A new method for the measurement of the rotor angles and the phasors of power systems is proposed in this paper. Based on this method, the angle and phase measurement unit (APMU) has been developed. The rotor angles can be measured directly with speed signals of generators instead of being calculated with the power equations of the generator. Hence, the measurement precision of the rotor angle is...
An unified power flow controller (UPFC) is a multi-input and multi-output (MIMO) multivariable controller and dynamic interactions are found among its multiple control functions. Focus of study in this paper is to investigate two cases of UPFC control interactions: (1) interactions caused by inappropriate setting of UPFC controller's parameters; (2) interactions irrelevant with setting of UPFC controller's...
