How can transformers achieve free capacity increase? Today, the editor of Bonada will reveal this mystery for you.

When it comes to transformer capacity increase, many people may first think of peak-valley arbitrage. In fact, in addition to the peak-valley arbitrage function, energy storage cabinets have many other functions. For example, in actual electricity consumption scenarios, there are situations where electricity consumption is low at night and high during the day.

When the transformer surplus is not enough to support the electricity consumption during the day, it is usually considered to statically increase the capacity of the transformer, that is, directly apply to increase the capacity of the transformer. However, this method will incur design costs, equipment costs and construction costs, and the total costs may be as high as hundreds of thousands of yuan.

With the help of energy storage cabinets, the problem of dynamic capacity increase can be solved during the low electricity consumption period at night. When electricity consumption is low at night, the energy storage cabinet is fully charged; during the day, the load power consumption is monitored in real time through a bidirectional current sensor, and dynamic adjustment is performed according to the load power.

When the transformer is close to full load operation, the energy storage cabinet begins to discharge to supplement the insufficient power supply of the transformer, thereby achieving dynamic capacity increase. It is worth mentioning that in the process of dynamic capacity expansion, peak-valley arbitrage can also be carried out simultaneously. Isn't it clever?
