One-stop power distribution system solution for industrial parks

Detailed plan description

For industrial park management committees and settled enterprises, we provide overall services for 10kV/0.4kV full voltage power distribution systems, covering the entire process of early capacity planning, equipment supply, installation and construction, power acceptance and delivery, and later operation and maintenance. It adopts a modular power distribution architecture to support phased construction and flexible capacity expansion, adapting to the power needs of various types of enterprises such as mechanical processing, electronic manufacturing, warehousing and logistics, and is simultaneously equipped with smart metering and energy consumption management systems to achieve visualization and refined management of power consumption in the park.

Adapted to Indonesia

Solve the procurement issues of "capacity expansion without stopping production, unified specifications, cost sharing, delivery coordination and after-sales operation and maintenance" for the park management committee, EPC and settled factories. The solution integrates 20kV/0.4kV power supply and distribution, transformers, MV/LV switchgear, AMI household metering, harmonic control and remote operation and maintenance to meet the needs of Cikarang, Bekasi, Karawang and other industrial belts for reliable power supply and rapid production.

Professional specifications and standards based

It is recommended that the medium-voltage side be planned as a 20kV system, and the low-voltage side be 400/230V, 50Hz; transformers are commonly used in parallel or partitioned configurations of 630kVA-2500kVA. The short-term withstand current of the low-voltage cabinet is checked according to 50kA/1s or the short-circuit capacity of the project. The power factor target is not less than 0.95. THDi/THDu is recommended to be controlled within the relevant limits of IEC 61000. Refer to IEC 60076, IEC 62271, IEC 61439, IEC 62053, SNI/PLN access requirements.

Original experience and test data

Scarce experience: The failure of the second phase expansion of the park is often caused by the failure to reserve busbars, cable trenches and CT/PT space in the first phase.

Pitfalls and pain points that I have stepped on

• The initial planning capacity is insufficiently reserved. Later, when enterprises move in to expand capacity, they will need to undergo power outages and modifications, resulting in production interruption and construction period loss;
• The park's load fluctuates greatly, voltage drops during peak periods, and harmonic pollution is serious, causing precision production equipment to shut down and products to be scrapped;
• Multiple enterprises share the power distribution system, the metering of shared electricity bills is unclear, and cost disputes between enterprises occur frequently;
• The power distribution room lacks professional operation and maintenance, and fault detection is delayed. The loss of a single power outage can reach hundreds of thousands of yuan.

Core parameters

The voltage level is 10kV/0.4kV, the single-park adaptation capacity is 500kVA~10MVA, the power factor is ≥0.95, the power supply reliability is 99.9%, the energy measurement accuracy is 0.5S level, and the harmonic distortion rate is ≤5%.

Our special contribution

• Reserve 30% capacity expansion margin in advance planning, and use pull-out modular power distribution cabinets, so that later capacity expansion can be done without power outage;
• Standard reactive power compensation + active filter device completely solves the problems of voltage fluctuation and harmonic interference;
• Deploy an intelligent AMI household metering system to automatically allocate public electricity bills and make bills transparent and checkable;
• 7×24-hour remote monitoring platform + localized operation and maintenance team, fault response on-site within 2 hours, and annual power outage duration reduced by 80%.

Project income

• Economic benefits: The annual power outage duration is reduced by 80%, and the average annual reduction in production shutdown losses for a single thousand-acre park is more than 2 million yuan; after the power quality is optimized, the failure rate of precision equipment is reduced by 70%, and the service life of the equipment is extended by 25%; shared electricity bills are automatically calculated, and financial reconciliation labor costs are reduced by 60%.
• Management benefits: Modular expansion without power outages shortens the second-phase expansion period by 70%, without the need for enterprises to stop production and cooperate; remote centralized monitoring replaces manual inspections, and the labor cost of power distribution room operation and maintenance is reduced by 50%.
• Safety benefits: Harmonic and voltage fluctuation problems are eliminated, the downtime rate of precision production equipment is reduced to 0, and the product defect rate is reduced by 2% to 3%.
