Measurement method of inertia constant of power system based on large-scale wind power grid connection
After the large-scale wind power airport is connected to the power grid, the wind farm cannot actively provide inertia support to the system, resulting in a significant decline in the inertia of the power system and weakening the frequency regulation ability of the power system. In order to explore...

description | After the large-scale wind power airport is connected to the power grid, the wind farm cannot actively provide inertia support to the system, resulting in a significant decline in the inertia of the power system and weakening the frequency regulation ability of the power system. In order to explore the measurement and evaluation of inertia constant after large-scale wind farm is connected to the power grid. This paper first introduces the composition of inertia of power system at the present stage, then expounds the response process of inertia to disturbance after large disturbance of power system, and then deduces the power system model with large-scale wind power access through the analysis of traditional inertia measurement. Finally, the simulation model is used to compare the traditional measurement estimation with this paper. The maximum error is 9.18%, the minimum error can reach 2.4%, and the minimum error of the traditional estimation method can also reach 18%. Compared with traditional methods, it can be concluded that the error between the theoretical value of inertial time constant and the estimation of inertial time constant of the method described in this paper is significantly reduced. |
