Description
Technical field
The present invention relates to a kind of distributed power source and its micro-capacitance sensor intelligent early-warning method, the technology for belonging to power industry is led
Domain.
Background technology
With global carbon dioxide displacement control and emission reduction, clean energy resource and new energy become global research and application and opened
Heat generating spot.In China, in order to promote clean energy resource and new energy development and application, a series of encouragement policies, photovoltaic, wind have been put into effect
Electric equal distribution generates electricity and is gradually taken seriously, and with the development of photo-voltaic power supply and wind electricity generation technology and perfect, has been in
Existing eruption type development.Photovoltaic generation is such as distributed, photovoltaic generation dress can be installed from factory, office, school, or even resident roof
Put, the wherein distributed power generation of small-scale can be directly accessed terminal power grid using 220 or 380V, and fairly large photovoltaic
It is then that can form microgrid with multiple distribution powers of 10kV or more grades access power network, 10kV or more grade to generate electricity, both
It can be incorporated into the power networks, can also isolated power grid.Consider from input and output ratio, micro-capacitance sensor is photovoltaic and wind-powered electricity generation distribution from now on
The main direction of development of power supply, microgrid not only greatly meet different social demands, while improve the flexibility of electricity consumption again.
If 10kV is directly accessed into power network, because 10kV circuits overlay area area is big, circuit handle rate is high, with distribution
The increase of formula power supply, after the distributed power source on every circuit reaches certain capacity, it can not only influence the voltage and transformation of circuit
Device capacity parameter, and make protection complex system, or even directly affect safe operation of electric network.In addition, with microgrid inside points
Cloth number of power sources increases and variation, various factors cross one another influences, it is necessary to using unified and intellectualized management system, comes in fact
The optimization of existing generation assets, while be monitored to running status and equipment health and safety, make microgrid all the time in safety and
Reliable running status, maximize economic, society and environmental benefit.The operational management of 10kV microgrids faces work great challenge,
This requires the automation and intellectuality that improve power transmission and transformation, by the on-line monitoring of 10kV microgrids, control, analysis and early warning etc.
To implement, so that it is guaranteed that the safe operation of power network.Even if 10kV microgrids are carried out into isolated power grid, its stability and security are also extremely
Close important.The distribution of 10kV ratings above generates electricity, and there is also same problem.
At home, there is no unified cut-in method and standard for photovoltaic distributed power generation at present.It is directed to small-scale
220V or 380V grades, grid-connected relatively easy, Application No. ZL201410643921X patent of invention and Patent No.
ZL2014206815675 utility model patent provide a kind of installation addressing flexibly, access is quick and convenient, safe and reliable, exempts from
Safeguard, the grid-connected Intelligent black box of distributed photovoltaic power generation that independence is strong and intelligence degree is high, the patent particularly solves
The grid-connected problem of 220 and 380V distributed photovoltaic power generations, but networking is generated electricity to grid stability and security without solving distribution
Influence problem.It is and most using common 10kV distributions switch cubicle, looped network for fairly large 10kV and above distributed power generation
Cabinet, the deficiency of these access devices are embodied in：1) traditional switch cubicle only has access function；2) equipment volume is huge, transport
Difficulty, installation workload is big, long construction period；3) it is simple that data are uploaded, only upload the electric parameters such as generated energy；4) will to environment
Height is sought, it is necessary to periodic maintenance；5) security, stability and reliability are low.It is noted that the distributed hair of 10kV ratings above
Influence of the electricity to power network is bigger, and wind-powered electricity generation distribution power also has the problem of similar.
Abroad, on March 20th, 2015, there is a total solar eclipse, European power transmission network alliance and ENTSO-E and moral in Europe
State's power network is all contributed to total solar eclipse same day photovoltaic and has carried out Accurate Prediction.Actual change and the prediction song a few days ago of contributing of total solar eclipse photovoltaic
The line goodness of fit is preferable, and photovoltaic output rate of change doubles than normal operation during total solar eclipse.Foot is prepared in advance
Enough spare capacities, it successfully avoid influence of the photovoltaic fluctuation to power grid security.As can be seen here, photovoltaic distributed power generation is by the external world
Condition influence is very big, so as to further influence electric power netting safe running.
In a word, for 10kV and ratings above distributed power source and its micro-capacitance sensor, current domestic not only access technology and dress
Backwardness is put, and lacks distributed power source and its micro-capacitance sensor intelligent early-warning device.
