SIPS development method and busbar splitting scheme supported by PMU technology

Research presented in this paper is part of the idea for developing smart transmission grid (STG) supported by system integrity protection schemes (SIPS) based on phasor measurement unit (PMU) technology. The main objective of SIPS is to monitor the state of power transmission networks in real-time and if needed in emergency cases to undertake advanced actions. Contribution of this paper is new SIPS development method and busbar splitting scheme supported by synchronized phasor measurement technology (SPMT). Proposed method gives detail description how to develop SIPS through several steps, as well as the simulation of their operation. It is based on heuristic approach and detailed AC power flow analysis. Busbar splitting scheme is described through its activity and initiation conditions in this paper. Initiation model is given in the form of graphical representation with its releasing and blocking conditions. Developed method application to the IEEE 14 busbar system is given after its defining. Carried out tests show that developed method can mitigate potential overloads of the observed network part by using suggested busbar splitting schemes.
