Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further described in detail。
Fig. 1 is the structured flowchart of solar charging/discharging system of the present utility model。
Detailed description of the invention
As it is shown in figure 1, one end of solar panel connects voltage x current sampling unit, voltage x current sampling unit connects single-chip microcomputer by AD conversion unit, and single-chip microcomputer has pin to be connected with the grid of PMOS, separately has pin to select the control port of switch to be connected with power supply；The other end of solar panel is connected with PMOS by diode, and PMOS is connected with DC/DC changer；Marine storage battery selects switch to be connected with DC/DC changer, panel respectively by powering。Panel connects boats and ships main power source respectively to boats and ships low-voltage direct-current system and boats and ships main power source。
Its operation principle of the present utility model is, the output of solar panel carries out after voltage x current sampling through voltage x current sampling unit, then through after carrying out analog digital conversion by AD conversion unit, digital signal is fed back to single-chip microcomputer, single-chip microcomputer drives PMOS according to the working condition output pwm signal of solar panel, it is achieved the maximal power tracing to solar panels。DC/DC changer is used for realizing four stages to accumulator, and the charging including trickle charge, constant-current charge, constant-voltage charge, floating charge controls。
Meanwhile, solar charging/discharging system accesses ship electricity system by panel, poor when running into weather condition, when illumination is inadequate, switch automatic switchover can be selected to utilize boats and ships main power source to power to boats and ships low-voltage direct-current system by the power supply in system。
Embodiment
Adopting native system is accumulator charging, the charging current of full ship accumulator is 200A, average every flight number charges 1 time, charge 10h every time, and each power consumption of charger is 200A*24V*10h/0.9=53.3kWh (mean charging current is about 200A, and charger efficiency is about 0.9), i.e. 53.3 degree of electricity, the annual natural law that weather is good, illumination is sufficient, by 200 days, namely there are about the flight number of 55% and native system can be adopted to charge in 12 flight numbers, then annual power consumption is 351.8 degree。By often 1 yuan of calculating of degree electricity, then the expense charged a battery every year is 351.8 yuan。
Adopting native system is that full ship low-voltage equipment is powered, and the power of full ship DC24V electrical equipment is about 5kW, and boats and ships main power source needs the power of output to be about 5kW/0.9=5.6kW (0.9 is efficient energy conversion) per hour。In one flight number, DC24V electrical equipment on average uses about 6 days, i.e. power consumption 5.6kW*6*24h=806.4kWh in a flight number, and the annual spendable probability of native system is 200/365=0.55,
1 year power consumption 806.4kWh*12*0.55=5322.2kWh。Calculating with diesel generating set, the oil consumption of diesel generating set is about 200g/kW.h, then need to consume diesel oil 5322.2kWh*200g/kW.h=1064.4kg, add up to about 1252.2 liters。Marine diesel oil calculates with 5.5 yuan/liter, then need fuel cost 6887.1 yuan the whole year。
In sum: the seagoing vessel of about 500 tonnes adopts native system can save expense 7238.9 yuan every year。
China is shipbuilding ship big country, powers to boats and ships low-pressure system according to solar charging/discharging system, and its energy-saving effect is appreciable。
It should be noted last that, above detailed description of the invention is only in order to illustrate the technical solution of the utility model and unrestricted, although this utility model being described in detail with reference to preferred embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent replacement, without deviating from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model。
