapidly developed, especially the development of "rooftop photovoltaic grid-connected systems." Therefore, the development of solar energy is of great significance whether it is from the perspective of social sustainable development or from the protection of the ecological environment.
China is no exception, and it is also facing major problems of energy crisis and deterioration of the ecological environment. Moreover, China has a large population and needs more energy. Fortunately, China is one of the countries with abundant solar energy resources, so China urgently needs to vigorously develop solar energy. With the gradual shortage of fossil energy sources such as coal, oil, and natural gas, and the increasingly serious energy crisis, solar energy is the most suitable, safest, and ideal alternative energy source for mankind in the future.
Photovoltaic is the abbreviation of solar photovoltaic power generation system. It is a new type of power generation system that uses the photovoltaic effect of solar cells-semiconductor materials to directly convert solar radiation energy into electrical energy.
The photovoltaic power generation system consists of the following three parts: solar cell components; power electronic equipment such as charging and discharging controllers, inverters, test instruments and computer monitoring, and batteries or other energy storage and auxiliary power generation equipment. The solar power generation system has two methods: an independent system and a grid-connected power generation system. The independent system needs to use a battery as an energy storage unit.
Grid-connected solar power generation system: It is composed of photovoltaic modules (square array) and photovoltaic grid-connected inverter power supply devices. Photovoltaic components (square array) convert solar energy into DC power, and convert DC power into AC power with the same frequency and phase as the power grid through the grid-connected inverter power supply and feed it into the power grid. The grid-connected inverter power supply is the core equipment of the photovoltaic grid-connected power generation system.
The contents of photovoltaic grid-connected inverter power supply devices include: photovoltaic grid-connected inverters, DC power distribution cabinets, photovoltaic power station monitoring systems, and environmental monitoring stations.
Photovoltaic power station remote monitoring system: including monitoring device, communication device, monitoring host and software, remote control system and device. The remote monitoring system is a very important part of the high degree of informationization, and EVOC's MEC-4005 fanless embedded machine is mainly used in the remote monitoring system of photovoltaic power plants.
System Requirements
Because the photovoltaic power generation system equipment needs to operate continuously and stably for a long time under complex environmental conditions such as high temperature, low temperature, humidity, dust, etc. outdoors or even in the wild. If the equipment is able to work in a wide temperature range and a wide humidity range, the system can effectively perform the remote monitoring function of the equipment without maintenance or a small amount of maintenance. Only a fanless embedded industrial computer can meet the requirements of system control. In addition, because the efficiency of photovoltaic power generation itself is low, and the industrial computer monitors the operation status and data of all grid-connected inverters 24 hours a day, the industrial computer requires lower power consumption products, and only choose lower power products. The fanless embedded industrial computer with power consumption can meet the requirements.
Combining the above factors, the most ideal state is a fanless machine that requires high reliability and high performance. This is also one of the biggest advantages of Anrecson's embedded fanless machine.
