| Abstract: | A design method and prerequisite to the rapid quasi-synchronization optimal control based on the quadratic performance index are described. By flowchart transformation, the hydraulic turbine regulating system with composite control over frequency and phase-angle is transformed into one with all-state feedback structure. The state equation for the system is given and the optimal controller designed. The relationships between the parameters of the optimal controller and the composite frequency-phase-angle controller are investigated by inverse transformation. Dynamic realtime simulation results obtained in a laboratory and operation results obtained in a water power plant are given. It is shown that the optimal controller has strong robustness and the turbine set reaches the synchronous point quickly after starting. There are six to nine chances per minute available for synchronization. |
