Description
Technical field
The utility model relates to a kind of photovoltaic power station component cleaning device, also known as photovoltaic power station component clean robot.
Background technology
The system effectiveness of photovoltaic plant weighs the most direct standard of running situation, and when solar irradiation resource is determined, system effectiveness determines the generated energy of a photovoltaic plant.When carrying out design of photovoltaic power station, all will carry out analogue simulation to the annual electricity generating capacity of photovoltaic plant, correspondence determines a rational system effectiveness, as the normative reference of later stage operation maintenance.The gross efficiency of grid-connected photovoltaic power generation system by the efficiency of solar cell array, inverter efficiency, exchange grid connection efficiency three part and form.
Solar cell array efficiency eta 1, under solar battery array is listed in intensity of solar radiation, the DC output power of reality and the ratio of theoretical power (horse-power).The loss that solar battery array is listed in power conversion and transmitting procedure mainly comprises: component matching loses, surperficial dust eclipsing loss, spectral mismatch lose, the impact of temperature and DC line loss etc.
Inverter efficiency eta 2, the AC power of inverter output and the ratio of DC input power.Wherein loss mainly comprises inverter conversion loss, MPPT maximum power point tracking (MPPT) loss of significance etc.
Grid connection efficiency η 3, namely exports from inverter and is then incorporated to the efficiency of transmission of 35kV or 110kV transformer station through 10kV boosting, wherein the line loss that is connected with alternating-current electric of the loss in efficiency of loss importantly step-up transformer.
To sum up, the gross efficiency of photovoltaic power station system is η=η 1* η 2* η 3, in the Power Plant Design stage, the measure Loss reducing such as photovoltaic array layout optimization, electrical component flow point shelves can be passed through, improve system effectiveness, when key equipment type selecting, strict management and control is carried out to the performance of assembly and inverter, the reliability and stability of photovoltaic plant can be improved.
Generating equipment most crucial in photovoltaic generating system is solar photovoltaic assembly, the height of its photoelectric transformation efficiency, directly affects the generating efficiency of photovoltaic generating system.Because photovoltaic plant is built in the severe place of the natural environment such as desert, wasteland mostly, the bad weather such as high wind sand, heavy rain snow often can be run into.The clean-up performance on photovoltaic module surface directly has influence on the generating efficiency of photovoltaic module, and serious meeting causes photovoltaic module to produce hot spot effect, reduces the photoelectric transformation efficiency of photovoltaic module, thus affects the generating efficiency of whole photovoltaic generating system.Therefore, photovoltaic module cleaning scheme is a first-class difficult problem for puzzlement power station operation maintenance personnel always, adopts a kind of efficient cleaning mode to become to improve power station generated energy the topic that insider inquires into always.
In order to reduce the impact that dust covers, need to carry out periodic cleaning to assembly.In existing photovoltaic power station component cleaning method, manual cleaning is current most popular mode.According to statistics, 1 people's every day 100m capable of washing
2, 1MW photovoltaic module is about 6600m
2, needed for 66 man days.By everyone 80 yuan of/day estimations, 1MW assembly cleaning cost of labor is once 5280 yuan.By cleaning in 1 month 3 estimations, the annual cost of labor of 1MW is 190,000 yuan.Therefore, manual cleaning, employment is many, workload is large, and cleaning efficiency is low.Proficiency's difference causes that cleaning course is wayward, cleaning effect uniformity is poor.Manual cleaning has wearing and tearing to assembly glass, affects light transmittance and life-span.Be exactly adopt giant cleaning in addition, the general water supply of mobile waterwheel or the buried tubular type of adopting supplies water.Supply water according to mobile Waterwheel-type, then need waterr transporting vehicle and driver, according to the mode of water piping, then need to increase a large amount of up-front investments.Its advantage is that cleaning performance is good, more totally.Its shortcoming is that water consumption is large, and the water consumption that 1MW cleans at every turn about 10 tons, is not suitable for water-deficient area.Adopt spray system cleaning besides.Sprinkling equipment needs every square meter approximately to need the cost of increase by 35 ~ 50 yuan, amounts to initial outlay 0.2 ~ 0.3 yuan/W.Its advantage does not need manually, and cleaning speed is fast; Be particularly suitable for the power station of the manual cleaning inconvenience such as roof photovoltaic.Shortcoming is that cleaning performance is not fine, and water consumption is comparatively large, the water consumption that 1MW cleans at every turn about 6 ~ 7 tons.4th kind of method adopts the cleaning of vehicle-mounted professional cleaning equipment.Its advantage is that water consumption is less, the water consumption that 1MW cleans at every turn about 5 tons.Cleaning speed is fast, and cleaning performance is good.Its shortcoming can only be applicable to assembly fore-and-aft clearance comparatively greatly, and physical features is more smooth, the good place of geology; Along with the on-rectilinear movement of vehicle, the pressure size that assembly receives is uneven; Technical professional is needed to operate.
A kind of method is also had to be adopt cleaning robot cleaning.By the method that compressed air purges, compressed air purges, can using water wisely.Another kind be round brush add water spray mode clean.At present, the cleaning equipment major part that disclosed data and market can be seen is band water cleaning way, due to west area water resources shortage, easily freezes at severe cold weather, causes water-washing method to have significant limitation.Also have the mode of mode automatic cleaning disclosed in some to solve, but easily skid due to the limitation of type of drive and require very high to the smooth degree of assembly, climbing capacity is poor.
