Abstract

The invention provides a controller parameter setting method and device and electronic equipment, which relates to the technical field of electrical energy detection. The method includes the followingsteps: the target transfer function of a harmonic voltage source and the angular frequency of a single frequency point to be set are obtained; according to the target transfer function, the angular frequency of the single frequency point to be set and preset calculation conditions, the target proportional coefficient value of the single frequency point to be set is determined, wherein, the presetcalculation conditions include that, the integral coefficient of the target transfer function is 0, and the first amplitude frequency gain of the target transfer function away from the single frequency point to be set for the first preset angular frequency is 0dB; based on the target proportional coefficient value, the parameter root locus of the integral coefficient in the target transfer function is obtained, and the integral coefficient value of the single frequency point to be set is determined according to the parameter root locus; and according to the target proportional coefficient value and the integral coefficient value, the parameter setting result of the single frequency point to be set is determined. In this way, the controller parameters can be set quickly, which reduces thewaste of time and energy, and improves the work efficiency.

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...
