Design And Implementation Of Photovoltaic Module NOCT Outdoor Test Data Acquisition And Processing System

Today, the rapid development of the global economy, China has become a leader in the development of global economy, the GDP data from year to year lead. Domestic economic development characteristics, especially iron and steel, glass and so on several major pillar industries, often bring a large number of energy consumption. Coupled with the basic energy brought about by the use of large population, China has become the leading global power consumption of traditional energy. As everyone knows, the traditional energy sources such as coal, burning large amounts of oil, in addition to will produce large amounts of carbon dioxide, the greenhouse effect; and also for the domestic haze weather seeds. Thus trigger hot debate can be heard without end. We have not only worry about what a large consumption of traditional energy and non renewable nature of the particles in the air, it will bring, deadly turbid, already let us begin to worry about their every breath. Therefore, the development and utilization of new energy, is the humanity in recent decades has continued the topic.With the large-scale development of solar energy industry,. China has become the photovoltaic manufacturing center. Each area Ling Lang everywhere, with photovoltaic products transported to all over the world, to use a plurality of photovoltaic power station and family. How to quickly understand the performance and safety of photovoltaic products, become a prerequisite for photovoltaic products selection. So on the basis of characteristics of PV module itself, to study its normal temperature of working condition, has become a research value has good direction. The research of this paper mainly focuses on the collection and processing of the battery temperature data outside the normal working state of photovoltaic components, mainly related to the measurement accuracy, synchronization and data processing technology.This paper analyzes the current IEC standard outdoor NOCT test, the key lies in the test part corresponding relationship related environmental conditions and component temperature, need to simultaneously fit between multiple variables, and the conditions for possible interference test results by eliminating. Combined the thinking, design the automatic acquisition and processing system on Windows platform running data. The system can monitor the operation is convenient, the environment factors of real-time dynamic and component temperature, can automatically display the current state of the system is running, the collected data curve, convenient for the user to view and judge. At the same time provide a variety of settings mode, let the user in the test conditions can be adjusted according to their own needs.Finally, after testing and inspection, the system can real-time collect the mutually corresponding to the various environmental conditions and component temperature, after data screening, can be directly obtained the test result, convenient, fast implementation of outdoor photovoltaic component NOCT test.
