This paper presents the simulation results of using a static synchronous compensator (STATCOM) to improve damping of a grid connected wind power system (WPS). The operating performance of the studied WPS is simulated by an equivalent doubly fed induction generator (DFIG) driven by an equivalent wind turbine (WT).

In this paper, the application of a series grid-side converter (SEGSC) connected to a wind-turbine-driven doubly fed induction generator (DFIG) is introduced. The setup allows the wind turbine system an uninterruptible fault ride-through of voltage dips. The SEGSC can compensate the faulty line voltage, while the DFIG wind turbine can continue its nominal operation as demanded in actual grid codes.

The experiment results reveal suitability of using a mono block centrifugal pump in hydro turbine mode. The results confirm that the pump in hydro turbine mode operate at higher heads and discharge as compared to the pump mode operation. BEP (best efficiency point) for the pump in hydro turbine mode is lower than in pump mode operation. Correlations proposed by earlier researchers for performance prediction of pump in hydro turbine mode are also tested.

The results of simulated transients for three typical PWR accidents are presented: a turbine trip with station blackout, a large break loss of coolant accident and a small break loss of coolant accident. The analyses show that the safety criteria are respected and that the reactor quickly reaches a safe shutdown state without operator action and external power.

This paper presents the modeling and simulation of wind turbine driven by doubly-fed induction generator which feeds ac power to the distribution network. A stator flux oriented vector control is used for the variable speed doubly-fed induction generator operation. By controlling the generator excitation current the amplitude of the stator EMF is adjusted equal to the amplitude of the grid voltage.

This paper introduces the development of a transient monitoring system to detect the early stage of a transient, to identify the type of the transient scenario, and to inform an operator with the remaining time to turbine trip when there is no operator's relevant control. This study focused on the transients originating from a secondary system in nuclear power plants (NPPs), because the secondary system was recognized to be a more dominant factor to make unplanned turbine-generator trips which can ultimately result in reactor trips.
