Realization of steady state modeling of unified power flow controller in a control system

The basic structure of UPFC is introduced in combination with demonstration projects of the unified power flow controller in China. According to the actual construction of dispatching control system, the realization of the steady state physical model and measurement acquisition model of the unified power flow controller in dispatching control system are designed. The mathematical models of UPFC based on equivalent power injection are applied to on-line advanced application softwares of dispatching control system such as state estimation, dispatcher power flow and static security analysis. The implementation methods of these advanced application softwares considering UPFC are proposed. Finally, it introduces the specific implementation of the UPFC model and graphics sharing between superior and subordinate dispatching centers and within dispatching centers based on CIM/E and CIM/G standards. Through the practical application of D5000, the effectiveness and practicability of this method are proved.
