Anton G. Merkulov , PhD, SMIEEE, is lead of the PLC research team at the Almaty University of Power Engineering and Telecommunications, Almaty, Kazakhstan. Dr. Merkulov has more than 12 years of experience in telecommunications for power grid companies, and is the author of two books (in Russian) and more than 30 papers about high voltage PLC/DPLC. He is a member of the Work Group RG2 "Telecommunications for Power Grids" of the Russian National CIGRE Study Committee D2.
Yuri P. Shkarin , PhD, has developed a theoretical basement for calculation of parameters that determine the conditions of waves propagation along high voltage electric power transmission lines. Applied to power line carrier communications these parameters are HF path attenuation, group time delay, input impedance, return loss. The study of waves propagation processes along non-homogeneous multiconductor power lines and development of calculation methods have been carried out using modal theory, theory of matrices and theory of multiple grids.
Dr. Shkarin pays great attention to experimental testing of the results of theoretical studies. He developed a way to measure the modal parameters of multiconductor power lines by open and short circuit method. The experimental determination of HF paths frequency characteristics along electrical power lines with voltage class from 110 up to 1150 kV and modal parameters of these paths has been carried out with his direct participation.
Together with A.A. Filippov developed special software WinTrakt and WinNoise for calculation of HF paths parameters for power line carrier channels. These programs are used worldwide in such global companies as Siemens AG, ABB, General Electric, and the Israel Power Grid Company, as well as throughout Russia and Commonwealth of Independent States (CIS) countries.
Dr. Shkarin is author and co-author of 7 books (in Russian) and more than 90 articles about high voltage PLC. Most of the research was conducted by Dr.
