This paper describes the design of a new method for the minimization of STS breaking time at utility side fault. The proposed method provides reducing the fault current time use for the STS. In this paper, it is also considered with the characteristic of fault current, it can be avoided to decline the power quality damaged in the utility side fault. The simulation results show the usefulness of the method.

This paper describes a new method for the seamless operation mode transfer of a PCS. The proposed method provides reduced STS turn off time after line fault and smooth mode change between current and voltage control of the PCS. The usefulness of the method is verified through simulations.
