摘要：Power flow in elements of the network causes voltage drops in these elements.Therefore,in order to ensure the proper voltage of electric power delivered to consumers it is necessary to regulate voltage in power engineering grids.The article presents voltage requirements in power engineering grids,the impact of regulation on losses in distribution lines and various criteria for optimizing voltage regulation.Depending on the adopted criteria,indications for tapping switch settings in transformers and input voltage may differ for various lines or even be quite the opposite.
