Description
Summary:The thesis deals with a procedure for developing mathematical models of hydraulic components for hydroelectric power generating units. Hydraulic system components modelled are the penstock, reservoir, surge tank, Francis turbine and the wicket gate actuator. A modelling philosophy is suggested. The thesis proposes that for a generator experiencing a sharp transient, such as line breaker reclosing, its capacity to maintain synchronism can be enhanced by taking advantage of waterhammer to sharply reduce the turbine's hydraulic torque input to the generator during the first few swings of the tie-line. Results of computer simulations included support this claim. === Applied Science, Faculty of === Electrical and Computer Engineering, Department of === Graduate
