2x2500kVA Substation Contractor Quanganhcons and Perfect Service

QuangAnhCons is a contractor specializing in constructing high-capacity substations, notably the 2x2500kVA project in Nhon Trach II. This project supplies electricity to the RVN Fibers factory, showcasing excellent technical and project management capabilities.

The importance of the 2x2500kVA substation

The 2x2500kVA substation at Nhon Trach II is a critical project supplying electricity to the RVN Fibers factory. With a large capacity of up to 5000 kVA, it effectively serves the factory’s power requirements. The 2x2500kVA substation contractor Quanganhcons ensures that all stages from design to installation comply with the strict standards of Vietnam’s power industry.

The 2x2500kVA substation is an essential system in the power transmission and distribution network in Vietnam, especially in areas with high power demands such as factories, industrial zones, and high-rise buildings. With a total capacity of 5000 kVA, this substation ensures stable and continuous electricity supply to large loads.

The use of two transformers in the system not only enhances electrical stability but also increases operational safety. In the event of a transformer failure, the other can continue to operate to ensure uninterrupted power supply, which is particularly important for areas demanding high electrical reliability such as hospitals or defense agencies.

A large capacity substation enables efficient power distribution thanks to its ability to transmit electricity at high capacity. Its flexible design allows the substation to be placed outdoors or in a technical room, optimizing compatibility with the specific project. Another crucial factor is that this substation helps save costs and energy in operation, reducing electrical losses due to transmission and conductor power loss.

Furthermore, the operational flexibility of the substation is enhanced with the ability to alternate or reserve between the two transformers, minimizing power outage risks during maintenance or failures, thereby increasing the safety of the electrical system. In the field of construction and energy, the 2x2500kVA substation not only distributes optimal capacity but also supports suitable designs that help save conductors and ensure electrical safety.

With the ability to serve various economic sectors with high power demands, from industrial zones to high-end residential buildings, this substation plays a core role in providing stable and efficient power supply.

Technology and engineering applied in substation installation

The 2x2500kVA substation contractor Quanganhcons applies modern technology with high-quality 2500kVA transformers, along with ACB 4000A switchgear and 1000 kVar reactive power compensation. Combining advanced technology and a skilled team, this substation ensures stable operation under a 22kV voltage structure.

During substation installation, the application of advanced technology and engineering is crucial to ensure efficiency and safety. The standard construction process includes multiple critical stages. First, thorough site surveys are conducted to determine the foundation positions and medium-voltage cable routes, ensuring optimal installation locations.

Subsequent steps include foundation excavation, protective cable duct installation, and grounding system construction to protect and ensure operational safety of the substation against leakage currents, lightning, and storms. Concrete foundation pouring and the erection of components such as circuit breakers, operating chairs, beams, insulators, to transformer installation, cable connections, and warning sign installation are indispensable steps. Especially for ultra-high voltage substation installation, modern device installation technologies and testing under the execution of highly qualified engineers are necessary to ensure the substation’s computer control system operates precisely.

Depending on the requirements and terrain conditions, there are various types of substations used with corresponding technology applications:

• Pole-mounted substations suitable for outdoor environments due to their low cost and compact design.
• KIOS substations, easy to move and aesthetically pleasing, optimized for confined spaces like industrial workshops.
• Indoor substations ensure safety, suitable for large industrial plants needing minimal disruption.
• Single pole substations, with a compact design, also fit crowded areas.
• GIS substations, the most advanced with SF6 gas-insulated switchgear, significantly reduce the required area compared to outdoor substations, ideal for space-constrained areas like major cities.

The control and automation system with SCADA technology is integrated for automatic monitoring and operation of devices, ensuring the stability and safety of the power grid.

In summary, the combination of advanced technologies from the construction process, rigorous testing, to the application of automation systems helps improve the quality and operational efficiency of substations, meeting today’s increasingly diverse and stringent power demands.

Project management process and technical standards

QuangAnhCons excels with a stringent project management process, adhering to electrical industry technical standards, ensuring progress and quality. The 2x2500kVA substation project at Nhon Trach is overseen by an experienced team to ensure each construction step is safe and effective. The 22kV electrical system is implemented by QuangAnhCons with comprehensive electrical project management measures to avoid mistakes and optimize power resources.

In the fields of construction and energy, applying international standard project management processes like ISO 21500:2012 and TCVN 11866:2017 plays a crucial role. This process typically involves five main stages that ensure the project’s efficiency and success.

1. Project Initiation This initial step involves defining overall goals and strategies. Identifying stakeholders and potential risks is essential. This is when the project charter is approved and execution strategies are determined.

2. Project Planning In this stage, detailed planning is vital. The project team needs to allocate tasks, set timelines and budgets, and conduct risk analysis to prepare appropriate response plans.

3. Project Execution This stage involves carrying out the tasks. Close monitoring is essential to address arising issues promptly and ensure quality progress.

4. Project Monitoring and Control The monitoring phase includes tracking performance, cost, and quality to ensure they align with the set plans. If deviations occur, timely corrective measures are needed.

5. Project Closure Project closure includes handing over documents and completed products, along with evaluating results and releasing resources.

Besides complying with management processes, technical standards like TCVN 11866:2017, TCVN 11868:2017 guide the construction and adjustment of technical regulations during the project implementation. This is crucial for achieving the highest management efficiency, from delineating authority and responsibility to coordinating activities transparently and effectively.

QuangAnhCons’ execution of the 2x2500kVA substation project not only demonstrates technical capabilities but also represents a long-term strategy in providing energy to large industrial zones. This project ensures investment efficiency and sustainability and stability in power supply.
