Abstract

The invention provides a mobile terminal based power system stabilizer (PSS) parameter setting method and apparatus. The parameter setting method comprises the steps of obtaining uncompensated phase frequency angles of a generator set under multiple set phase-frequency characteristic frequencies; setting a common identifying code for the uncompensated phase frequency angles for each generator set according to the multiple set phase frequency angle ranges corresponding to each set phase-frequency characteristic frequency; establishing a uncompensated phase frequency characteristic data-PSS parameter corresponding library by the on-duty generator set PSS data or the generator set PSS test simulation data according to a PSS model corresponding to an excitation system of the generator set; finding an index code that is uniquely corresponding to the identifying code from all index codes of the uncompensated phase frequency characteristic data-PSS parameter corresponding library; and determining the PSS parameter setting data of the generator set according to the PSS parameters in the uncompensated phase frequency characteristic data-PSS parameter corresponding library corresponding to the found index code. According to the mobile terminal based PSS parameter setting method, the PSS parameter setting working process can be simplified.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method and device for setting PSS parameters of a power system stabilizer based on a mobile terminal. Background technique [0002] With the development of modern power systems, weakly connected grids, long-distance transmission lines, heavy system loads, and a large number of fast excitation systems in the grid have become the main features. These factors reduce the damping of the power system, which greatly increases the possibility of low-frequency oscillations in the power system and has seriously affected the stable operation of the power system. Power System Stabilizer (PSS) is currently the most effective way to suppress low-frequency oscillations. measures. [0003] In order to ensure that the PSS can work safely and reliably, the parameters must be adjusted before the PSS is put into operation, so as to obtain the ideal damping effect. At present, the field t...
