Description
Technical field
The present invention relates to the solar photovoltaic generation system technical field, particularly a kind of photovoltaic generating system.
Background technology
In the past, photovoltaic generation was mainly used in space generating and items application technology, like calculator.After 2000, photovoltaic generation also begins trend and is incorporated into the power networks more on a large scale and off-grid photovoltaic generation application, like the photovoltaic system of large scale business power station and architecture-integral.Solar photovoltaic generation system partly is made up of photovoltaic module, inverter and photovoltaic fixed system such as support etc.It is photovoltaic module that solar energy photovoltaic system produces the most crucial unit of electric power.Present photovoltaic module can be divided into two simple parts: power generation part and wiring part.Power generation part is made up of photovoltaic cell and encapsulating material.Here, photovoltaic cell can be a crystal silicon cell, also can be hull cell.The wiring part is made up of terminal box that has bypass diode and cable terminal.Bypass diode can be in assembly photovoltaic cell work this its short-circuit protection is fallen when undesired, thereby avoid security incidents such as fire.In recent years, add intelligent factor, be used to handle that voltage, electric current between photovoltaic system assembly and the assembly do not match etc., to improve the actual power amount of photovoltaic system at the assembly end.
According to the relevant laws rules and regulations of national Electrical Safety, human body the safe voltage that can directly touch be 36V, safe current is 0.1A.Under the dry situation, human body resistance: 1000～3000 Ω; Under the moist situation, human body resistance: 500～800 Ω.When the electric current of human body, can cause the sensation of human body fiber crops thorn through 0.6mA; Electric current through the 20mA peace will cause severe pain and expiratory dyspnea; Electric current through the 50mA peace just is in peril of one's life; Through the above electric current of 100mA peace, just can cause that heart paralysis, atrium stop to beat, until death.
In conjunction with above standard, first we consider the potential safety hazard of solar power system from battery, three levels of assembly and system to human body.The first, solar cell.In the system, the generator unit of the fundamental sum bottom is discrete solar cell.The supply power voltage of the solar cell of single PN junction is about 0.6-0.7V, and supply current is about 0.030-0.038A/cm2.For the monocrystaline silicon solar cell of the common nearly square of 125x125mm2, the available electric current of monolithic battery is about 4.5-5.5A.For the square polycrystalline silicon solar cell of common 156x156mm2, the available electric current of monolithic battery is about 7-8A.The second, assembly.The operating voltage of photovoltaic module is generally 35-45V at present, and operating current is generally 4-8A.The lifting of voltage mainly is to reach through 60 or above battery sheet are together in series in the assembly.Three, photovoltaic system.In the photovoltaic system of actual power, again several component string parallel connections are promoted real work voltage, reach 200V, 400V even higher.Along with further developing of solar energy generation technology, the voltage and current characteristic of basic generator unit battery can further increase substantially.For example the more piece stack technology can promote the voltage of single battery more than 2-3 times.The operating current that for example electroplate, laser doping technology and back side battery technology etc. can increase substantially battery is more than 10% or the like.These technological progresses will reduce the cost of photovoltaic generation significantly, but also will bring bigger threat to the security consideration of photovoltaic generating system simultaneously.
Secondly, when considering the safety problem of photovoltaic generating system, we it should be noted that the distributivity of photovoltaic generation.Very different on this point with conventional electric power (like firepower, hydroelectric power generation).Separate the generating of conventional electric power, transmission and place to use, is convenient to centralized control.And photovoltaic generation has very large distributivity.For example, on Application in Building, photovoltaic cell is distributed in the roof widely.In the application of automobile and yacht, photovoltaic cell extensively is distributed in places such as roof, yacht top.These are local directly approaching with the human body that uses photovoltaic electric power.And just because of the distributivity of photovoltaic generation, only to ground connection such as the frame of photovoltaic module or bracing frame can not be effectively resolution system safety problem fully.
In addition, photovoltaic generation is different to the mechanism that human body damages with common electricity generation system.This is also greatly to having increased the safety design requirement of photovoltaic generating system.The interface that normal conventional electric power uses insulating material such as multi-layer soft plastic cement to come transferring electric power or draw as electric power usually.The mechanism of therefore, getting an electric shock usually is skin contact electrification end.The resistance of skin is far longer than human body fluid.Though the very low 0.05～0.2mm of the outermost cuticula thickness of human body skin epidermis, resistivity is up to 0.1～1M Ω m.And photovoltaic generating system also possibly directly produce electric shock through human body fluid except above-mentioned mechanism, and the resistivity of human body fluid can be 1-15 Ω m even lower.Attempt the example of a roof, the situation on roof, yacht top or the like is similar, when roof breaks under special circumstances; Charged battery sheet, or its encapsulating material such as glass are if scratch skin; And directly touch the human body fluid of strong conductivity, thereby cause serious human injury more easily.
Four, photovoltaic generation safety must be paid close attention to the safe current problem.Photovoltaic cell capable of generating power have low-voltage (～0.6V) with the characteristics of big electric current (1A-6A).This dot characteristics is different fully with common daily alternating current.Accompanying drawing two has provided the simple physical principle model figure of electrical security consideration.The generating subelement is composed in series by a battery sheet or several battery sheet.Here be a current source with its equivalence, the internal resistance rs of a series connection and a parallel resistor rsh.A part of equivalence of human body or human body is a parallel resistor R.This schematic diagram provides a kind of method of simple estimation safe voltage.If the voltage through human body, electric current are simultaneously less than safe voltage (36V) and safe current (50mA), then system is safe.Below we estimate with an instance.Photovoltaic generating system shown in figure three, we investigate a generating subelement, the battery strings that it is made up of 6 batteries.Rated voltage under each photovoltaic cell standard state and electric current are 0.6V and 1A, rs=0.003ohm, rsh=20ohm.This battery strings can equivalence be the equivalent electric circuit of figure two.
Consider special circumstances, when human body was hurt by glass, electric current directly contacted human body fluid, and human body resistance is 200ohm.Total voltage is 3.6V, and Rs can ignore.All-in resistance is the resistance after rsh=20ohm and the human body resistance 200ohm parallel connection, and numerical value is 18.2ohm, and total current is 198mA, and the electric current that flows through human body is 18mA.This electric current can let the algesiogenic sensation of people, but human body safety.In addition, consider the generating subelement of 36 battery strings, total voltage is 21.6V; Rs can ignore, and all-in resistance is the resistance after rsh=20ohm and the human body resistance 200ohm parallel connection, and numerical value is 18.2ohm; Total current is 1187mA, and the electric current that flows through human body is 108mA.This electric current is through heart, and consequently the people desperately.
Summary of the invention
