A Direct Method for Searching Power System Second Order Resonance Point

Abstract:

The dynamic characteristics of the power system will be a sharp deterioration near the second order resonance point. In-depth study of the Power system dynamic characteristics near the second order resonance point, and then how to cause the dynamic characteristics of the system worse at the second order resonance point near the stable boundary, need to quickly search system of second order resonance point. Based on the principle of minimal expansion system method, this paper presents the direct method for search the second order resonance point in power system. For the N dimensions differential dynamic system was established in the 4N+4 dimension expansion equations. The power system second order resonance point search is changed into expanding equation fixed point solution. Significantly reduce computational load, improve the search accuracy for solving second order resonance point calculation. For in-depth study of power system dynamic characteristics near the second order resonance point have a certain value.
