Research On The Reliability Of Double Axis Solar Photovoltaic Power Generation Automatic Tracking System

In today’s growing shortage of traditional energy, in response to the energy crisis and the development of alternative energy is the top priority of the future energy strategy. Solar energy as a common, harmless, huge, long-term new energy, much favored by domestic and foreign various techniques and equipment have emerged as to improve the utilization of solar energy photovoltaic solar tracking system is one of the representatives. Because of its installed outdoors, so that the environment, material selection, design and other factors will inevitably affect the service life of solar photovoltaic tracking system, so research to improve their job stability, performance and reliability of equipment service life of solar photovoltaic power generation Automatic Tracking System and market competitiveness, and the popularity of solar energy utilization are important.In view of the existing single and biaxial shortcomings and inadequacies of automatic tracking system of the solar photovoltaic power generation, comprehensive analysis system for mechanical structure part and electric control part of the whole system reliability, the influence of the joint tracking mode solution formulation, the design of the composite control strategy and system set of general software scheme of biaxial overall reliability of the automatic tracking system of the solar photovoltaic power generation system research.Adopt joint tracking mode can be adapted to changes in the weather, not only to solve the problems brought about by way of a single track, in case of cloudy or rainy days make real-time tracking mechanism erroneous rotation, but also allows the tracking control system failure, the need for human periodic adjustment mechanism accumulated error and other issues, but also to ensure biaxially automatic tracking solar photovoltaic systems are designed to run trouble-free service life, improve system reliability.Depending on the load on the truss material, the stent design and motor selection, use Proe overall three-dimensional modeling software system, Fluent software for solar PV panels suffered were static wind load simulation analysis, according to the results of the use of static pressure contours Ansys software overall force system simulation analysis, overall deformation and stress distribution diagram to determine the relationship between the load, material, structure and strength between.An increase of wind speed and direction detection module and the system automatically shelter design, greatly reduce the influence of high wind on the system, photovoltaic panels hot spot to solve the problem by adding a bypass diode failure methods, thus greatly improving the biaxial automatic tracking solar photovoltaic power generation system overall reliability, thereby prolonging the working life.
