Abstract:

In order to facilitate the selection of devices, the main power quality problems caused by common special loads and the application of dynamic reactive power compensation devices are reviewed. The basic principles and composition types of dynamic reactive power compensation devices (SVC, SVG) are analyzed. Their characteristics and applications are summarized. The simulation control model of SVC and SVG in PSD-BPA simulation software is introduced in detail. Through the simulation analysis of a project case of weak grid, the results verify that the voltage stability is mainly related to the capacity of dynamic reactive power compensation device, and in the case of certain capacity, voltage fluctuation can be reduced by optimizing control parameters.
