چکیده مقاله:

In this study, we are trying to design an effective controller for a large variable speed pumped storage power plant connected to the grid will be provided in the generator mode. The controller is designed so that the both of simplicity and robustness in during of fault and post fault condition satisfied. Main controller of variable speed power plant are consisted of three separate controller, speed, power and dc link will be done by hydro turbine, Machine side and grid side converter respectively. Both of converter controllers are designed based on stator voltage oriented vector control and PI controller is usedfor hydro turbine on the steady state condition. Grid code compliance and fault ride through are important in pumped storage power plant than other renewable energy such as wind turbines because of power level in these plants are several tenfold of off-shore wind turbines. Thus, a nonlinear GCC (Grid codecompliance) is designed, added to PI controller, to two aims is tomeet. At first, increase the critical time during fault withoutdamage to the equipment, such as generators, switches andcapacitors. Secondly, improve transient and voltage stabilityduring and post fault condition. Finally, full state variableselectrical and hydro turbine will be used in matlab/simulink toverify design controller.
