Highly reliable power supply system solution for hospitals

Detailed plan description

For general hospitals and specialized hospitals, it is designed in strict accordance with the power supply standards of medical buildings, covering all areas such as outpatient departments, inpatient departments, operating rooms, ICU, imaging departments, and laboratory laboratories. For the first-level load and the particularly important load in the first-level load, a multi-level redundant architecture of dual power supply + UPS + diesel generator is adopted, matched with a medical IT isolated power supply system to ensure the safe and stable operation of medical equipment.

Adapted to Indonesia

Solve the problems of "key loads cannot be stopped, UPS/diesel engine switching, medical isolation power supply, and construction cannot affect diagnosis and treatment" for hospitals, clinics and medical parks. The procurement side gets the overall package of graded loads, ATS/UPS, medical IT systems, isolation transformers, alarm monitoring and maintenance plans.

Professional specifications and standards based

It is recommended that the key loads of hospitals be classified according to the first/secondary load. Medical IT isolation systems and insulation monitoring can be used in medical places such as operating rooms and ICUs; UPS online double conversion and ATS switching time are determined according to the load level. Refer to IEC 60364-7-710, IEC 61558, IEC 62040, IEC 61439, IEC 60947, and combine the fire protection and electrical acceptance requirements of Indonesian hospital projects.

Original experience and test data

Scarce experience: The difficulty in hospital renovation is not equipment procurement, but construction windows and temporary power supply switching.

Pitfalls and pain points that I have stepped on

• Power outages in key areas such as operating rooms and ICUs directly endanger patients' lives, and the power supply fault tolerance rate is zero;
• Medical precision equipment has high requirements on power quality, and harmonic interference can cause detection data deviation and equipment failure;
• Medical equipment has a high risk of leakage, and ordinary power distribution systems cannot meet personal safety protection requirements;
• The hospital operates 24 hours a day, and power distribution transformation and operation and maintenance cannot affect normal diagnosis and treatment.

Core parameters

Dual power supply for primary load. For particularly important loads, UPS power supply time is ≥30 minutes, diesel generator start-up time is ≤15s, medical IT system insulation monitoring accuracy is 1kΩ, and harmonic distortion rate is ≤3%.

Our special contribution

• Three-level redundant power supply architecture, zero risk of power outage in key areas, fully compliant with hospital power supply grade standards;
• System-wide harmonic control ensures stable operation of precision equipment such as CT and NMR and accurate detection data;
• Operating rooms and ICUs are equipped with IT isolation power systems as standard, which will not trip due to current leakage, ensuring the personal safety of doctors and patients;
• Non-power outage operation and maintenance plan, staggered inspection and renovation at night, will not affect normal diagnosis and treatment during the day.

Project income

• Safety benefits: The power supply reliability in key diagnosis and treatment areas reaches 99.999%, completely eliminating medical safety accidents caused by power outages and avoiding major medical disputes and compensation risks; the isolated power supply system ensures the personal safety of doctors and patients, and the risk of electric shock is reduced to zero.
• Economic benefits: After harmonic control, the service life of medical equipment is extended by 25%, and the cost of updating high-end imaging equipment is saved by more than 20% on average annually. No power outages are required for renovation and construction, and there is no need to stop clinics, thus avoiding revenue losses due to outages.
• Management benefits: The entire power distribution system is remotely monitored, logistics operation and maintenance efficiency is increased by 40%, and night duty labor costs are reduced.
