Concept of phase shifting transformer to control load sharing of parallel power lines.

Principle capacity of stage moving transformer is to control stack sharing of parallel lines autonomously of the age.

Say there are two parallel lines; 1 and 2. Line 1 has 50MW load and line 2 has 50MW. Presently say line 2 is in finished load circumstance, at that point stack in line 2 is decreased to 27MW and stack in line 1 is expanded to 73 MW. This tweaked stack sharing is finished by the stage moving transformer.

How stage moving transformer functions 

Hypothesis: 

Power move through a line is relative to the sine of the distinction in the stage edge of the voltage between the transmitting end and the less than desirable end of the line. 

So whatever we can do is to move the stage point in the sending end or accepting end of a line ; stack stream of the line will be changed thus as the heap stream of the other line additionally will be changed as they are in parallel.

Internal construction:

Phase shifting transformer working principle

In stage moving transformer there are two arrangements of transformer, one is shunt unit associated in parallel with the line and another is arrangement unit associated in arrangement with the line. The shunt unit moves the point of the power by 90°, apply this stage moved energy to the arrangement unit. At long last the arrangement unit adds the stage moved energy to the line. With the mix of association and tap change position the stage point can be altered effectively. 

Stage moving transformers are otherwise called stage point managing transformer, stage edge controller (Standard, American utilization), stage moving transformer, stage shifter (West drift American use), or quadrature promoter (quad supporter, English use)
