Controlled phase shifters model for power grid operating modes calculation

This paper presents controlled phase shifters (CPS) unified model (UM) for power grid modes calculation. Internal different topologies of CPS which affect the parameters of the UM are considered. Parameters of UM for various CPS topologies are calculated and analyzed. The influences of different topologies and control on transfer functions of CPS are investigated. The implementation of UM for calculation of operating modes of a three-phase power grid with CPS based on thyristor controlled phase angle regulator (TCPAR) is presented. CPS impacts on operation modes of power grid are analyzed.
