Group of model of 800V HVDC electric power: Group of model of 800V HVDC electric power and program of traditional UPS power supply are parallel
As the ceaseless development of technology of electric power electron, high-pressured dc (HVDC) power system applies with what allocate a domain in power transmission more and more extensive. In numerous HVDC technology, group of model of 800V HVDC electric power because its efficient, reliable characteristic, got pay close attention to extensively. Article general undertakes contrasting analytic around group of model of 800V HVDC electric power and plan of traditional UPS power supply, with period provide beneficial reference for relevant enterprise and industry.
One, brief introduction of group of model of 800V HVDC electric power
Group of model of 800V HVDC electric power is one kind is based on high-pressured dc (HVDC) electric power module of the technology, have volume small, weight light, efficiency tall, dependability is advanced advantage. This model group is main wait for composition by inverter, filter, transformer, capacitor, can come true to shed the changeover of dc continuously, wide application generates electricity at new energy resources, the domain such as traffic of industrial automation, orbit.
2, brief introduction of plan of traditional UPS power supply
Traditional UPS (UPS) power supply plan is pattern of a kind of familiar power source safeguard, basically wait for composition by inverter, batteries, load. UPS is town report changeover dc when town report is regular, memory is in batteries; When town report is unusual, UPS instantly switch comes batteries power supply, ensure load is stabilized continuously move.
3, group of model of 800V HVDC electric power and program of traditional UPS power supply are parallel
1.Efficiency is comparative
The efficiency of group of model of 800V HVDC electric power is taller, be in commonly 98% above, and the efficiency of plan of traditional UPS power supply is in commonly 90% the left and right sides. This is meant in identical load the condition falls, group of model of 800V HVDC electric power can save the sources of energy of about 8% to use up.
2.Bulk and weight are comparative
Volume of group of model of 800V HVDC electric power small, weight is light, facilitating installation and carry. Under photograph comparing, volume of program of traditional UPS power supply is larger, weight is heavier, install and carry relatively disadvantageous.
3.Dependability is comparative
Group of model of 800V HVDC electric power is used modular design, have better reliability. When malfunction, need to change only breakdown module can return to normal move. And plan of traditional UPS power supply is in when malfunctioning, the likelihood needs to change whole system, maintenance cost is higher.
4.Safeguard cost contrast
Group of model of 800V HVDC electric power maintains cost inferior, main watch is the following now two respects: It is modular the design facilitates safeguard; Rate of 2 hereat barrier is inferior, decreased to maintain a number. And plan of traditional UPS power supply maintains cost taller, main watch is the following now two respects: It is bulk bigger, maintenance difficulty is taller; Rate of 2 hereat barrier is higher, maintenance time is more.
5.Applied domain is comparative
Group of model of 800V HVDC electric power applies to new energy resources to generate electricity, the domain such as traffic of industrial automation, orbit. And plan of traditional UPS power supply applies to taller to demand of power source stability circumstance, wait like data center, hospital, bank.
4, conclusion
The place on put together is narrated, group of model of 800V HVDC electric power is in efficiency, bulk, weight, dependability, safeguard the respect such as cost to have clear advantage, it is a kind of electric power solution that deserves promotion. Extend with what use a field as ceaseless development of the technology, hopeful of group of model of 800V HVDC electric power produces bigger effect in prospective power system.
It is when solution of electric power of choose and buy, the enterprise should consider integratedly according to the element such as setting of oneself demand, application, choose suitable plan. In the meantime, pay close attention to the development of new technology, use up in order to reduce the sources of energy, raise economic benefits.
