Description
Technical field
The present invention relates to a kind of photovoltaic generating system direct current arc fault induction type Cascaded amplification detection devices, belong to photovoltaic
Technical field of power generation.
Background technique
With the large-scale application of photovoltaic power generation, a lot of photovoltaic system event of fire occur successively for the ground such as America and Europe, cause one
Fixed economic loss all points to DC terminal fault electric arc to the reason of this kind of accident investigation discovery most electrical fires afterwards.With
Photovoltaic plant put into operation time limit increase, electronic component aging, cable rupture, contact loosens or animal grabs and the reasons such as stings all
Fault electric arc, and the installation of most of photovoltaic arrays may be caused, what is utilized is all long string of high-voltage dc power supply, is also increased
Related with electric arc safety problem.Can only be to overcurrent, short circuit in view of protective devices such as current fuse, breakers situations such as
It is protected, it is helpless to the detection of this kind of fault electric arc.It realizes and distribution loop is quickly and effectively protected, taking into account prevents
Malfunction, breaking arc faulty line do not influence the normal work of equipment simultaneously it is necessary to timely and effectively carry out to fault electric arc
Detection.Existing series fault arc recognition methods is broadly divided into two classes.One kind is arc light, the arc generated by fault electric arc
The non-electrical signals such as sound, temperature parameter carries out identification judgement, but fault electric arc generation point is uncertain in actual route or equipment,
Identification has difficulties；Another kind of is that identification judgement is carried out with electrical parameters such as the voltage of fault electric arc, electric currents, and such method is mainly
Generated voltage, Current Waveform Characteristics are compared with normal voltage Current Waveform Characteristics and sentence when analysis generation arc fault
Disconnected, the limitation in the not examined place of this method, synchronous signal sample rate current is relatively simple, is current main direction of studying.Someone
Fault electric arc feature is analyzed using Fourier transform principle, although Fourier transformation can preferably reflect the overall situation of periodic signal
Feature, but it is weaker to analyze signal local feature ability.It, should by the arc energy variation in each wave band of wavelet transformation quantitative analysis
Method is obtained by analyze to the electric arc that broken down in time-frequency domain.But due to different in practice
Electrical equipment characteristic, can not predict fault electric arc generation and generation position is random, and influence factor is more, and the threshold value of each characteristic quantity is very
Difficulty defines, therefore the most Detection accuracy of these methods is low, False Rate is high.Therefore how to pass through different positions in acquisition photovoltaic system
The delta data of each current characteristic number when arc fault occurs is set, extracting time-frequency domain can be used as multiple characteristic quantities of criterion, root
Obtain the corresponding detection threshold value of each characteristic according to experimental analysis, by set time-frequency domain detection threshold value method detect arc fault at
For a great problem urgently to be solved, thus photovoltaic generating system direct current arc fault induction type Cascaded amplification detection device using therefore
Barrier detector induction photovoltaic generating system direct current arc fault is simultaneously transferred out fault message by data line, fault detection
Head be located at solar panel side, can under the drive of fault detection head motor solar panel upper surface back and forth
It is mobile, in moving process, according to electrostatic induction principle, the solar energy plate conductor wire of the normal solar energy plate for exporting electric energy by
Under the connection closed circuit electromagnetic radiation head of live wire, energized state, the closed circuit electromagnetic radiation capitiform of electric wire will be felt at electrostatic induction
The charge of metal plate is answered to redistribute, xenogenesis charge is attracted to induction metal plate, and like charges are ostracised to the another of conductor
End, i.e., at selecting chain switch, selecting chain switch is the identical copper sheet of two sizes, is made after having selecting chain switch slide-bar to run through
It is slided on selecting chain switch slide-bar for the sliding axle of selecting chain switch for selecting chain switch, so, in selecting chain
In the case that two copper sheets of switch have like charges, the repulsion that like charges generate divides two copper sheets of selecting chain switch
It opens, the circuit where malfunction indicator lamp is disconnected, therefore malfunction indicator lamp does not shine, still, if some solar energy plate occurs
Failure, then selecting chain switchs the power that just do not repel each other, thus under the supporting role of selecting chain switch branch piece, mutual exclusion
Two copper sheets of circuit switch are then close to each other, and the circuit where malfunction indicator lamp is closed, and malfunction indicator lamp shines, to refer to
Show occur failure at this, fault condition is integrated in information and is integrated in cabin and Cascaded amplification, is led later by fault detection head
Line, data line and data the end of a thread are transferred out, and make operator manual or instrument is automatically handled failure, to reach
The purpose that the detection of induction type Cascaded amplification is carried out to photovoltaic generating system direct current arc fault, it is straight to invent a kind of photovoltaic generating system
Stream arc fault induction type Cascaded amplification detection device is necessary.
Summary of the invention
Each current characteristic number when in order to how overcome by acquiring different location generation arc fault in photovoltaic system
Delta data, extracting time-frequency domain can be used as multiple characteristic quantities of criterion, obtain the corresponding detection threshold of each characteristic according to experimental analysis
Value detects the problem of arc fault by the method for setting time-frequency domain detection threshold value, and it is straight that the present invention provides photovoltaic generating systems
