Design Of The Control System Of The Bee Farm Wind-solar Complementary Power Generation Based On PLC Control

In the mobile bee field,due to the restriction of the environment,it is difficult to obtain the supply of electricity for the lighting and production of the bee field.At present,most of the bee field surveys have found that the honeybee field uses solar cells as the power element to power the load.The photoelectric conversion efficiency of photovoltaic power generation system has a great relationship with the illumination intensity,and the higher the light intensity is,the higher the photoelectric conversion efficiency is.But if use alone solar battery power supply,when there is no solar energy resources in rainy day,is not able to battery recharged,which can’t reach the request of power supply to the system.The current situation of electricity generation in the bee field is not enough to meet people’s daily electricity consumption.Whether it is a single wind system or a single solar system,it is constrained by natural conditions that limit the use of solar and wind power.However,if it can be used reasonably,combining the advantages of the two and giving full play to their respective characteristics,it can solve the problems of energy randomness and instability.As international scholars and experts to the use of wind and solar power made a more in-depth research,and achieved some results,especially the comprehensive utilization of wind energy and solar energy,combined with their own advantages and disadvantages more reasonable energy system is established.So we put forward a control system based on bee field.The main research contents of this paper are as follows:1.This paper introduces the working principle of the whole design,and makes a detailed description of each part,selects the control strategy suitable for this design,and makes the system run in the best working mode.2.Through data collection to determine the apiary electricity load,somewhere in bee field as an example to analyze its wind and light resources,calculation of wind machine,panels,inverter device,the capacity of energy storage device,and the capacity matching calculation and to establish the simulation of the system,make the design more accord with the actual application significance.3.Combined with power electronics technology and electronic technology,the design of the hardware control system of the system,including the design of Siemens PLC,has a good operation effect.4.Combined with PLC programming technology and STEP7 Mirco/WIN-V4.0,the software control system was designed and the software flow chart was determined.5.Through the experiment,the actual research on the power generation condition of the wind power system,the power generation condition of photovoltaic power generation and the three-phase charging of the battery are carried out,and the feasibility is proved.
