Dynamic System Equivalents for Transient Stability Studies
It is difficult to perform the dynamic analysis on large scale power systems within a desirable time frame. Most utilities therefore resort to reduce the scale of power system by representing the external system using an equivalent network. This project proposal in conjunction with Manitoba HVDC Research Centre aims to develop simulation based methods complemented with modal methods to obtain a dynamic system equivalent for the external power system. The main task of this technique is to obtain the actual system responses to applied disturbance and identify the parameters of the external equivalent circuit. The proposed method will help utilities to generate an equivalent circuit to capture the impact of the external system, which will enable dynamic simulation of large power systems with faster computational time.
