Abstract
Disclosed is a power generation system using solar batteries to generate electricity and applicable to chips. Solar battery packs connected in series charge a storage battery pack of which the series voltage is higher than 192V and lower than 300V. Charge and discharge are controlled by a 'charging and inverting combination machine'. The quality of battery charge and discharge is guaranteed by an equalizer. The rated output voltage of the storage battery pack is inverted into three-phase 220V voltage to power electric equipment. An electric line evenly distributes load through three wires.
Description
Affiliated technical field
The present invention is that one is utilized solar cell power generation, and to charge in batteries, convert the marine generating plant of three-phase 220V alternating current to by " charging inversion unit mahine ", by the electricity generation system of this installation composition, provide daily life electricity consumption to boats and ships, can significantly save the fuel cost of generator powered, reduce noise, have obvious practicality, saving, effect easily.
Background technology
No matter be boats and ships oceans, or inland water transport, the household electricity on ship, be all generally taking generator generating as main, not only consume a large amount of fuel oils, in generating, also produce very strong noise, environment is produced to very large pollution, to ship's staff's health also causing damage in various degree.
Solar power generation is the best method that solves boats and ships electricity consumption, not only directly saves fuel cost, more reduces waste discharge, and noiselessness disturbs.
The present invention be directed to the actual conditions of ship household electricity, according to the design feature of ship, be combined into take up an area that little, power is large, handled easily, be convenient to install, low solar power system self consumes energy, particularly high voltage impulse electricity, reduce cable diameter and facilitated and install and use, be conducive to solar energy utilization and universal.
Summary of the invention
The present invention is: use solar battery group, " charging inversion unit mahine ", batteries etc., through connecting, become and be applicable to the electricity generation system that ship uses; When using 8 nominal 35V solar modules, the charging voltage that composition series connection group is 240V to 280V, to the storage battery series connection group charging of 96 2V1000Ah, the series voltage of batteries is 192V; When using 16 nominal 35 solar modules, form the charging voltage that each series connection group is 400V to 450V, to the storage battery series connection group charging of 150 2V1000Ah, or the storage battery series connection group of 25 12V200Ah is charged, the series voltage of batteries is 300V, by " charging inversion unit mahine ", become the alternating current of 3 line three-phase 220V to charge in batteries inversion, provide electric power to power consumption equipment on ship.
The technical scheme that the present invention adopts in the time solving its technical problem is: adopting the solar battery group of series connection to battery charging more than series voltage 192V, is to discharge and recharge control by " charging inversion unit mahine "; Because solar cell and storage battery are series voltages, in the time providing electric power to " charging inversion unit mahine ", than using traditional 48V DC low-voltage inverter power supply mode, can reduce corresponding multiple electric current, the present embodiment is: one of " the charging inversion unit mahine " of three-phase 220V10 kw of power; Solar cell is 35V250W40 piece 10KW altogether, is made up of 5 series connection groups; 48,12V200Ah storage battery, formed by 3 battery pack, the maximum charging current of solar cell is 40A, batteries is 52A to " charging inversion unit mahine " supply current 10 kilowatt hours, be to use 1/4th of traditional 48V inverter power supply 10 kilowatt hour electric currents, while therefore native system being installed, reduce 3/4ths than the sectional area that traditional 48V inverters stube cable is installed, not only save installation cost, the difficulty of the poling cabling while also having reduced installing cables on ship and operation intensity.Become more simple owing to using " charging inversion unit mahine " to make to install, make whole system be more convenient for implementing and safeguarding.
The supporting circuit of the present invention carries out balance distribution to power, and reasonable distribution load between three lines, because distribution wire diameter is less, is therefore installed and is simply convenient to general electrician's operation, facilitates routine use and maintenance.
