Research on Small-scale Wind/Solar Hybrid Generation System
Abstract How to solve the energy crisis has become the world's attention. Solar and wind energy are currently available in several renewable energy used widely. In this paper, considering the complementary of solar and wind energy in resource conditions and technical aspects. I establish a rational way of economic power which is small wind and solar power generation system.
This paper describes the new energy and new energy technologies briefly and reviews the domestic and foreign research status and development trends of wind and solar power generation systems ,which also discusses the composition and working principle of small wind and solar power generation system , a detailed description of the operation principle and features of the wind turbine generators , photovoltaic array, batteries, inverters,controllers and some important parts. In addition , the control strategy of wind power , photovoltaic power generation and battery charging are analyzed , focusing on the maximum power point tracking control , and on this basis, I summarize the overall control of a workable solution. In the end, I design circuit wind and solar controller by combining with practical engineering, in which I use the voltage and current Hall Hall to realize the real-time sampling of the fan voltage , solar battery voltage, battery voltage and charging current and use the EVA and AD software module of TMS320F2812DSP to achieve the battery under voltage , overvoltage, operation and other modes smart charging and discharging management. For output voltage fluctuations of wind turbines big problem , the system provides hardware and software intelligent fan over speed protection system .
