Abstract

The embodiment of the invention discloses a method and device for inhibiting the harmonic wave of a new energy power generation field, a controller, and a storage medium. The method comprises the steps: obtaining the rated power of each power generator set of the new energy power generation field; determining a reactive power compensation value of each power generator set according to the rated power of each power generator set; determining a reactive power adjustment quantity of each power generator set according to the rated power of each power generator set and the reactive power compensation value of each power generator set; adjusting the reactive power provided by each power generator set according to the reactive power adjustment quantity of each power generator set, so as to enablethe power factors of the power generator sets to be different during operation, and inhibit the harmonic waves of the new energy power generation field. According to the invention, the method, device, controller and storage medium can inhibit the harmonic of a grid connected point of the power generation field, and reduce the cost. Moreover, the method, device, controller and storage medium can improve the harmonic inhibition effect.

Description

technical field [0001] The present invention relates to the technical field of power generation, in particular to a method, device, controller and computer-readable storage medium for suppressing harmonics in a new energy power plant. Background technique [0002] Harmonics in power plants are mainly caused by power generation equipment, transmission and distribution equipment, and nonlinear loads in power systems. Harmonic refers to the Fourier series decomposition of the periodic non-sinusoidal AC quantity, and the obtained components other than the components with the same frequency as the fundamental frequency of the power supply are higher than the fundamental frequency. [0003] For a power plant, the harmonic current at the grid-connected point of the power plant is the sum of the harmonic currents of all generating units. Harmonic current will reduce the production, transmission and utilization efficiency of electric energy, and will have an adverse effect on the wo...
