6 FAQs about [What s wrong with the box-type transformer without energy storage ]

Why do we need a transformer in a power system?

In general, in the power system, traditional transformers are used to step up/step down the voltage. But these transformers do not have the ability to compensate for voltage sag and swell, reactive power, fault isolation, and so on. But with SST we will be able to overcome these drawbacks.

Should a transformer Wye have a neutral?

Importantly, in grid-connected scenarios without storage, a wye with a neutral should be avoided on the transformer’s utility side. Such a choice runs the risk of circulating currents in the neutral, which, in turn, means more energy loss and overheating risk.

Why do we need a solid-state transformer?

Because the solid-state transformer (SST) can solve these problems in the distribution network not only by facilitating controlled bi-directional distribution of active and reactive powers, but also can provide a robust DC bus to isolate the disturbance on both sides of the transformer. 2

What are the advantages and disadvantages of a conventional transformer?

Conventional transformers provide a cheap and efficient method to convert voltage and insulation levels. Some advantages of these transformers are: Despite the widespread use of this equipment in the power system, it has the following disadvantages: Any unwanted changes in the input directly affect the output voltage.

How intelligent transformers work?

It should be noted that intelligent transformers by applying telecommunication links constantly monitor the grid, and in case of any disturbance in the grid, immediately operates in islanding mode, thus ensuring the continuity of load service, which will increase the reliability, stability, and efficiency of the system.

Are solid-state transformers a suitable alternative to conventional transformers?

In this regard, solid-state transformers have been proposed as a suitable alternative to conventional transformers. Solid-state transformers are among the equipment based on power electronic converters that in addition to better performance than conventional transformers provide a variety of other services.
