Abstract

The invention provides a controller parameter setting method, device and electronic equipment, and relates to the technical field of electric energy detection. , the angular frequency of the single frequency point to be adjusted and the preset calculation conditions to determine the target proportional coefficient value of the single frequency point to be adjusted; wherein, the preset calculation conditions include that the integral coefficient of the target transfer function is 0 and the target transfer function is at a distance to be adjusted The first amplitude frequency gain at the first preset angular frequency of the order frequency point is 0dB; according to the value of the target proportional coefficient, the parameter root locus of the integral coefficient in the target transfer function is obtained, so as to determine the integral of the single frequency point to be adjusted according to the parameter root locus Coefficient value: Determine the parameter tuning result of the single frequency point to be tuned according to the target proportional coefficient value and integral coefficient value. In this way, the rapid setting of the controller parameters can be realized, the waste of time and energy can be reduced, and the work efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of electric energy detection, in particular to a controller parameter setting method, device and electronic equipment. Background technique [0002] A large number of nonlinear and impact loads (such as high-power power electronic equipment, electrified railways, large-scale metallurgical equipment, etc.) and wind energy, photovoltaic and other new energy power plants or distributed power sources are connected to the power grid, resulting in serious harmonics in the distribution network question. Harmonic problems will lead to abnormal dynamic and thermal stability of power equipment, lead to primary and secondary equipment heating, vibration, noise and other obvious causes of influence, and will also cause primary and secondary equipment to malfunction and refuse to operate The phenomenon of hidden causes such as damage and damage is increasing. These impacts not only cause major economic losses, but also...
