Background technology
Boats and ships are one of most important transport facilitys.Just as known, traditional boats and ships mainly are to rely on heat engine, drive such as diesel engine, steam turbine and gas turbine etc., the energy source of vessel motion depends on the non-renewable fuel oil with pollution, and this boats and ships take fuel oil as power resources have following remarkable defective:
1, waste gas, the waste water of discharging are more, and environmental pollution is more serious.
2, noise emission is very serious, and it is relatively low to take environmental amenity.
3, the consumption of the energy is larger, and the operation economy is relatively poor.Particularly in recent years, because the fuel price rise is too fast, the exercitor bears larger operation cost pressure.
In the face of more strict emission request, and improve the economic benefit of shipping transport and in order to satisfy the specific (special) requirements of special boat, people seek to solve the problems referred to above by the energy source and the propulsion mode that change boats and ships, and the electric propulsion mode then is an effective way.
For this reason, people have developed some electric ships, and some of them attempt utilizing new forms of energy.The structure of this class electric ship is substantially similar, it produces electric energy by solar panel, aerogenerator etc., store energy in the storage battery, and the dc inverter that will be stored in the battery by the DC/AC inverter becomes alternating current, for the AC load such as the illumination on the electric propulsion apparatus such as slurry, rudder and drive motor and the ship, air-conditioning provide AC energy.Yet.Although this class electric ship has adopted the new energy technologies such as wind energy, solar power, but because its storage battery output is direct current (DC), to give marine propulsion and AC load power supply, must be through the DC/AC conversion, certainly exist waste of power in the conversion process of energy, so that the electric energy of battery is not fully utilized, cause course continuation mileage shorter, be unfavorable for promoting.Also because the frequent start-stop of boats and ships, when starting, marine propulsion power supply power change is large, and from the operating characteristic of battery, the heavy current impact of variation will have a strong impact on the life-span of battery, so that battery altering is frequent, thereby cause maintenance cost to improve.With regard to battery technology, general single battery voltage very low (a few volt), and electric power system voltage peculiar to vessel can be up to several hectovolts needs the multiple batteries use that is cascaded.Because the internal resistance of each battery is isoparametric inconsistent, through after the charge and discharge repeatedly, the parameters such as the voltage of each battery can be inconsistent, and cell pressure is direct corresponding capacity of cell, the difference of cell pressure means that the capacity of battery is not fully utilized, thereby causes the off-capacity of whole battery, and course continuation mileage shortens, and battery also can affect the life-span of battery for a long time at operating on low voltage.In addition, if adopt novel lithium ion battery, also need temperature and the voltage parameter of each battery are sampled, if voltage below level directly causes battery failure easily, if voltage or excess Temperature can set off an explosion, the danger such as fire.Therefore need to monitor and manage it, with safety, the reliability of assurance battery energy storage cell operation, and prolong battery.
On the other hand, for the electric ship that adopts AC transmission, because its propulsion system power of motor is generally larger, when start-stop and motor-driven power change, serious to the harmonic pollution of the alternating current of whole ship.In addition, in the electric ship load, the overwhelming majority is the inductive load motor, so the AC power factor is very low, and AC transmission efficient is low, and reactive loss is serious, and is also poor to other AC load power supply qualities of power supply peculiar to vessel in addition.
