Microprocessor excitation systems of electromechanical complexes with synchronous motors

Article preview

Perfection of systems of excitation is defined both actualization of known requirements, and occurrence new. We shall note the following: increase of the entrance moment, increase in dynamic stability, decrease in losses, maintenance of requirements on quality of the electric power networks of feed, group management and regulation, a mode of operation with a minimum level of service. Performance of these requirements with a necessary level of efficiency is provided with application of the power keys operated by a voltage (IGBT, IGСТ) and microcontrollers. New electronics allows to maintain the equipment with a minimum level of service, but generates a new problem of replacement of accessories at long operation. For example, alternation of generations of microcontrollers demands drawing up and debugging of the new program.

Control of synchronous drives of stationary plants during start-up

Article preview

The necessity of forming the specified starting characteristics of stationary plants of mining enterprises with synchronous drive of medium and high power is shown. The synchronous motor with excitation system with two-way converter is considered. This excitation system meets the technical requirements for the considered types of drives. When starting and self-starting the motor, the bilateral converter is used as an inverter, and during synchronous operation as a controlled rectifier. At the same time, its operating mode depends on the voltage level in the supplying network and the value of the current induced in the field winding of the motor. It seems necessary to consider the issues of stable operation of the two-way converter in the inverter mode and to investigate the motor starting characteristics with this system in order to obtain the corresponding analytical dependences and calculation methods. Idealized dependences of the maximum value of the inverted current on the control and commutation angles and the parameters of the power transformer were obtained. When analyzing these dependences, it is determined that in real conditions, the maximum value of the control angle at the same parameters of the power transformer and the value of current i f is less than in the idealized ones.
