Description
Technical field
The present invention relates to a kind of internal combustion engine generator electrical system and method for supplying power to thereof, belong to Circuits System application technology neck
Territory.
Background technology
Internal combustion engine generator is the gen-set with internal combustion engine as power, by internal combustion thermal unit, reciprocable generator list
Unit and supervision control unit composition, various internal combustion engine generators have become as the important production of the daily emergency service of people, life
Equipment, the mountain area remote especially for some or isolated island, owing to cannot set up electrical network, oil-electric engine becomes
Its main power supply facilities.And the electrical system requisite part that is internal combustion engine generator, internal combustion engine generator conventional electrical system
System is as it is shown in figure 1, be mainly made up of the electromotor on internal combustion engine generator, voltage regulator, accumulator etc., and electrical equipment is according to merit
Rate characteristic is broadly divided into be needed transient state powerful startup motor and continues to use Denso on other internal combustion engine generators low power
Putting, internal combustion engine generator accumulator is one of requisite power supply of electric power system, when the internal combustion engine start of internal combustion engine generator to
Start motor to power；When electromotor does not works or electromotor works under the highest rotating speed, accumulator is to internal combustion engine generator power consumption
Device is powered；When power consumer apparatus power exceedes its TRT power, accumulator is powered to power consumer apparatus with generator combined.
Power device that accumulator in internal combustion engine generator should be responsible for providing on internal combustion engine generator (as instrument show, program self-inspection, letter
The low-power devices such as glittering, the sound equipment short-term operation of signal lamp) energy, again be responsible for provide engine start moment powerful
Energy, in operative practice, this scheme exposes problems with:
1. internal combustion engine generator starts system electrical characteristics different with other power consumer apparatus to accumulator property requirement difference very
Big: starting system requirements battery discharging high rate performance excellent, other power consumer apparatus then requires that accumulator possesses certain capacity
Can, high rate performance less demanding.This situation causes accumulator to be that the transient state needed for meeting internal combustion engine cold start-up is high-power, no
Obtain not " excess configuration ", make battery the biggest but also heavy, nor economical.
2., when the abnormal use of internal combustion engine generator, use on internal combustion engine generator as long-time under internal combustion engine flameout state
Use external power supply equipment etc. under electric equipment, flameout state, discharged or defective battery will be caused cannot to complete internal combustion engine generator
Next time starts.
3. internal combustion engine generator 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 internal combustion engine generator accumulator uses, due to user of service or dimension
The personnel of protecting cannot accurately confirm that accumulator uses state, generally using the internal combustion engine generator phenomenon having some setbacks that starts afterwards overnight as sentencing
Determine life of storage battery termination standard rather than cannot electric power storage or cannot regular supply internal combustion engine generator power consumer apparatus with accumulator
Electricity consumption, as accumulator Rejection standard, causes accumulator " to be sentenced useless too early ".
4., when internal combustion engine generator starts (particularly cold start-up), accumulator instantaneous voltage drop is relatively big, causes internal combustion engine generator
Voltage sensitive equipment (computer system, programmable logic controller (PLC), electronic equipment etc.) cannot normally work, and easily occurs calculating
The faults such as machine disorder, loss of data and equipment are out of service, even cause the electrical equipment on internal combustion engine generator unexpected time serious
Damage.
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.
