- W2955182458 abstract "Mathematical models of particular parts of a turbine control system are presented, including also the electrohydraulic system for the positioning of the gate regulating ring. On the basis of the mathematical model of the entire system, using the pole placement method, the synthesis of the hydropower unit speed and power is done. As a result of the synthesis, analytical expressions are obtained. Using these expressions it is possible to calculate PID controller parameters (for speed control) as well as PI controller parameters (for power) in a wide operating range of the power unit (gate opening, head, speed). The simulation results and the results measured in the real plant are presented. Some of the methods for turbine controller designing available in literature are compared with the results presented in the thesis. Attention is also given to fault detection and isolation in the turbine control system. An idea for the realisation of such a diagnostic system is given, and one of the possible faults occurring in the electrohydraulic system is considered in detail. Also, the algorithm for the detection of such a fault is presented. The results have been proved by simulation on the basis of the signals measured in the cases of occasional failure occurrence in that part of the system." @default.
