500KVA Yuchai Diesel Generator Set Unload Container In Bangkok | Hospital Back Up Power

400kW Yuchai diesel generator set provides reliable backup power for a hospital in Bangkok. The hospital’s backup power system constitutes a multi-tiered power assurance framework, primarily comprising diesel generator sets serving as the main backup source, alongside UPS (Uninterruptible Power Supply) units that act as the final line of defense for critical equipment. 

⚙️ Core Equipment: Diesel Generator Sets
These form the core of the hospital’s backup power system; they automatically start shortly after a utility power outage occurs, providing sustained electrical support to critical areas and equipment throughout the entire hospital.

Configuration Requirements: According to the “Code for Electrical Design of Medical Buildings”, Class III hospitals are mandated to install emergency diesel generator sets, while Class II hospitals are “recommended” to do so. In actual practice, many hospitals adopt a “dual utility feed + diesel generator” configuration to ensure the highest level of power supply reliability.

Key Performance Indicators:

Startup Speed: Upon the loss of utility power, the diesel generator set must automatically start within 15 seconds and begin supplying power to the designated electrical loads.

Continuous Operation Duration: For Class III hospitals, the fuel tank capacity must be sufficient to support the generator set’s continuous operation for a period exceeding 24 hours.

Real-world Example: The Yulin Maternal and Child Health Hospital is currently procuring a 1005kVA diesel generator set. The specifications require automatic transfer within 15 seconds of a utility power failure; the onboard fuel storage must be capable of sustaining continuous power for at least 3 hours during a fire emergency, while also featuring a reserved interface to facilitate refueling for extended operation exceeding 24 hours.

🛡️ The Final Line of Defense: UPS (Uninterruptible Power Supply)
For equipment where any power interruption is absolutely impermissible—such as in operating rooms, ICUs (Intensive Care Units), neonatal wards, and medical refrigerators—relying solely on generator sets is insufficient. This is because there is an inherent, albeit brief, transition period between the generator’s startup and the stabilization of its power output (even though this process is required to be completed within 15 seconds). Consequently, a UPS (Uninterruptible Power Supply) is required to bridge this power “gap.”

Core Function: To achieve a 0-millisecond transfer time, thereby ensuring absolute continuity of power supply and safeguarding precision medical equipment—as well as patient life support systems—against the adverse effects of power outages.

Backup Duration: The energy storage capacity (batteries) of a UPS typically needs only to be sufficient to sustain power for a duration exceeding 15 minutes. These 15 minutes are intended to “bridge the gap” until the diesel generator successfully starts up and runs stably, thereby creating a seamless handover.

  Prime power (PRP): Prime power is available for an unlimited number of annual hours in available load application, in according with GB/T2820-97(EQVLso8528); A 10% overload capability is available for a period of 1 hour within a 12-hour period of operation.

  Standby power Rating (ESP): The standby power rating is application for supplying emergency power for the duration of a utility power interruption. No overload, utility parallel or negotiated outage operation capability is available at this rating.
