At present, there is an increased interest in the development of wind power engineering and its implementation into existing electrical networks in Russia. It should be noted that foreign technologies are mainly used now in Russian wind power engineering. At the same time, there are no existing normative documents that regulate the functioning of the considered wind power generating equipment with frequency converters. The investigation presents the development of a mathematical model of a wind turbine (WT) with a multi-pole permanent magnet synchronous generator (PMSG), which allows connecting to the system through a grid-controlled full-power frequency converter. The paper considers the influence of the change of operating parameters of the 110 kV electrical network on the operating parameters of the WT with the PMSG. The dynamic model of the type-4 WT is based on the classical Park-Gorev differential equations.To analyze the developed model, three different types of disturbances at the 110 kV side of the power system are simulated.
