Description
Technical field
The present invention relates to a kind of photovoltaic plant technology, and in particular to a kind of to use solar energy power generating impedance regulating
The grid-connected power station of novel photovoltaic.
Background technology
Conventional photovoltaic interconnection technology causes photovoltaic generation high cost inefficient despite potential resistance, and this is to State owned land
Resource and material resources cause greatly waste, while in harmonic wave flickering, inversion is cut off, high pressure earial drainage, low pressure off-the-line, public frequency are dirty
The hidden danger that cannot be excluded is left in terms of dye, such as thunderbolt event, the scene of low pressure off-the-line will for the high pressure earial drainage event that flickering causes
Be the sea of fire in flakes, this is more than ten years experience that uninterruptedly experiment repeats by a definite date, is not to infer the fable for sending without foundation, (if day
Jin Gang blast losses upper 10,000,000,000 are not also forgotten) for country and the safety of the whole people, we should not wait, and bigger the repeated performance of tragedy.
Solar photovoltaic generation system in solar photovoltaic grid-connection power station includes solar battery sheet, and which mainly includes crystalline substance
Body silion cell.Crystal silicon solar energy battery has series resistance and parallel resistance, and cell piece can simply regard such a as
Model：The source-series resistance of one constant current, a resistance in parallel；Wherein series resistance is usually by the electricity of positive silver-colored grid
The resistance of resistance, the resistance of silicon sheet material itself and aluminum back surface field causes.And parallel resistance does not actually have such a resistance,
As cell piece has leakage current, it is in opposite direction with cell piece output current, therefore can offset part output current, makes output
Current reduction, this is equivalent to a resistor coupled in parallel on a cell piece.
The grid-connected total installed capacity of China comes first of global total installed capacity, and more than 50GW, which produces per year statistics in 2015
More than 700,000,000,000, wherein 455,000,000,000 economic growth belong to bubble economy, we want to retrieve these huge virtual Jing for value estimation
Ji, we want the generation for avoiding major disaster, and it is grid-connected that every conventional art builds up, or demolition upgrading.
Scientific practice since over half a century, makes people gradually recognize the transformational relation between light and electricity, establishes
Light is exactly electric theory, therefore, people are now referred to as photovoltaic generation solar electrical energy generation.
The theoretical of electron transition proposes that, in the Soviet Union, silicon wafer battery is produced in the U.S., and technique perfect in workmanship is in Japan, equipment
Germany is matched with comprehensively, and an incision technology of China's photovoltaic industry chain is all that we do not have the knowledge of autonomous innovation from Germany's introduction
Property right, can only accompany behind other country, with cheap cheap product of working out, then international with the convention competition of price dumping
Society.
At the beginning of 2013, the investigational data of China Electric Power Research Institute's publicity, Tibet Yangbajing photovoltaic plant is most
It is high-power for per minute 75% flickering amplitude, indicate more than 70% reactive voltage flickering, cause oscillatory type operation
Vicious cycle, is a typical leading case to 50 hertz of frequency pollution of public electric wire net.
At the beginning of 2013, national grid runs the analog data of ladder decay to grid-connected electricity, and 140,000 yuan simultaneously per hour
The electric power of net, finally can only be sold away with 50,000 yuan of commodity value, and electrical network must be born by 90,000 yuan of profit and loss.So, photovoltaic
The grid-connected quality of power supply becomes a unsolved mystery, 1.15 yuan of the Qinghai Province's original/grid-connected electricity price of degree, provisional 20% valuation so far
Pay, Xinjiang, the grid-connected of Inner Mongol slowly do not allow access electrical network, and electricity power enterprise is it is thought that abandon light behavior.But nobody
In all fairness photovoltaic the present in made in China how huge bubble economy, and bank, enterprise, electrical network bundled, into
For the community of destiny
Grid-connected, due to 35.7% true efficiency, being doomed photovoltaic plant itself apparent energy can not exert oneself.China Zhejiang
Jiang Sheng has the self-built photovoltaic plant of the factory of many, but there is no one to be truly realized the case generated power for their own use, and can not all exert oneself
Void electricity and in national grid, oneself using rely on national grid supply.The universal grid-connected electric power of China, from quality
Speech, maximum go out only within 35.7%, illustrate that parallel network reverse has all been accomplished to the greatest extent to change very with vacation.So on, it is grid-connected
When public network accounts for 10% ratio, electrical network is held when daring not accept, and the significantly flickering of reactive voltage, inversion are cut off, high pressure earial drainage
The local of national grid certainly will be caused to paralyse.It is during the high pressure earial drainage of 35KV --- 600KV, as indicated in thunderbolt event, very harmful；
The scene of photovoltaic arrays off-the-line will be that a piece of company in the sea of fire is a piece of.This is the experience of uninterrupted test in 12 years, is not imagined
Fable.Spain is voluntarily dissolved in square formation automatic parallel off in 2005, welding stannum band, the demonstration project down techniques scheme of Japan
The more substantial equipment of electrical network infrastructure for unsuccessfully causing, the fact that these are all borne out by ironclad evidence authority.Chinese photovoltaic is centralized
Extensive example, runs counter to ohmage theorem pell-mell development despite potential resistance, endless potential safety hazard under hiding.In China
Carry forward vigorously town and country popularize photovoltaic generation important period, we must not have a bit fluke mind, should highly vigilant of it is outmoded
The disaster crisis of technology, because the safety problem of state's industrial development people's lives cannot be properly settled, related new industry
Also just normally cannot go in an orderly manner, if our process runs counter to scientific truth, subjective development will be in disaster
Fall back for history.Investigate forensic data below on the spot：

The power station is group string that confluxes with the 20 component series connection of 8.676A, 30V component, forms the electricity of 600V running voltages
Stand, effective work of actual normal operation peak power point value is 500V.Because the potential resistance of group string is exceeded, 16.66% is caused
Reactive voltage, the electricity that 20 megawatts of photovoltaic plant is sent per hour less is：20X1248AX100V=2496KW, myopia in
2500 degree of electricity are economical with regard to 2500 yuan of loss, and one-day loss is more than 10000 yuan.
Second case is collected evidence：Praise and contain solar energy diversion demonstration project in the Xinjiang of in August, 2014.
Installed capacity 10.56KW loads water pump 2.5KW, the batch (-type) mean effective power 840W of actual continuous operation, reason
Be 8% by the practical efficiency of installation because component lines its potential resistance in 5A, 550V is 110 Ω, severe overweight it is latent
Electric energy conservation is destroyed thoroughly in resistance, this diversion demonstration project is then a kind of step operation, the direct current before inverter
With alternating voltage after inverter, synchronous change liquid crystal display data (400V, 4V, 8V, 16V, 32V, 64V, 120V, 240V,
280V, 320V, 360V, 380V, 400V, 4V)/3 seconds, in 3 seconds one cycle period of oscillations, because empty electricity can not be exerted oneself water
When pump starts work every time, running voltage straight line more than photo-voltaic power supply 660V open-circuit voltages is dropped to into the area of 4V and 400V
Between, inversion is cut off automatically, and when moment electricity goes back up to original position, inverter starts again, suspends again, and repetitive cycling once is dodged within 3 seconds
Become, 50 hertz of public network frequency will be polluted by 10 hertz or so of impact.For 2.5KW water pumps, the alternating current of motor work
Pressure, the interval floating 99% fall change, and the speed that 3600 revs/min of motor is run at 1200 revs/min all the time, three/
Two power is damaged.
3rd evidence obtaining：In October, 2015, Zhejiang Yuhuan new technique conventional art contrast experiment.
This experiment case study is primarily used to witness grid-connected power quality problem, and it is with two same inverters
Make two electricity generation systems to be contrasted.
4 days 10 January in 2016:00——13:00 electric station grid connection operation electrical quantity document report (weather conditions are fine) is such as
Table 1 below：
Table 1：Electric station grid connection runs electrical quantity document report
Each species diversity that three above evidence obtaining case shows, is all the real authority of China's photovoltaic net, in such technology
Under background, the development of our blindnesses is exactly waste of resource, runs counter to natural law construction and is equal to manufacture disaster.
The empty electricity of photovoltaic is grid-connected once accounting for more than 10% proportion, the voltage of whole public network will be completely out of control, significantly
During flickering earial drainage, it is a piece of that the location of grid-connected connection reforms into the sea of fire.
