A Physical Model of Power Electronic Devices Based on Static Voltage Transducers

详细

A physical model of a thyristor ac voltage regulator with microcontroller control operating under an active-inductive load is considered. To increase the level of energy efficiency of existing electric power systems, the arrangement of the control of voltage level of supplied centers both above and below the rated value is an important condition. In existing structures, the transformation ratio generally is a constant, which does not make it possible to take into account the real irregularities of electric energy consumption. Using a transformer in a thyristor voltage regulator makes it possible to solve this problem. It shows that it may be possible to enter a preliminary stage of physical modeling of the considered process by means of creation of a program–technical complex making it possible to simulate the process of transportation of electrical energy from supply centers to consumers.
