Description
Technical field
The invention mainly relates to energy technology fields, refer in particular to a kind of ocean anchoring uninterrupted micro power source system of floating platform off-network
System and floating platform power supply system.
Background technique
Ocean anchoring floating platform is the important marine information engineering equipment of open sea regions information network covering in solving.Traditional
The floating platform energy resource system that anchors is a kind of independent micro-grid system, is complemented each other using various energy resources and forms electricity generation system, is electronics
Information floating platform load equipment provides energy resource supply.Anchoring floating platform energy resource system has the characteristics that following: (1) photovoltaic generation unit
Energy is incorporated to ac bus, and preferential supply load, dump energy is by two-way inverter to battery charging.Battery group is filled
Man Hou, if electric energy still has residue, system limits power output to photovoltaic DC-to-AC converter, only meets load power demand；(2) photovoltaic
When generator unit energy is unable to satisfy load, the electric discharge of battery group, being incorporated to ac bus by two-way inverter is load supplying；
(3) when photovoltaic generation unit and battery group are all unable to satisfy loading demand, diesel power generation is incorporated to friendship by two-way inverter
Stream bus is load supplying, while being battery charging.UPS, i.e. uninterruptible power supply, containing energy storage device and inverter,
It is mainly used for providing continual power supply to power electronic equipment.When ac bus input is normal, UPS is by busbar voltage
Load is supplied after stabilization, while internally battery charges；When ac bus power-off, internal electricity is passed through inversion immediately by UPS
It is converted into the supply load of 220V alternating current, load is made to maintain to work normally.When conventional UPS ensures emergency set operation in one week
Between, need matched battery capacity larger.Anchor lantern, emergency Beidou, the emergency sets such as Beidou host rated power about 60W, one
All power consumption is 10.08kwh, it is contemplated that UPS efficiency is usually 80%, while the depth of discharge that plumbic acid exempts to tie up battery is 0.7, that
The battery capacity of UPS configuration is 18kwh, and the battery of 12V/100AH needs to configure 15 pieces, heavy and account for cabin volume.UPS system
System is depleted of energy type, and without maintenance of going to sea in one week, floating platform will be in lost contact state.
Energy resource system is spread in deck, each cabin and radome fairing through entire anchoring floating platform stage body.Wherein, it is located at first
The photovoltaic module of plate is faced with the test of typhoon.Real case shows 10m high wave caused by 14 grades of typhoons, to round deck
The component of half sector damages.Energy resource system after impaired is unable to maintain that the normal work of each equipment of floating platform, sets at these
In standby, emergency Beidou provides the location information of floating platform, and anchor lantern is that floating platform stands on the alarm signal in ocean, and the two needs lasting
It powers to ensure the positioning and maintenance safe and convenient of going to sea of floating platform.Therefore, it is necessary to a reliable and stable off-network type is uninterruptedly electric
Source is emergency Beidou and anchor lantern power supply.Currently, UPS scheme is mostly the input of conventional electric power alternating current 220V, it the use of the time is mostly rather
Clock, most a few houres, its more than continuous work week age reliability not can guarantee.Uninterrupted energy resource system is that anchoring floating platform is answered
Anxious Beidou and the reliable and stable long-term running guarantee of anchor lantern.The shortcomings that existing uninterrupted energy resource system:
1) except UPS carries energy storage battery, without other energy sources after ac bus power-off, cruise duration is short；
2) operating time is directly proportional to accumulator capacity volume weight, systems bulky.
In energy resource system more at present, due to the not uninterrupted energy, emergency Beidou, anchor not can guarantee after full court power-off
The emergency sets such as lamp work reliably and with long-term, and system integrity is low, and reliability is relatively low.
In the existing oily compound energy power supply system of anchoring floating platform scene, by suitable control strategy, preferential scene etc.
Natural energy resources are aided with diesel engine power supply, guarantee off-network anchoring floating platform normal power supply using the energy management mode provided multiple forms of energy to complement each other.But
It is not have uninterruptible power supply supply emergency load.Meanwhile energy-storage battery capacity is limited inside traditional UPS, does not have length
The ability of time supply emergency set.UPS, which extends out energy-storage battery, can extend certain working time, but still not have sustainable confession
The ability of electricity, while the energy-storage battery extended out increases the cost of system.
