Phase shifting transformer

Phase-Shifting Transformer is a special type of transformer used to adjust the phase angle between different branches in the power system to achieve stable operation of the power system and optimize power distribution. It plays an important role in transmission and substations of power systems.

The working principle of a phase-shifting transformer is as follows:

Phase shift transformation: Phase shift transformer achieves phase shift transformation by controlling the phase angle change in the transformer. Usually, a phase-shifting transformer has an adjustable transformation ratio, which can introduce different phase differences between the primary and secondary windings of the transformer.

Transformer construction: A phase-shifting transformer usually consists of an ordinary transformer and a phase modulation device. The phase modulation device can be a set of phase modulation transformers, or some other phase adjustment components, such as magnetic pole adjustment devices. Phase adjustment: The phase adjustment device can change the output voltage phase angle of the transformer relative to the input voltage by changing the current phase difference between the main and secondary windings. This is very useful for adjusting the phase difference between different branches in the power system to achieve optimization and stability of power distribution.

Power flow control: Phase-shifting transformers can be used to control the flow of power in power systems, especially under complex network topologies or load changes. By adjusting the phase difference of the transformer, the power flow direction can be changed, thereby adjusting the power distribution of the system. The application of phase-shifting transformers helps improve the reliability and stability of power systems. For example, using phase-shifting transformers between transmission lines can solve the problem of power flow between transmission lines, thereby reducing the load on the power lines and reducing current losses in the system.
