Substation Expert Quanganhcons: Comprehensive and Effective Solutions

Quanganhcons stands out in the field of designing, constructing, and installing substations in Vietnam, particularly strong in modern technology and diverse services.

Advanced Technology in Substation Design

Quanganhcons applies automatic control and monitoring technology via SCADA in substation design, allowing for remote management and operation. This not only helps reduce costs but also enhances the safety and stability of the electrical system. This integration is particularly beneficial for ensuring performance and reliability for 35kV substations.

In the power transmission and distribution system, substations play an essential role in voltage conversion and system stability. Today, with the urgent need to improve operational efficiency, advanced technologies have been integrated into substation design. One of these solutions is the use of digital technology through Digital Substations. By replacing traditional equipment with intelligent measurement and control devices, these substations not only enhance measurement accuracy but also facilitate remote monitoring, reducing maintenance costs.

Integrating the SCADA system is another significant advancement. SCADA systems enable remote management of devices, coupled with IoT technology to collect real-time data, thereby ensuring stability and effectively forecasting issues. In modern design, compact substations are favored for their ability to save space and flexibility during installation, especially in urban areas.

Advanced insulating materials such as polymer and composite are also widely used to increase lifespan and reduce fire hazards. Simultaneously, AI support in substations helps optimize maintenance schedules, minimize errors, and enhance operational efficiency.

Additionally, environmentally friendly design trends (Green Substations) are becoming increasingly popular. Using green designs and renewable energy not only reduces energy consumption but also reduces greenhouse gas emissions, while oil-free transformers minimize the risk of toxic chemical leaks.

Faced with current challenges such as high safety requirements and integration of new systems with old systems, solutions like design optimization based on digital simulation and choosing standardized equipment have been implemented to cope and maintain the sustainability of the power system.

Application and Efficiency of Substations

Substations provided by Quanganhcons are widely applied in large industrial zones like Dung Quat Economic Zone. These stations not only ensure a stable power supply but also meet complex energy demands, enabling enterprises to operate continuously and more efficiently.

The substation is a crucial link in the power system, responsible for voltage conversion to serve safe and effective power transmission and distribution. In the power system, substations have various rich and diverse applications.

Applications of Substations

• Transmission Substation: Specializes in reducing voltage from ultra-high levels to high or medium levels to minimize energy loss during long-distance transmission. This optimizes system efficiency.
• Distribution Substation: Converts voltage from high or medium to low levels, serving electrical distribution to households, businesses, and residential constructions.
• Industrial Substation: Provides suitable voltage for equipment and production lines in factories and enterprises, playing an indispensable role in ensuring production efficiency.
• Urban Substation: Designed to supply energy to urban areas, commercial centers, and densely populated residential areas, meeting high electricity consumption demands.
• Agricultural, Remote Area Substation: Serves rural, mountainous, and island areas that are difficult to access, contributing to local socio-economic development.
• Backup Substation: Ensures continuous electricity supply during incidents or maintenance of other stations, avoiding interruption of operations.

Efficiency and Benefits of Substations

• Reduce Energy Loss: Substations play a crucial role in appropriate voltage transformation, helping to minimize power loss and improve energy supply efficiency.
• Stability and Power Source Protection: Isolation transformers and devices in substations protect electrical equipment from overvoltage or undervoltage incidents, enhancing safety for both industrial and residential power systems.
• Ensure Safety and Continuous Operation: The application of advanced technologies such as SCADA, Thermographic UAV helps timely detect incidents, minimizing accident risks and power interruptions.

Application of Advanced Technology at Substations

• Remote Monitoring by SCADA: SCADA technology is a useful solution for collecting, monitoring, and remotely controlling devices in substations, thus helping to operate more efficiently, reducing errors, and saving costs.
• Using UAV with Thermal Sensor Cameras: This technology helps early detect abnormal thermal points, promptly handling incidents, especially in challenging terrain areas.
• Digital Transformation and Management Software: Use specialized software to manage techniques, testing, safety, and power measurement, enhancing accuracy and automation, reducing reliance on manual labor.

In the current context, substations are not only a technical connection point but also the backbone of the power system. The application of advanced technology is helping substations continue to improve monitoring capabilities and operate more intelligently, ensuring a stable and reliable power source for users.

Safety Standards and Substation Maintenance

Quanganhcons strictly adheres to technical and safety standards in fire prevention and equipment protection. This not only protects assets but also contributes to maintaining sustainable operation for substations. Quanganhcons also provides operational support and maintenance services to ensure system stability.

Fire Prevention Safety Standards and Design

Ensuring fire prevention safety in substation design is extremely important. Stations need to be built with safe spacing between equipment using fire-resistant materials, proper ventilation, and escape routes. Equipping essential devices such as fire extinguishers, automatic fire detection systems, and lightning protection systems is indispensable to ensure optimal performance.

Electrical Safety Standards and Equipment Arrangement

Safety barriers and standard equipment arrangement are indispensable elements to ensure electrical safety in substations. Transformers and electrical distribution devices must have barriers ensuring safe distances. Circuit breakers, fuses, and relays must have clear schematic diagrams, numbered for easy technician manipulation. Especially, the switch cabinet needs to meet the suitable protection index (IP) for the working environment and equipped with a roof to prevent water and dust.

Operation and Maintenance Process

A standard substation operation process must include regulations on incident handling and routine maintenance. This requires a team of staff trained deeply in fire prevention and electrical safety. Periodic anti-incident drills will help staff always ready in emergency situations.

Technical Standards for Protection and Grounding

The ground resistance must not exceed 4Ω, which is an important technical requirement for maximum safety. The short-circuit current protection system needs to exceed 3 times the rated current of the disconnector to automatically cut off during incidents. This requires the system to be established according to strict national technical standards and indicators.

Quanganhcons not only provides advanced technical solutions that save investment costs and enhance operational efficiency but also offers comprehensive maintenance support, ensuring safety and sustainability for the power system. With these solutions, businesses can confidently develop long term.
