Currently transportation has become one of the most important industry of the national economy. Development and implementation of the strategy and its supporting policies overall national economic development is closely related to the transportation industry. High-speed rail construction is the next period of time the focus of China's railway construction, but the significance of high-speed rail construction not only reflected provides a convenient mode of transportation, for the manufacturing sector in China, more important is pulling its upgrading, technical upgrade. It is therefore important for each room of the transport industry information room, communications room, the control center has played an important role in the information store, traffic information coordination, monitoring, and other sites, in case of failure will bring loss of information, traffic chaos and even major security incidents, significant loss of life and property.

 

The transport industry, power system load characteristics

1, the civil aviation:

Terminal information room, communications room: Normally a computer, server load, depending on the size around the airport showing different size, load range with a total capacity ranging from 20KVA ~ 200KVA

Radar Station: radar detection system and instrumentation equipment for power, to 20 ~ 60KVA major capacity range

Air Traffic Control Center: monitoring system to provide uninterrupted power supply, with a total capacity of large-capacity main

 

2, highways:

Toll Station: Load main charge PC, signal indicator systems, data transmission equipment, primarily to small and medium-capacity, 3 ~ 15KVA

Tunnels: Load for emergency lighting, fire protection, ventilation systems, the capacity of 80 ~ 120KVA

Highway Administration billing and monitoring center: the data processing load for the billing center (server), monitoring, office automation equipment, providing services and a full exchange of information to monitor the road for the entire highway system all its computers and server load capacity than the large, depending on the size of the different highway capacity range roughly 30KVA ~ 120KVA;

 

3, water areas:

Port of billing systems: billing system for power capacity range of small-capacity main

Information and Monitoring Center Harbor Bureau: powered equipment for surveillance system, the capacity range of about 30KVA ~ 80KVA

 

4, railway and metro rail areas:

Stations, control and communication system center: the capacity of small and medium capacity mainly about 10KVA ~ 60KVA

Signal System: powered signal system equipment, mainly small capacity of about 1 ~ 10KVA

Integrated monitoring system: for environmental control equipment, instrumentation equipment, power supply, mainly to large capacity, the capacity range of about 30KVA ~ 200KVA

Above for reference only, specific capacity may vary depending on the system size, the application of different venues.

 

The current status of the existence of deficiencies in the transportation industry UPS applications are:

1, in the transportation industry, UPS power supply applications, in order to disperse the single main power supply, bring the system failure risks;

2, unit capacity is too small, the basic stand-alone single out and to single out three main, only a small number of terminals, Air Traffic Control, Highway Authority has a small amount into three three large-capacity UPS application, low power UPS reliability design low.

 

Recommended for customers N + X redundancy and centralized power and high reliability solution:

1, change the current status of decentralized power supply, centralized power supply scheme based;

2, due to the importance of the transport sector, it is recommended to communicate information to the transport sector in the engine room, billing systems, integrated monitoring system and other critical systems as well as the large signal, radar detection systems, we recommend using the Prostar Uranus (Uranus) three-three series industrial UPS and Neptune (Neptune) single out three series of industrial-type UPS 1 + 1 and machine program.

 

Centralized power and 1 + 1 parallel program advantages:

1, the centralized power of the economy: you can see, UPS is the average price per KVA capacity decreases with the increase, in other words, the same size of the exchange system, using centralized power saving investment funds tend to be more dispersed than the supply.

2, centralized power and high reliability: With the increase of UPS capacity, high-capacity UPS reliability than small capacity and reliability.

3, centralized power to make a more rational distribution planning, reducing installation space, easy maintenance and management.

4,1 + 1 and machine systems for the transportation industry to provide important load system with high reliability power supply systems, 1 + 1 parallel system reliability is a stand-alone 5.5 times, reliability has been significantly improved.
