description: The purpose of the final qualification work is the design of relay protection of the station equipment unit. The unit consists of a turbo generator of the brand TVV-320-2 with a capacity of S = 377 MBA and a rated voltage of Unom = 20 kV, as well as a block power transformer TDN-400000/110 with a capacity of S= 400 MBA and a rated voltage on the high and low sides of Uvn = 500 kV and U_Nn = 20 kV, respectively. Also, when performing this work, the layout of relay protection devices for measuring current and voltage transformers was designed. In accordance with the adopted main circuit and the choice of the main power equipment, short circuit calculations were performed at various points of the block. For a detailed calculation, the substitution schemes of the forward, zero and reverse sequences were performed and reflected in the work. Based on the regulatory and technical documentation and the requirements for the reliability of the RPA, the main functions for protecting the generator and transformer of the block were determined, as well as technical solutions for protecting the block of manufacturers from various countries were considered and described in detail. Also, an important part of the work was done in the Simulink program. To study the behavior of RPA devices, a mathematical model was created of one of the blocks that supply electricity to a 500 kV switchgear. The model allows you to evaluate various transients in the circuit and analyze the operation of the block protections. Modeling of three-phase, two-phase and single-phase earth short circuits at various points of the model is carried out and values of currents, voltages and their vector diagrams are obtained.
