Application Research on the Control Model of Solar Photovoltaic Power Generation in Eco-agriculture

In order to further realize the deep coupling performance between agricultural facilities and solar photovoltaic power generation technology,the application of solar photovoltaic power generation control model based on the concept of ecological agriculture was studied with the example of green intelligent irrigation.On the basis of a thorough understanding of the components and generators of solar photovoltaic system with mature technology,combined with the energy flow characteristics and load structure of solar photovoltaic module,a power generation control model suitable for farmland irrigation equipment was established,then reasonable selection of system hardware and precise design of software control were carried out to form a complete solar photovoltaic power generation system and the application test was done,the results showed that the error between theoretical and practical power generation of the photovoltaic control system could be controlled within 5%under the experimental conditions of different operating speeds,which was in line with the actual farmland operation and the test results were good.The comprehensive performance efficiency of irrigation units could be maintained at an average of more than 85%.It would well promote the application of photovoltaic power generation technology in agricultural equipment and facilities,and provide a certain research direction for promoting the upgrade and development of ecological agriculture in China.
