Automatic Voltage Control: Automatic Voltage Control - Figure 8.20 gives the schematic diagram of an automatic voltage regulator of a generator. It basically consists of a main exciter which excites the alternator field to control…
Optimal Two Area Load Frequency Control: Modern control theory is applied in this section to design an Optimal Two Area Load Frequency Control for a two-area system. In accordance with modem control terminology ΔPc1 and…
Two Area Load Frequency Control: Two Area Load Frequency Control - An extended power system can be divided into a number of Two Area Load Frequency Control areas interconnected by means of tie lines. Without…
Load frequency Control and Economic Dispatch Control: Load frequency control with integral controller achieves zero steady state frequency error and a fast dynamic response, but it exercises no control over the relative loadings of various…
Proportional Plus Integral Control: Proportional Plus Integral Control - It is seen from the earlier discussion that with the speed governing system installed on each machine, the steady load frequency characteristic for a given speed…
Load Frequency Control of Isolated Power System: To obtain the dynamic response of Load Frequency Control of Isolated Power System giving the change in frequency as function of the time for a step change in…
Load Frequency Control of Single Area System: Let us consider the problem of controlling the power output of the generators of a closely knit electric area so as to maintain the scheduled frequency. All the…
Turbo Generator Excitation System: Power system operation considered so far was under conditions of steady load. However, both active and reactive power demands are never steady and they continually change with the rising or falling…
Optimal Scheduling of Hydrothermal Processes: The earlier sections have dealt with the problem of optimal scheduling of a power system with thermal plants only. Optimal operating policy in this case can be completely determined at…
Optimal Load Flow Solution: The problem of optimal real power dispatch has been treated in the earlier section using the approximate loss formula. This section presents the more general problem of real and reactive power…
