1. Accelerate power distribution transformer Upgrades
The primary step in reducing power distribution transformer energy consumption is to phase out a significant number of old, high-energy-consuming power distribution transformers in the system, particularly in low-voltage distribution networks where many inefficient power distribution transformers continue to operate. Investment should be increased to promptly replace them with low-energy, high-efficiency modern power distribution transformers, such as amorphous alloy core power distribution transformers or series power distribution transformers with wound iron cores. The use of these new, eco-friendly, and low-consumption power distribution transformers will yield substantial energy-saving benefits for the power grid. For instance, power distribution transformers utilizing a wound iron core structure can reduce no-load losses by approximately 10%-25%.
2. Achieve Economical power distribution transformer Operation
To optimize the load factor for power distribution transformer operation, considering the pattern of changes in the power grid's load, it is crucial to adjust the grid's load in a timely manner, aiming for operation within the economic range, ideally around 85%-95%. Additionally, optimizing the operation mode when multiple power distribution transformers operate in parallel, with nearly equal active power, can achieve the best load for the power grid and, consequently, promote economical power distribution transformer operation.
3. Optimize Power Grid Operation
The layout of the power grid and the choice of supply radius have a significant impact on power distribution transformer operation. To achieve energy savings for power distribution transformers, it is essential to consider regional power grid characteristics and plan design accordingly. During the initial layout and planning of the power grid, it is important to optimize the allocation of load centers, place power distribution transformers as close to load centers as possible, and enhance network connections to improve power supply reliability. In practice, efforts should be made to radiate power sources to the surrounding areas, thereby reducing the supply radius. This can be achieved by increasing the cross-sectional area of conductors to distribute and reduce losses. Additionally, maintaining three-phase balance during load operation is vital to avoid increased power distribution transformer losses caused by reactive power, which can affect the economical operation of power distribution transformers.
4. Actively Adopt New Technologies
Furthermore, with the advancement of power grid technology, various energy-saving technologies can be applied in the field of power distribution transformer energy conservation. One such method is harmonic reduction, which has gained widespread application in recent years. This involves the installation of active filters on power distribution transformers to compensate for load harmonics and reduce harmonic losses on the power distribution transformer. According to statistics, the use of active filters can reduce losses in each power distribution transformer by approximately 10%, resulting in significant energy-saving benefits.
