Khokhlov V. Remote control systems of electrical energy converters in noisy environment

Object of investigation: transmission of remote control signals for energy converters over local power-lines in conditions of interferences. Aim: development of expedients and systems of noise-immunity remote control for energy converters over power-lines in conditions of interferences from this energy converters. Methods: spectral transformations of discrete signals, methods of the coding theory, the communication theory, the electromagnetic compatibility theory and methods of mathematical modelling. Principal results: transformation of the discrete signal at oriented basis to enhance a noise-immunity of signal transmission in systems of converters remote control over power-lines for the first time is used. This allows to enhance performance in terms of error probability, to enhance a number of channels in comparison with existing systems and to develop on this basis a method of the adaptive transmission. The method of automatic synchronization of a signal transmission system of remote control which does not require usage of a central synchronizing pilot-signal is offered. This considerably simplifies a remote control system of energy converters.
