Description
Technical field
The utility model relates to monitoring technology field, in particular to a kind of distributed energy power stations number based on MQTT agreement
According to acquisition system.
Background technique
Currently, the energy is the basic motive of national economy.In severe energy substitution situation and human ecological environment (weather
Warm) pressure under, countries in the world all using developing and using sustainable clean energy resource as the energy development strategy in future, wherein
Solar energy with it is resourceful, one of there is no a particular advantages such as region boundary line, cleaning and become hot spot concerned by people.Solar energy
Volt power generation is a kind of forms of electricity generation that solar radiant energy is converted directly into electric energy using the photovoltaic effect principle of solar cell.
As one of fastest-rising new high-tech industry in the world since the 1980s, solar energy power generating
Industry and market are rapidly developed under the promotion of the strength of lasting technological progress and the law & policy of gradual perfection.By
The fast development in more than ten years, China's photovoltaic industry have entered the large-scale development stage.Cut-off 2013, the accumulative installation of China's photovoltaic
Amount is 17.16GW, and newly-increased photovoltaic installation amount target is 14GW within 2014, and the year two thousand twenty photovoltaic power generation total capacity will reach 180GW.
The operation level of photovoltaic generating system is the key element for influencing system benefit, it will directly affect photovoltaic power generation system
Operation expense, generating efficiency and the generating reliability of system, how the operation of safeguards system high level is each side's common concern
The problem of.
However so huge large-scale photovoltaic generating system, number of devices is huge, when some device fails, to institute
There is equipment all to check that workload is very huge one by one.By taking one 50,000 kilowatts of photovoltaic plant as an example, inverter have more than 100,
More than 800 of header box, battery component are more than 190,000 pieces, also large number of direct current confluence branch, in addition current photovoltaic power generation
System distribution or remote geographic location are had inconvenient traffic or are built in building roof, and equipment routing inspection and management are extremely difficult.
Since photovoltaic industry is many compared with thermoelectricity starting evening, informatization is just carried out, especially with operation power station
Increase, if only by manually report, the mode of artificial collect statistics, operations staff's workload certainly will be increased, and in people
Inevitably there is mistake during work collect statistics, cause data inaccuracy, not in time, the fault of production decision certainly will be caused.
How to realize scientific management, improve generated energy, extend the power generation service life, is asking for power station owner and grid company institute's common concern
Topic.
Also have at present for the problem that the data acquisition of photovoltaic generating system and monitoring system, but it exists and has: 1) monitoring
Data can not adopt, is insincere.It does not organize string monitoring or there was only simple group string data acquisition, monitoring measurement accuracy is not high, measures
Data inaccuracy；2) monitoring data reports difficulty.Monitoring data is uploaded by RS-485 bus, and transmission rate is low, communication failure
It is more, accidentally alert and to fail to report situation serious；3) fault location is difficult.Photovoltaic module and number of nodes are huge, lack effective failure
Positioning means, fault detection are compared mainly by manual inspection, by multimeter hand dipping, and the troubleshooting period is long, influences hair
Electric output, maintenance efficiency is low, investment manpower is big；4) system administration lacks digitlization means.Monitoring information is simply acquired and is presented,
Mass data report is handled by hand by Excel, and aggregation of data analysis ability is poor, and generate electricity performance analysis and improvement shortage quantization hand
Section cannot achieve multisystem unified management.
Therefore, the application technologies such as computer, modern communication means and intelligent mobile handheld terminal how are efficiently used, it is quasi-
The each photovoltaic plant day-to-day operation data of acknowledgement collection, and secondary calculating is carried out as needed, then data are reported into corporate HQ,
For subsequent statistical analysis, foundation is provided for production decision, while mitigating operations staff's workload to become we to be solved one
A project.Information-based photovoltaic plant operation management system can improve power station integrated efficiency and generated energy；Photovoltaic electric can also be saved
The cost of investment stood is conducive to photovoltaic plant standardized operation, maintenance and technical standard, improves production photovoltaic plant operation and management
It is horizontal；And it is able to achieve data mining and analysis, it is the basic data of the specific works plan of decision and department.
If can carry out comprehensive no dead angle to power station by intelligent solution and check and accept, it is ensured that construction quality
And equipment performance is up to standard.Intelligent solution can in time alarm to equipment fault, especially examine a group tandem failure
Disconnected, relative to sampling observation, not only efficiently, and fault detection covers entire power station；It is calculated by the dispersion ratio of inverter and component,
The overall operation that power station inverter and battery pack string can be measured is horizontal, and to the comprehensive monitoring in power station in addition to checking and accepting
Shi Qi is essential after coming into operation.
