Description
Technical field
The present invention relates to a kind of naval electric systems and method of supplying power to thereof, belong to Circuits System applied technical field.
Background technology
Various naval vessels (include carry internal combustion engine submarine, hereafter referred to collectively as naval vessel) have become as the daily traffic of people,
Transport and national defence important equipment, such as manned various yachts and passenger boat, the cargo ship of transport goods, various law enforcement ship, naval
Various naval vessels, even carry the submarine etc. of internal combustion engine.Electrical system is the requisite part in naval vessel, naval vessel conventional electrical system
System is as it is shown in figure 1, be mainly made up of naval vessel set generator, voltage regulator, accumulator etc., and electrical equipment is according to power characteristic master
Being divided into and need transient state powerful startup motor and continue other naval vessels low power to carry power device, naval vessel accumulator is to supply
One of electricity requisite power supply of system, powers to startup motor when the internal combustion engine start on naval vessel；Electromotor does not works or sends out
When motivation works under the highest rotating speed, accumulator is powered to naval vessel power consumer apparatus；Its generating dress is exceeded at power consumer apparatus power
When putting power, accumulator is powered to power consumer apparatus with generator combined.Accumulator in naval vessel should be responsible for providing naval vessel to carry and use
Electric installation (as instrument show, program self-inspection, the low-power device such as glittering, sound equipment short-term operation of signal lights) energy, again
Being responsible for providing engine start moment powerful energy, in operative practice, this scheme exposes problems with:
1. start system electrical characteristics different with other power device and accumulator property is required widely different: start system
Require that battery discharging high rate performance is excellent, other power consumer apparatus then require accumulator possess certain capacity can, the most forthright
Can be less demanding, this situation causes accumulator to be that the transient state needed for meeting engine cold-start is high-power, it has to " excess is joined
Put ", make battery the biggest but also heavy, cause the wasting of resources, nor economical.
2. external when using under the electric equipment in use naval vessel long-time under marine engine flameout state, flameout state
Forget after power-supply device, tail-off to turn off the light etc. situation time, discharged or defective battery will be caused cannot to complete marine engine
Next time starts, when there is this situation, it has to changes battery or uses emergency power supply to help to start.
3. marine engine cold start-up electric current is relatively big, relatively big to the rush of current of lead-acid accumulator, causes positive plate activity
Material comes off so that lead-acid battery pool-size declines very fast, service life shorter (generally 2～3 years), changes more frequent,
Increase subscriber equipment maintenance workload and use cost；During naval vessel accumulator uses, due to user of service or attendant
Cannot accurately confirm that accumulator uses state, generally using naval vessel the phenomenon that has some setbacks of starting afterwards overnight as the judgement life of storage battery
The standard of termination rather than cannot electric power storage or cannot the power consumer apparatus electricity consumption of regular supply naval vessel scrap as accumulator using accumulator
Standard, causes accumulator " to be sentenced useless too early ".
4., when marine engine starts (particularly cold start-up), accumulator instantaneous voltage drop is relatively big, causes naval vessel voltage quick
Sense equipment (computer system, programmable logic controller (PLC), electronic equipment etc.) cannot normally work, and easily occurs that computer is disorderly
The faults such as unrest, loss of data and equipment are out of service, even cause the accidental damage of warship ship-borne equipment time serious.
To this end, it has been proposed that accumulator two ends parallel connection super capacitor mode jointly be start motor power, although
This scheme extends the service life of accumulator to a certain extent, but accumulator is also intended to undertake power-type power unit
Startup task, the most fundamentally not solving accumulator is that power-type power unit is powered and caused impacting battery current
Greatly, the problems such as life of storage battery reduction are caused；And owing to accumulator and power-type power unit voltage " clamp " problem, this
Improve the most limited to the improvement of internal combustion engine starting problem.
Summary of the invention
It is an object of the invention to a kind of naval electric systems and method of supplying power to thereof, with solve to use at present energy unit come for
Internal combustion engine start motor power supply station causes energy unit power requirement higher, internal combustion engine start weak effect, energy unit " excess
Configuration " and be vulnerable to heavy current impact and affect the problems such as life-span.
The present invention solves that above-mentioned technical problem provides a kind of naval electric systems, including starting motor, naval vessel load

Described power cell be ultracapacitor monomer, by ultracapacitor monomer connection in series-parallel composition module or
Array of capacitors.
Present invention also offers the method for supplying power to of a kind of naval electric systems, the method by the electrical equipment on naval vessel according to merit
Rate characteristic makes a distinction, and is divided into power-type power unit and non-power type power unit, and power-type power unit is by power cell
Power supply, non-power type power unit powered by energy unit, between power cell and energy unit by isolation charhing unit every
From, when power-type power unit needs power supply, isolation charhing unit disconnect the electrical connection of power cell and energy unit,
Be that power-type power unit is powered only with power cell, power cell electricity less than setting value time or power-type power unit
Before work, power cell isolation charhing unit control under by energy unit or external power charging, described energy list
Unit is energy storage device, and described power cell is the energy storage device of high-multiplying power discharge.

The invention has the beneficial effects as follows: naval electric systems of the present invention uses combination type superbattery to provide electric energy, combination
Formula superbattery includes energy unit and power cell, connects and have isolation charging single between energy unit and power cell outfan
Unit, energy unit outfan carries power device for electrical connection naval vessel, and power cell outfan starts motor for electrical connection, and isolation is filled
Electric unit, for when energy unit or electromotor do not charge to power cell, disconnects power cell logical with the electric current of energy unit
Road, and for before the work of power-type power unit or during power cell electricity deficiency, for power cell charging.The present invention passes through
Powering for starting motor only with the power cell in combination type superbattery, solving and using accumulator at present is that power-type is used
Electric unit is powered and is caused accumulator " excess configuration ", big to battery current impact, causes life of storage battery reduction, other electricity consumption
Unit power shakiness etc. problem, prevent because of accumulator over-discharge cause start motor can not start, affect the normal work of internal combustion engine
Make, utilize power cell to undertake the high-power job task of transient state simultaneously, it is possible to increase start the service behaviour of motor.
Energy unit in the combination type superbattery that naval electric systems of the present invention is used no longer undertakes the big merit of transient state
Rate job task, the lasting energy supply of the most responsible low-power load, not damaged by heavy current impact, the life-span is longer, it is to avoid energy list
Unit is sentenced useless by " too early ", causes waste, and can " reduce weight " on type selection, it is achieved miniaturization, lightweight and Marine campaign system
The facilitation arranged；Only relying on power cell to start, the startability making internal combustion engine is more preferable, especially at low-temperature startup.
