NTC-10.72 “Simulation of transitory processes in electricity power supply systems”

Br0.00

The educational laboratory stand is designed for use as training equipment in higher education institutions, secondary specialized schools, and vocational-technical colleges during laboratory and practical lessons on studying the operating modes and static stability of a basic electrical system using an electrodynamic model. Additionally, it facilitates analysis of the impact of various types of short circuits on the dynamic stability of the power transmission system. The asynchronous mode of system operation is examined, and characteristics of the mode of a simple system consisting of two stations of equal capacity are recorded.

Structurally the stand consists of two parts: 
  • body in which electric equipment is mounted, power module, electric cards, front panel and desktop of integrated table;
  • a machine unit with one synchronous generator, one asynchronous electric motor with a squirrel-cage rotor, and an optical speed pick up.

The training system is supplied with:

  • a software, which provides:
    • studying theoretical materials;
    • initial verification and consolidation of the acquired knowledge with tests included in the program (the teacher has the ability to edit tests and create new ones);
    • carrying out laboratory work with a detailed step-by-step description of the experiments. Students assemble the circuit on the stand panel, according to the specified parameters, carry out experiments according to the instructions, register their observations and measurements in the appropriate fields and tables of the program. On the basis of the data obtained, by the software proceeds to subsequent calculations and the construction of graphs (depending on the content of the laboratory work);
    • after each experiment, an individual final report on the laboratory work is generated, saved in the .doc format.
  • a set of methodological and technical documentation intended for the teaching staff.
