SYNTHESIS OF MODEL OF GAS TRANSPORTATION SYSTEM MANAGEMENT

The control system of transport of gas represents difficult human-machine system and includes gas transport resources, process of transport of gas and result of activities for gas transport. For the solution of an objective of optimization of management of system of transport of gas all set of the systems which are logging in transport of gas is classified by a sign of the processed component on three one-target classes: the power (change of characteristics of natural gas: volume of mix of gases, a chemical composition, pressure, temperature), processing (transportation of mass of mix of gases), information (receiving, processing, delivery of information on gas transport). Decomposition of system of transport of gas on the processing, power and information systems is made. The function chart of three-component model of system is made. As a basic component the complex of technical means of processing of gas (change of weight, energy and information) is allocated. For management of transport of gas of system complexes of information streams and complexes of control facilities are allocated. Interaction of active and passive systems, their influence on activity of management of transport of gas and coordination of management from Gazprom is considered. The place of dispatching management of gas transport which activity has to stimulate work of systems is defined. All set of systems of transport of gas is united by functional duties. The operational phase of system of transport of gas is presented by mathematical display of process of management of gas transport. Modeling of process of transport of gas is executed. The mathematical model of the optimized management of gas transport of system is developed. The global problem of management of transport of gas is solved by optimization of structure of management, inclusion in a contour of management of automated control systems, active participation in management of all elements of structure and observance of the established rules restrictions. The question of stability of the offered optimized control system of gas transport is considered. The analysis of reliability of the offered structure of management is made.
