Background technology
Progress along with expanding economy, society; People propose increasingly high requirement to the energy; Seek new forms of energy and become the urgent problem that current mankind faces; And it is very huge to be radiated at tellurian solar energy, is radiated at tellurian solar energy, the consumption that just is enough to supply 1 year energy of global human in about 40 minutes.We can say that solar energy is really inexhaustible, the nexhaustible energy, and solar power generation is definitely clean, does not produce public hazards, is perfect energy sources so solar power generation is described as.
Obtain electric power from solar energy, need to carry out light-to-current inversion and realize through solar cell.It has following characteristics with other power supply electricity generating principles were different fully in the past: 1. do not have exhausted dangerous; 2. absolute clean (nuisanceless); 3. do not receive the restriction of resource distribution region; 4. can generate electricity nearby in electricity consumption place; 5. can source quality high; 6. the user is acceptant on the emotion; The time of 7. obtaining energy cost is short.Weak point is: 1. the Energy distribution density of irradiation is little, promptly will take huge area; 2. the same four seasons of the energy that obtain, reach and rain or shine wait meteorological condition relevant round the clock.But generally speaking, one flaw cannot mar the jade, and as new forms of energy, solar energy has very big advantage, therefore receives the attention of countries in the world.
When utilizing solar power generation, a plurality of optical-electric modules are electrically connected, optical-electric module electricity power are delivered to electrical network through one or more inverters.
Inverter is the equipment that direct current is converted to alternating current.Because solar cell and storage battery are DC power supplys, and load is when being AC load, and inverter is absolutely necessary.Inverter can be divided into independent operating inverter and combining inverter by operational mode.The independent operating inverter is used for the solar cell power generation system of independent operating, is independent electric.The solar cell power generation system that combining inverter is used to be incorporated into the power networks.Inverter can be divided into square-wave inverter and sinewave inverter by the output wave mode.The square-wave inverter circuit is simple, and cost is low, but harmonic component is big, generally is used for below several hectowatts and the system not high to harmonic requirement.The sinewave inverter cost is high, but goes for various loads.
Photovoltaic generating system is by solar cell array, batteries, and charging-discharging controller, inverter, AC power distribution cabinet/AC distribution panel, equipment such as solar tracking control system are formed.
What inverter was exported is AC signal, if but do not modulate, then signal transmission distance is not far, is subject to disturb, and the signal to noise ratio after cascade is amplified is easy to degenerate.
