Abstract
A new control concept for Solid State Phase-Shifter (SSPS) connected to synchronous machines is presented. This concept enables a rotary condenser to yield the active power with fast response from the flywheel effect in the rotating speed. The relations between the power and energy from the flywheel effect and the phase shift angle are presented. The experimental results using a simulator show good agreement with the theoretical energy yield.
The present study shows that the rotary condenser connected to the main network with SSPS can significantly increase the stability of the main network system. As an example, some cases of one transmission line faults in double transmission system are demonstrated. The computer simulations show a possibility of dynamic power control using the SSPS and flywheel effect of the rotary condenser as an energy storage.
