Analysis and Optimization Suggestions for the Economic Operation Mode of Power Transformers

1、 The Importance of Economic Operation of Power Transformers

Power transformers are the main equipment in the power system, playing a crucial role in the transmission, distribution, and utilization of electrical energy. Its economic operation not only affects the efficiency of power grid transmission and distribution, but also directly relates to the operating costs of power enterprises. Therefore, it is crucial to analyze and optimize the economic operation mode of power transformers.

2、 Factors affecting the economic operation of power transformers

1. Load situation: including light load operation and overload operation. During light load operation, the transformer capacity is not fully utilized, resulting in resource waste; Overloading operation can lead to increased transformer losses and even cause malfunctions.

2. Unbalanced three-phase load: When the three-phase load is unbalanced, the active power loss of the transformer will significantly increase, and it will also cause an increase in low-voltage line loss.

3. Power factor: Some companies idle their power factor compensation devices, resulting in a low overall power factor of transformers and affecting economic operation.

4. Transformer type and status: Some power grids have old high energy consuming transformers, resulting in high line loss rates. In addition, insufficient self switching devices and frequent switching of transformers can also affect their economic operation.

3、 Optimization suggestions for the economic operation of power transformers

1. Reasonably adjust the load: flexibly adjust the capacity and operating status of the transformer according to the load situation to ensure that it operates within the optimal load range. For transformers operating under light load, appropriate adjustments can be made during low load seasons to improve capacity utilization.

2. Balancing three-phase loads: By optimizing the load adjustment between phases, the imbalance of three-phase loads can be reduced, thereby reducing the active power loss and low-voltage line loss of transformers.

3. Improve power factor: Actively utilize power factor compensation devices to enhance the overall power factor of transformers, in order to improve their economic operation.

4. Updating and maintaining equipment: Gradually phasing out old high energy consuming transformers and adopting high-efficiency energy-saving transformers. At the same time, strengthen the maintenance and repair work of transformers to ensure that they are in good operating condition.

5. Intelligent management and control: Introduce advanced control strategies and technical means, such as intelligent scheduling, adaptive control, etc., to achieve intelligent management and control of transformers, further improving their operational efficiency and stability.

In summary, by adjusting the load reasonably, balancing three-phase loads, improving power factor, updating and maintaining equipment, and implementing intelligent management and control measures, the economic operation mode of power transformers can be effectively optimized, operating costs can be reduced, and the energy efficiency and stability of the power system can be improved.
