Powerflow calculations in powersystems considering traction load
IOP Conference Series: Materials Science and Engineering, 2021 Abstract Nowadays, the negative impact of traction load on power system operation poses a serious problem that may lead to false tripping or even failures of relay protection devices and reduce the quality of electrical energy. This situation is typical for the Zabaikal power system, in which in some areas the share of electricity ...
