Problems solved by technology

In order to ensure the effective and stable operation of the power system, it is obvious that the influence of harmonics on the power system needs to be suppressed. The current harmonic suppression methods must take the harmonic source as the prophetic information, but the harmonic sources that affect the normal operation of the power system are rarely obvious. nature, more harmonic sources are unknown

Abstract

The invention discloses a deployment method of a harmonious wave detector of an electric power system. The deployment method comprises steps of step 1, carrying out initialization; step 2, optimizing optimization searching; and step 3, selecting a theta(1) with the smallest F(1), if the element in the theta(1) is 1, deploying a harmonic wave detector for a corresponding bus, and if the element in the theta(1) is 0, not deploying a harmonic wave detector for the corresponding bus. Compared with the prior art, the deployment method is advantageous in that the method is simple; the quantity of the deployment detectors is the smallest; and the most redundancy can be detected.

Description

technical field [0001] The present invention relates to the field of electric power systems, and specifically refers to a method for deploying harmonic detectors in electric power systems based on a binary artificial bee colony optimization mechanism. Background technique [0002] In recent years, due to the integration of new energy into the large power grid and the emergence of nonlinear loads, the power system will also be "polluted" like the natural environment, that is, harmonic interference. Harmonics will not only affect the normal operation of the power system, but also cause power system failures. In order to ensure the effective and stable operation of the power system, it is obvious that the influence of harmonics on the power system needs to be suppressed. The current harmonic suppression methods must take the harmonic source as the prophetic information, but the harmonic sources that affect the normal operation of the power system are rarely obvious. Sexually, ...
