Portable light overhead utility analog meter

Technical field

This utility model belongs to solar photovoltaic industry field, and in particular to a kind of portable light overhead utility analog meter.This In proportion micro, can mould in laboratory into a small-sized analog platform by traditionally industrial large-sized photovoltaic plant for utility model Intend the activity of industry spot power station, greatly reduce the operation of research solar power station and the experimental cost for monitoring.

Background technology

Solar energy is the inexhaustible regenerative resource of the mankind, with sufficient spatter property, absolute safety The advantages of property, relative popularity, certain long-life and non-maintaining property, the abundance of resource and potential economy, growing There is critical role in the energy strategy of phase.Therefore, with other new-generation technologies (wind-power electricity generation and biomass power generation etc.) Compare, solar energy power generating is a kind of tool sustainable development desired characteristics (most rich in natural resources and most clean power generation process) Renewable energy power generation technology.

Traditional large-sized photovoltaic power plant construction is costly, and is true production at large scale industry scene, to related electric energy matter Amount has strict requirements, even if so there are related cooperation in colleges and universities, it is also difficult to carry out scientific research simulation experiment.Propping up without related experiment Support, the research to solar power station is not just known where to begin yet.With continuing to increase for the input of teaching facilities in recent years, some colleges and universities The large-scale experiment room of solar photovoltaic power plant is occurred in that, there is the experiment porch of the complete solar photovoltaic power plant of a set of comparison.No The foundation for crossing these laboratorys be all on the basis of a huge sum of money input, laboratory get off easily will million, even Ten million rank.And large-scale power station is simulated completely in the design of such laboratory, the research to some profound levels still has very big Limitation, such as large-scale finished product inverter cabinet, the employing of switch board so that the running status in power station can not be stored up directly in the form of data Deposit, to subsequent analysis, research very big inconvenience is brought.

Conventional photovoltaic instruments used for education simple structure, achievable related experiment is limited, demonstration mostly as student, real training Platform, it is mostly that design basis is tested that its related experiment is also, such as solar electrical energy generation principle, inverter etc.；Due to design Function unicity and being related to test it is basic, it be but much not enough to use as scientific research apparatus.So being badly in need of one now Planting can preferably simulate the ruuning situation in true power station, have equipment carrying portable, cheap experimental facilitiess concurrently again.

In view of the foregoing, it is proposed that and devise a kind of portable light overhead utility analog meter, this utility model can The basic operation in the true power station of solar energy is enough realized, and completes the photovoltaic array energy conversion technology of traditional solar energy instruments used for education Experiment, the experiment of parallel network reverse power technology, controller for solar technology experiment, simulation complex environment under power station running status, The basic functions such as off-network inverter technology experiment are tested, additionally it is possible to some expansion experiments are completed, to provide the sun of higher level Energy correlational study, such as on-site supervision solar electrical energy generation situation, simulate shadow occlusion phenomenon, spottiness etc., and can use Wireless transmission method is sent to high in the clouds platform the related data of experiment, so that the data analysiss in later stage are used；This utility model The experiment content of correlation is realized using good man-machine interaction mode, and this utility model can change photovoltaic in software end The group string structure of component；This utility model portable light overhead utility analog meter, can not only interior use analog light source, additionally it is possible to Work in outdoor 24 hours is easily moved to the power generation situation of fully simulated true electric station.And these designs are all by very big side Just related scientific research librarian use.It is low cost, a workable portable light overhead utility mould by large-sized photovoltaic power station micro Intend instrument, and the designs such as corresponding power station operational factor, the collection of environmental information, process, transmission storage are added into Midget plant, be this One spotlight of utility model, while being also a major challenge of this utility model design.

The content of the invention

This utility model purpose is to be difficult to test for existing large-sized photovoltaic power station, and conventional photovoltaic power station instruments used for education are difficult To simulate the situation of true power station operation, a kind of portable light overhead utility analog meter is devised.

This utility model includes being arranged on instrument viewing area, man-machine interaction region, the function control on device body surface Region, puts data processing in device body and control module, some photovoltaic information acquisition modules, DC/DC control modules, inverse Become module, energy-storage units (as accumulator battery), different loads unit, for receiving present apparatus present position environmental data Environmental data collecting module, and the side wing being flexibly connected with device body, and the side wing front is placed with photovoltaic module Array；
