(p394) What is the standard steady-state droop? (p394) What is the function of a transient droop? (see Figure 9.8, p396) 9.1.4 Detailed Hydraulic System Model 9.1.5 Guidelines for Modeling Hydraulic Turbines(pp417-418) Governor tuning studies Transient stability studies(Figure 9.10) Small-signal stability studies(Figure 9.7 + Figure 9.10) Long-term dynamic studies 9.2 Steam Turbines and Governing Systems 9.2.1 Modeling of steam turbines See Figure 9.23 (p430) 9.2.2 Steam turbine Controls Governing systems: three basic functions: (pp432-434) normal speed/load control governor system and AGC over-speed control operating control valves over-speed trip tripping boiler Turbine controls Start-up/shutdown controls Auxiliary pressure control Generic model of steam turbine controls(pp444) Figure 9.36(p445) 9.2.3 Steam Turbine Off-Frequency Capability Blade vibration and resonance (p444) Over-frequency and under-frequency operations (pp447-448) 9.3 Thermal Energy Systems 9.3.3 Modeling of Thermal Energy Systems It is important in the long term dynamic response of power systems. (p459) Process physics Auxiliaries Protections Controls Chapter 11 Control of Active Power and Reactive Power 11.1 Active power and frequency Control Problem: Why it is important to keep the constancy of frequency and its integral? What are the basic idea of load/frequency control? 11.1.1Fundamentals of Speed Governing Generator response to load change Load response to frequency deviation Example 11.1 Isochronous governor Governors with speed-droop characteristic Percent speed regulation or droop Load sharing by parallel un
