The article analyzes the distributed technological complexes of the Republic of Kazakhstan as objects of control and monitoring. Examples of distributed technological complexes are the oil transportation system, the mega-cities heat supply system, highvoltage power transmission system. Two distributed technological complexes were analyzed. The aim of creation and application of control and monitoring system for each complex is substantiated. A structure has been developed for constructing a control and monitoring system for the heat supply system for megacities and a high-voltage power transmission system. The generalized functional diagram of the upper level of the monitoring and monitoring system was developed.
