Commercial complex intelligent power distribution system project

Project overview

Provide integrated solutions for high and low voltage power distribution, emergency lighting, fire power supply, and smart metering for 200,000 square meters of commercial space, covering shops, restaurants, cinemas, and office buildings.

Indonesia fit

Help commercial entities select high and low voltage power distribution, merchant metering, fire power supply, emergency lighting and energy-saving renovations in one go, solving the problems of inconsistent specifications of multi-business shops, bill disputes and holiday delivery guarantees; the system adapts to Indonesia's 230/400V, 50Hz commercial power, Type C/F socket terminals and peak customer flow loads in shopping malls.

Professional configuration and standards

Low-voltage cabinets and metering boxes are configured in accordance with IEC 61439, fire and emergency power switching are configured in accordance with IEC 60947 ATS requirements, branch circuits use RCBO/MCCB graded protection, and key catering circuits are checked according to oil smoke, moisture and harmonic loads; the equipment has completed ATS switching, EPS discharge, temperature rise, insulation, energy meter accuracy and grounding continuity tests, and the data meets SNI/PUIL and fire acceptance.

Delivery challenges and solutions

a.Challenge: Loads surge during Indonesian holidays and shopping festivals, and deviations in capacity calculations can easily lead to peak tripping.

Solution: Accurately calculate peak and valley loads based on local passenger flow and consumption data, reserve 25% of peak capacity, and ensure zero tripping during holiday peaks.

b.Challenge: There are more than 300 shops, and the workload of manual meter reading and electricity bill collection is huge, and there are many disputes at public stalls.

Solution: Deployed a one-household-one-meter smart metering system to automatically generate Indonesian bills, support online payment, and increase the collection rate to 98%.

c.Challenge: The local fire acceptance standards are strict and the emergency power switching requirements are high.

Solution: Equipped with fire EPS emergency power supply + dual power automatic switching, the switching time is ≤0.25s, and it can pass the fire protection acceptance in one go.

Project results

There are zero trippings during holidays, reducing operating losses by more than 800,000 yuan per year on average; electricity bills are automatically collected, reducing labor costs for financial collection by 80%; sub-item metering assists energy-saving renovations, resulting in comprehensive power savings of more than 10%.
