DEVELOPMENT OF THE SCHEME AND RESEARCH OF THE MATHEMATICAL MODEL OF THE VOLTAGE REGULATION DEVICE ON THE TRANSFORMERS WITH SWITCHING WITHOUT 10/0,4 kV EXCITATION
Abstract:
Providing the necessary quality of voltage is an indispensable condition of production efficiency. Local voltage regulation gives the chance of independent regulation and support of voltage levels on separate lines according to change. It is proposed voltage control device, which use gives the chance significantly reduce generation of higher harmonics in an electrical network. Mathematical model of the device of regulation of voltagewith functional flowchartpresented. In the environment of visual programming of Simulink Matlab the mathematical model is worked out. Researches of the device on the transformer with switching voltage without excitation conducted at electric remoteness with active and inductive loading and during asynchronous device start. Researches showed efficiency and effectiveness of the device the use of which gives the chance to stabilize voltage according to the time of self-start of the group of electric motors and other difficult operating modes.
