Description
Technical field
The present invention relates to Ship Electrical Power System and bank electricity system, more particularly to a kind of seamless grid-connecting apparatus of intelligent bank electricity.
Background technology
Ship shore electric refer to ship stopped using during berthing on the generator on ship, ship divulge information, illuminate, refrigeration etc. its
His facility operating all changes is powered by harbour, so as to reduce the power supply mode of marine exhaust discharge.Bank electricity system is mainly become by port area
The composition such as electric institute, on the bank supply unit, bank electricity reception device and cable connection device.Spot ship bank electricity technology is present asks as follows
Topic：
1st, bank electricity voltage and frequency multiplex.
The professional standard issued in Department of Transportation of China《Yard craft shore-based power supply systems technology condition》In just clearly
Define the bank electricity system that 6.6kV high pressures are gone on board and 400/450V low pressure is gone on board two kinds of voltage standards, cause China harbour to be equipped with
Need to consider three kinds of voltages.
Be additionally based on various countries line voltage frequencies different, low-voltage ship diesel generating set be usually 400V/50Hz,
The major class products of 450V/60Hz two.The electricity of China's harbour distribution network is made as 10kV/50Hz, 6kV/50Hz and 380V/50Hz, so I
State harbour and ship must take into consideration voltage, the transfer problem of frequency.
2nd, power supply system is incompatible.
Port and pier generally add the zero potential protection system (i.e. TN systems) of protective wire, the neutrality with ship using three-phase and four-line
Point is earth-free or incompatible through high resistance ground system (i.e. IT system) standard.Zero potential protection system (i.e. TN systems) and neutral point are not
Ground connection or the key difference through high resistance ground system (i.e. IT system) are arranged in the protection used for occurring singlephase earth fault
Apply difference.
When occurring singlephase earth fault, zero potential protection system (TN systems) is using the concatenation electric leakage in the neutral conductor (N lines)
Flow sensor, three-phase current is vector superposed is not zero for reflection, so that Crush trigger or electronic component make circuit breaker trip, interrupts
Power supply guarantees personal safety.And isolated neutral or the neutral conductor (N is not generally exported through high resistance ground system (i.e. IT system)
Line), its earth current very little (electric current is generally less than 10A) when occurring singlephase earth fault does not result in human casualty accident,
Trouble shooting is pointed out using insulating monitoring warning device, it is to avoid occur phase fault accident in industry.Using bank electricity zero connection protection
System (i.e. TN systems) is directly to the isolated neutral of ship or when being powered through high resistance ground system (i.e. IT system), although N
Line breaks ship, but ship housing and seawater, the earth are connected, and ship shore electric is equivalent to employing protective grounding system (i.e. TT systems
System).Once generation singlephase earth fault, it switchs meeting trip protection at once, and ship power supply is interrupted immediately, it is impossible to meet ship use
The requirement of electric continuity, its reliability powered is substantially reduced, and can then be produced for large-scale important port area, military harbour base huge
Big economic loss and political fallout.As a result of zero potential protection system (i.e. TN systems) directly to ship power supply, arrive on the bank
The service cable of ship can produce small leakage current, and long-play can produce corrosion to the reinforcing bar on harbour, so as to drop
The service life of low harbour reinforcing bar, life danger can be then brought for underwater operation personnel and maintenance personal；If exclusively for port
The a set of isolated neutral of Ship Design of pulling in shore of mouthful harbour or through high resistance ground system (i.e. IT system) power supply, then cost of investment
Increase, because of isolated neutral or through high resistance ground system (i.e. IT system) power supply standard can not conveniently economically output 220V be electric
The single-phase equipment of pressure supply is used, without using very uneconomical, and because ship pulls in shore that the time is less, equipment is long during ship not in shore
Time is to be in idle state, and the environment of port and pier is again more severe (humidity, salt fog etc.), and the easy aging of component is used
Life-span is shorter.Therefore, port and pier are badly in need of zero potential protection system (i.e. TN systems) with isolated neutral or through high resistance ground system
The compatible power system pattern of (i.e. IT system) power supply system phase of uniting.
3rd, the access grid-connected scheme of bank electricity can not be general.
The high-voltage variable frequency power source for being equipped with 6.6kV 50/60Hz that each harbour of China has according to own situation, has
450V/60Hz low-voltage variable frequency power supplys are equipped with, what is had is only furnished with 380V/50Hz bank electricity, so ship is stopping different harbours
Shi Keneng needs to connect different shore electric powers.Being carried out on usual ship between two generating sets can be by adjusting when load is shifted
The rotating speed of two generating sets of section realizes quick transfer, but when the transfer that generating set is loaded in bank electricity and ship again
It is different.Current China does not have special standard for continuous electrotransfer between generating set on ship shore electric and ship, causes
Many ships install at a loss as to what to do during bank electricity device additional, and many crewman do not know how to use, be that the popularization of bank electricity brings barrier
Hinder.
When ship reaches port, ship needs to be powered by marine generator group to be transformed into bank electricity and power, when leaving harbour by bank
Electricity power supply is transformed into electric set electric supply, if to undergo the power-off of short time on ship using power-off switching, while on ship
Many equipment such as lighting installation, navigation equipment, auxiliary equipment be required for resetting manually, therefore need in many cases not
Power-off carries out the switching (i.e. " power-off is powered again " mode) between bank electricity and generating set, causes complex operation step complicated.
The content of the invention
The technical problem to be solved in the present invention is that there is provided a kind of intelligent bank in order to overcome the drawbacks described above of prior art presence
Electric seamless grid-connecting apparatus.
The present invention is to solve above-mentioned technical problem by following technical proposals：
