Study On The Control System Of Solar LED Street Lamp For The Plum Rains Climate

With the rapid development of solar photovoltaic power generation technology, LED street lamp energy-saving lighting technology gradually is spread in our eyes and solar LED street lighting technology is pregnant in these new two fields. The energy consumption of street lamp lighting accounts for a large part of the whole field, but the energy of solar LED street lamp comes from the sun as an independent system. It greatly saves resources in order to alleviate the shortage of resources on earth provides an efficient solution because of the perfect combination of Clean and inexhaustible solar energy and high efficiency luminous efficiency of LED lighting technology. More importantly, our ecological environment has been greatly improved for the efficient use of clean energy. Solar LED street lamp as a completely independent system, the battery is the only power supply LED street lighting and the generation in the day depends entirely on the local weather conditions. During continuous rainy weather rainy climate in some areas, the system will be forced to stop running,Because of the battery unable to obtain the electric energy for a long time.If the battery is in the feeding state for a long time, the service life of the battery will be greatly reduced.In this paper, a kind of charging and discharging management system for street lamp is studied for the special plum rains climate. First of all, this paper makes a statistical analysis of the electricity generation in the area in recent years, and extracts the characteristic vector of the plum rains climate, which provides the basis for the identification of the special weather for the control system. Under normal circumstances, the control system is used to adjust the driving power of the LED street lamp by using the moving average method, and the power saving strategy can be realized by the time-sharing power down strategy. Under normal circumstances,control system drive power coefficient of the moving average weather way to effectively regulating the LED lamp and using power reduction of time-sharing strategy to save energy. Through this special weather forecast, it can greatly extend the number of street lights, more importantly, can effectively extend the service life of the battery. The maximum power point tracking technology is added to the charging control strategy, which provides the most energy for the battery in the effective time.
