Analysis of nonlinear load influence on operation of compensating devices

[摘要] The paper presents the results of studies to detect the location of the high harmonics distortion source relative to the connection point shared by consumers. The developed method is rather simple to use at an industrial enterprise, since it does not require the connection of additional measuring devices and is based on the assessment of the capacitor banks overload with antiharmonic reactors depending on the system resistance. The change of the system resistance can be carried out by switching branches on the windings of transformers and assessment of capacitor banks overload via using built-in reactive power controllers.
