With the rapid development of urban economies, the imbalance between energy supply and demand has become increasingly significant. In power distribution systems, it is crucial to implement energy-saving measures and advanced technologies. Transformers, as the core components in power distribution, play a vital role in achieving energy efficiency. Optimizing their operation is one of the top priorities in reducing energy consumption within the grid system. Implementing effective strategies to minimize transformer losses is essential for improving the overall performance of power distribution networks. First, let's explore the key technologies for energy saving in transformers. 1.1 Using Advanced Materials The use of new materials in transformer manufacturing can significantly improve efficiency and reduce energy loss. For instance, oxygen-free copper is widely used due to its low resistance and high conductivity, which helps reduce internal losses in the transformer coils. This material also enhances the transformer’s ability to withstand short circuits. Another innovative material is amorphous alloy, which is used in the core of distribution transformers. It minimizes electromagnetic losses, contributing to better economic performance and lower energy consumption. 1.2 Installing Automatic Voltage Regulators Transformer losses are closely related to the voltage levels in the distribution network. To optimize this, automatic voltage regulators can be installed to maintain stable output voltages. These devices adjust the transformer’s ratio based on input voltage, ensuring that the output remains within a 3% range of the normal value. By doing so, the system can operate more efficiently, reducing unnecessary energy waste and improving overall stability. 1.3 Adopting an Economical Operation Mode The way a transformer operates has a major impact on its energy consumption. Traditional operation modes often lead to inefficiencies and higher losses. To address this, modern techniques such as reactive power compensation are employed. By installing parallel capacitors at low-voltage points, the system can compensate for inductive loads, improving power factor and reducing losses. Additionally, balancing the three-phase load is critical, as unbalanced loading can cause voltage fluctuations and increase both transformer and line losses. Proper load balancing ensures smooth and efficient operation. Second, let's look at practical measures for energy-efficient transformer operation. 2.1 Selecting Energy-Efficient Transformers When designing and selecting distribution transformers, it's advisable to choose models with low loss rates and high efficiency. For example, the S11 and S13 series transformers are known for their energy-saving performance. Compared to older models like the S9 series, they offer up to 30% lower no-load losses and 40% less no-load current. Their strong overload capacity makes them ideal for systems with fluctuating loads, offering greater flexibility and long-term cost savings. 2.2 Operating Multiple Transformers Together As distribution networks grow, the need for flexible and efficient operation increases. Operating multiple transformers together allows for optimized scheduling based on real-time load conditions. Each transformer has its own no-load and load losses, which vary nonlinearly with the load. By calculating the optimal load point and using the most suitable number of transformers, the system can avoid inefficient operations like “large horse-drawn car†scenarios. This approach improves reliability, safety, and energy efficiency across the network. 2.3 Balancing Load Distribution Unbalanced load distribution among the three phases can lead to increased losses and instability. By adjusting the load ratios and ensuring balanced operation, the system can run more smoothly. This not only reduces energy consumption but also extends the lifespan of the equipment and improves overall system performance. Implementing smart load management techniques can further enhance these benefits, making the entire power distribution system more sustainable and efficient.
