Method for increasing reliability for transmission state of power equipment energy

In this paper the problems of transmitting trustworthy monitoring and control signals through the communication channels of sophisticated telemechanics systems using the IEC 60870-5-101 (104) are debated (104). Mathematically justified discrepancy between concepts of "information veracity" and "information protection from noise in communication channel" is shown. Principles of combined encoding ensuring high level of veracity of systems intended for energy supply are proposed. The paper also presents a methodology for estimating the level of veracity of information signals of systems used in telemechanics and the results of experimental studies of proposed encoding principles effectiveness.
