چکیده
|
Various methods are used to produce electrical energy, each of which has its own advantages and disadvantages. the power plant is one of the important parts of the power system, which is responsible for the proper production of electrical energy. in this study, the dynamic behavior of load frequency control is compared and analyzed for three power systems, each including a steam power plant, a hydro power plant, and a gas power plant. the state equations of each system are separately expressed, and then using the analysis of eigenvalues (system modes), the dynamic behavior of the power system is shown for changes in the consumption load. the power system model is simulated in matlab software showing the correctness of the analysis of eigenvalues. in addition, the power system model in simulink matlab for each power plant is separately designed and the correctness of the results is shown. the frequency response of the transfer function, i.e., frequency changes to load demand changes, is shown in each production unit. the results of simulation and examination of the power system modes reveal that the steady state response of the three production units is similar to step changes in load demand, and only the speed of reaching the steady state will be different in them.
