What are the specific benefits of EPS power supply to metro operations?
The benefits of EPS power system in subway operation are many, including:
High reliability
EPS power system adopts modular parallel design, which can realize parallel backup of N+1 modules. Even if some modules fail, it does not affect the operation of the whole system. This redundant design greatly improves the reliability of the system.
Low operating cost
The EPS system runs intelligently, realizes fault location and battery management through touch screen monitoring, prolonging battery life and reducing maintenance costs. At the same time, the modular design makes the maintenance simple and fast, reduces the maintenance time, and improves the availability of the system.
Energy saving and emission reduction
EPS system uses high-efficiency power conversion technology to improve power efficiency and save energy. This design not only reduces energy consumption, but also meets the requirements of modern environmental protection.
Output waveform advantages
Compared with the traditional EPS composed of frequency converters, the modular EPS output is pure sine wave, which has no impact on sensitive equipment, and the integrated output waveform harmonic interference is serious.
Emergency lighting and evacuation instructions
The EPS power supply system provides a highly reliable power guarantee for the fire emergency lighting system in the subway station, ensuring that personnel can be safely evacuated in an emergency.
High degree of automation
EPS power supply system has a high degree of automation, can automatically and accurately locate faults, and can quickly solve and eliminate faults through simple guidance to personnel, making up for the lack of personnel maintenance technology.
Simple maintenance
EPS power system generally integrates battery management software and hardware systems, which can monitor each battery in real time locally and remotely, and carry out automatic charging and discharging regularly, so as to facilitate maintenance personnel management and reduce maintenance workload.
Strong adaptability
EPS power system for the working environment requirements are not particularly high, increase its popularity and scope of use, especially for some subway station environment is relatively harsh.
Short power switching time
The switching time of mains power supply to emergency power supply of EPS equipment is less than or equal to 3ms, which is crucial for subway stations to respond to demand.
Reduce panic and improve the implementation of accident handling plan
The independently set EPS system will not cause unnecessary panic due to a large area of power loss caused by a fault, and greatly improve the implementation of subway accident handling plan.
CONCLUSION
In summary, EPS power supply system provides multiple benefits such as high reliability, low cost operation, energy saving, environmental protection and fast response in subway operation, and is the key technical support to ensure the safe operation of subway.
