Description
Technical field
The utility model relates to transformer station's power supply unit technical field, is specifically related to a kind of AC/DC integrated power-supply system.
Background technology
At present, transformer station one general configuration three overlaps separately independently operating power system, i.e. direct current operative power source DC, DC transformating power DC/DC, ac uninterrupted power supply UPS, often overlaps power-supply system and configures separately battery room, batteries and monitoring management system.For the DC power system that control, signal, protection, automatics and some actuator etc. power, be commonly referred to direct current operative power source.For the AC power supply system that the equipment such as microcomputer, carrier wave, fire-fighting are powered, be commonly referred to alternating current operation power supply; For the DC power system that the communication equipment such as switch, telemechanical is powered, be then called DC transformating power DC/DC, also known as communication power supply.
Direct current operative power source DC is normal in station AC power or under accident condition, all in transformer station, can keep the power supply of reliable power supply by the equipment such as control overhead and all kinds of DC motor, breaker switching-on mechanism such as all control, protection, automatics.The system voltage of direct current operative power source DC generally selects 220 V or 110 V, adopts earth-free mode.All install two group storage batteries and two cover charging devices to 220KV and above transformer station, form two electricity two and fill mode, adopt single-trunk segmental wiring, establish contact electrical equipment between two sections of buses, two group storage batteries and two cover charging devices are connected to different bus section, busbar section respectively.The maturation of intelligent high-frequency switching mode power supply technology from the nineties, achieve modularization and Hot Spare in parallel operation, batteries then adopts non-maintaining analysing valve control type lead-acid accumulator battery, distributed computer and field bus technique is adopted to carry out centralized monitor to DC power system, improve the intelligent management level of charging module and property easy to maintenance, reliability and the technical merit of system cloud gray model achieve qualitative leap, replace phase-controlled power and extensive use completely at present in transformer station.
DC transformating power DC/DC is also known as communication power supply, and it is the power supply of the communication equipments such as transformer station's intercarrier machine, optical transmitter and receiver and protection multiple connection equipment.The system voltage of communication power supply is 48V, adopts plus earth mode.Design is filled by two electricity two by 220 KV and above transformer station, adopts single bus scheme, and two group storage batteries and two cover charging devices are connected to different bus section, busbar section respectively, do not establish contact electrical equipment between two sections of buses.
Ac uninterrupted power supply UPS for not allow the computer monitoring equipment had a power failure in short-term to power, requires higher in transformer station in reliability and stability.Ac uninterrupted power supply UPS generally all adopts the using and the reserved series operation mode, by host supplying power time namely normally, automatically drops into during hostdown from machine.By ac power supply under ac uninterrupted power supply UPS normal condition, when AC power disappears or the element fault such as rectifier, inverter, then powered to the load through inverter by the storage battery carried.From the mid-90, ac uninterrupted power supply UPS widely applies in transformer station, because its built-in battery group capacity is little and do not have the maintenance measure of specialty, becomes the potential uncertain factor threatening transformer station stable operation.
Transformer station's configuration three cover separately independently operating power there is following problem: 1. cannot complex optimum resource, independently operating power system repeated configuration batteries separately, makes once to invest increase.2. the equipment of dispersed placement adds day-to-day operation maintenance work.3. because the difference of the technical standard of the different suppliers of each operating power causes the difficult coordination such as power supply installation, service.
Utility model content
Arrange the problems such as dispersion for the repeated configuration batteries existed in prior art and power supply and watch-dog thereof, of the present utility modelly propose a kind of AC/DC integrated power-supply system.
The technical solution of the utility model is:
A kind of AC/DC integrated power-supply system, comprises direct current operative power source DC, ac uninterrupted power supply UPS and centralized monitor module.The direct-flow input end of ac uninterrupted power supply UPS connects the batteries of direct current operative power source DC, and the direct-current supervision module in direct current operative power source DC and the UPS monitoring module in ac uninterrupted power supply UPS connect the input of centralized monitor module.
Concrete, AC/DC integrated power-supply system also comprises DC transformating power DC/DC, the direct-flow input end of DC transformating power DC/DC connects the batteries of direct current operative power source DC, and the communication monitoring module in DC transformating power DC/DC connects the input of centralized monitor module.
The beneficial effects of the utility model: the three class power supplys (direct current operative power source DC, ac uninterrupted power supply UPS and DC transformating power DC/DC) needed for substation operation integrate by the AC/DC integrated power-supply system set up according to the technical solution of the utility model, the batteries of three class power supplys all uses the batteries of direct current operative power source DC, the quantity of batteries is reduced to one by three, avoid repeated configuration batteries, save the one-time investment that power-supply system is built.Three class power supplys use unified centralized monitor module, and the information of achieving focuses on and analyzes, and are conducive to increasing work efficiency.AC/DC integrated power-supply system can be mainly used in the field such as electrical network, generating, can be used as the AC and DC uninterrupted power supply of divide-shut brake, relaying protection, automatics, signalling etc. of each power automatic system in transformer station, communication system, distant place executive system, primary cut-out.The utility model is applicable to different transformer stations and powers occasion, and power supply performance is reliable and stable, has larger application and promotes space.
