CHARACTERISTICS OF CONTROL OF STARTING MODES IN FUEL AND ENERGY ENTERPRISES

Modern technological systems of oil refining are characterized by a large number of different types of units combined in complex technological connections with each other. In this regard, the solution to the problem of optimal control in large oil refining systems consists not only in finding the optimal modes for each technological block, but also in creating coordination links between the nodes of the technological scheme, There are certain advantages to solving the optimization problem by a complex decomposition method in complex oil refining systems. This approach simplifies the solution of the optimal control problem from a mathematical point of view, and at the same time from the point of view of organizing its solution in the process. Taking into account these features, two approaches are considered for the decomposition of systems with a complex hierarchical structure that interact with each other.
