Abstract


With the growing global energy crisis and environmental pollution problems, the development and utilization of clean, renewable energy is imperative. Solar energy is the cleanest in the world, the most realistic, the most prospects of large-scale development and utilization of renewable energy sources. The use of solar photovoltaic been widespread concern around the world. The solar energy is inexhaustible and clean and safe, the ideal renewable energy. Solar photovoltaic technology as an important part of the utilization of solar energy, and is considered to be the 21st century, the greatest potential for development of a power generation. The study of the solar photovoltaic power generation system has important implications for the mitigation of energy crisis, reduce environmental pollution as well as reduce the greenhouse effect. Solar array is part of the energy supply of the photovoltaic power generation system and one of the core components of the photovoltaic power generation system, the paper first introduces the composition and characteristics of the photovoltaic system, intensity of solar radiation and temperature of the solar array given the mathematical model of the solar cell, about the maximum power point tracking (MPPT), and the maximum power point tracking method used in this paper are described in detail. Stand-alone PV systems used in the battery pack, battery accounted for the proportion of the entire cost of PV systems is relatively large, and easily damaged, so the paper describes the characteristics of the sealed VRLAB and design characteristics of the battery, a way to achieve the \Widely independent solar photovoltaic power generation system, the system DC / DC converter topologies and their advantages and disadvantages are summarized choice of the Boost circuit level as battery before MPPT circuit, and its main circuit The parameters of the design. Inverter system circuit using Boost circuit to boost power to the load, and then with a full-bridge inverter circuit. Photovoltaic system inverter structure and control strategy, the article uses the improved fixed-frequency SPWM current control strategy, the better to achieve a sinusoidal current output of the inverter control, hardware circuit design TMS320F2407A DSP-based control system and software design. The system to achieve better control scheme proposed in this paper, the completion of the design, experiments show that the control scheme is simple and feasible, the system is stable and reliable, good performance.
