Differential transmission of evolution measures in SCADA systems
J. Luque · IEE Proceedings - Generation Transmission and Distribution · 1994
The problem of modelling the evolution of the measures (analogue values) acquired by energy control centres, to find a statistical predictor for future values is discussed. The prediction technique obtained is used to reduce the number of bits required to transmit an analogue value from a remote terminal unit (RTU) to the relevant control centre. Significant improvements have been obtained with reduced computational effort.
