Photovoltaic power generation system to solve the problem of world agricultural water

Check-out car adopts modular design, photovoltaic power station adopts the distributed data acquisition system, can deal with the scene area is large, object wide distribution, mass test of channel number. At the same time according to the number of the test object, the distance and the number of channels

photovoltaic power station test car adopts modular design and distributed data acquisition system, can deal with wide field, distribution of large objects, multi-channel extensive testing. At the same time, the number of data acquisition system based on field test object, layout and installation can be the number of channel number, distance, and flexible configuration. The test car adopts the high precision, high reliability, high synchronicity, good adaptability, and the design of the portable, can ensure the accuracy and reliability of the test data, test equipment can adapt to various environment, easy to operate. Data collection, analysis and evaluation software is data collection and record, man-machine interface and data management functions, which can realize the online data processing and analysis, basic information and key components of power station real time parameter display, view the history data and curve, fault alarm and prompt, automatic generation of test reports and other functions. Photovoltaic power station check-out car can be in accordance with the relevant national standards and solar photovoltaic power generation systems and wind power generation system of the Chinese Academy of Sciences quality test center of the grid photovoltaic power station on-site technical specification for test and evaluation for testing. Check and evaluation content includes power station after the completion of a comprehensive inspection and acceptance, regular inspection and maintenance of quality within the plant life cycle, and power plant during and after inspection and acceptance of performance evaluation on a regular basis. The concrete content includes: power station appearance inspection, the components and the overall inspection, the power station running state examination, power station power generation energy diagram, performance analysis, the power factor and equivalent power generation time, normalized loss, pv array prediction efficiency, power efficiency, power generation, etc. China accounts for 4% of the world's arable land, behind the United States, Russia and India. More worryingly, 55% of the arable land in China is a drought. Relying on the weather for food is true portraiture of the upland farmers' life. With global warming, the weather is changeable, agriculture increasing demand for irrigation equipment. How to solve the problem of agricultural drought and irrigation water shortage? In the grid infrastructure developed, complete, can easily solve this issue. However, that grid is difficult to cover the place? Photovoltaic (pv) water pumping technology is in recent years in yunnan province promoted a new water technology, the development momentum. In addition, in yunnan province implemented a case, the successful application of a batch of high quality effect is remarkable. 'Solar photovoltaic water technology is developing rapidly in recent years a integrates light system. It USES continuous energy from the sun, by multiple series and parallel solar arrays of solar cells, modules to absorb solar radiation energy, and convert solar energy into electricity, to power the entire system. Photovoltaic pump inverter control and the operation of the control system, convert the solar cell array produced by the direct current into alternating current (ac), drive pumps, according to the changes of the intensity of sunlight in real time to adjust output frequency, so as to realize high power point tracking, to maximize the use of solar energy. 55% of dry land water shortage in China, even if only 1% of the arable land use pv pump technology, also can form a market of 400000 megawatts of installed. 1 gw installed solar pv pumping equipment can meet the demand of 5 million to 10 million mu of land. In addition, a lot of power required of the traditional water conservancy construction laid, reservoir construction and trench excavation, compared to the overall investment scale vary widely. Photovoltaic water conservancy of global ecological and environmental friendliness make it has more advantages.
