This paper concerns two power stations using a combined thermal cycle where the heat of the exhaust gases is recovered in a boiler which delivers superheated steam to a steam turbine. After a description of the start-up process, it deals with a few typical problems which had to be solved in working out the automatic and semi-automatic control systems. It also describes auxiliary elements such as the control panel and the supervisory system. The choice between automatic and semi-automatic plants is discussed.

The article is devoted to the development of modern models and algorithms for information processing for the prediction, diagnosing and maintenance tasks of inter-element interaction in automatic control systems of aviation gas turbine engines. Considered the model of inter-node interaction with the definition of power active points and their neural structures with visualization in the form of scalogramm. Presented a graph of changes the power node characteristics of the automatic control systems of gas turbine engine and the distribution histograms of practically normal states and faults with defect properties on the scale of confidence coefficients based on the control algorithm the prediction and diagnostics processes according to the data of the system survey.The decision support system during the research process has two stages of functioning:1) at the stage of prediction and diagnostics, the measurement of the power characteristics of the active interaction points is determined, and corresponding elements of the models are taken into account the power states formed on the nominal energy state of the nodes;2) at the stage of maintenance and repair, while observing the painted nodes, determine the type, intensity and duration of influence in order to normalize the power of the nodal active points of interaction (to bring the state to a dark brown colour). At the same time, the dynamics of the correction process is well traced, visually visible to which accompanying situations is directed the impact and how it will affect the functioning of the linked nodes and /or systems.During the developing an appropriate system of inter-element interaction in automatic control systems of gas turbine engines, it is possible to receive an educational and control sample to support decision-making, check the reliability of the operation of the received rules, and if necessary, a training procedure can be implemented to improve the accuracy of the classification by training and control samples.The developed rational technology of building the architecture of nodes in the automatic control systems of aviation engines will create high-performance systems of a new generation with a flexible, easily variable structure, increase reliability and durability of operation of automatic control systems of aviation engines.

The article explores the possibilities of building automatic control systems for gas turbine power plants. The use of the principles of adaptive control with a reference model and a signal effect is being studied. As an adaptation method, a method based on the Lyapunov function is used, in order to reduce the time for searching for an extremum. There is a need to ensure the specified indicators of electricity the quality in a constantly changing electrical load and changes in operating modes of the power plant in gas turbine units. The article presents a model of a gas turbine installation for the study of adaptive control. It is shown that the improvement of one coordinate is possible to obtain due to some deterioration of the other coordinate. For further study of this problem, a simplified second-order dynamic model has been constructed. With the help of such a model, complex studies of various stages of adaptive control were carried out. Results were obtained by varying the parameters of adaptive control and simulation parameters. The research results are designed to find the optimal ratios of adaptive automatic control systems parameters for power industry gas turbine plants.
