Nowadays, the proportion of wind turbines and the dimensions of wind plants have increased significantly all over the world. This paper describes a comparison of the power quality for wind power systems based on three different popular wind generators: the squirrel-cage induction generator (SCIG), the doubly-fed induction generator (DFIG) and the(More)
Doubly-Fed Induction Generator (DFIG) Wind Turbine (WT) is rather sensitive to power system faults and requires specific power converter protection, namely a crowbar. When the crowbar is triggered, the rotor is short circuited over the crowbar impedance, the rotor-side converter (RSC) is incapacitated and therefore the DFIG operates as a squirrel-cage(More)
This research presents a study on the small and large signal stability of IMPSA wind power plant with variable speed wind turbines connected to Vietnamese power system. Based on an aggregated wind park model in Power System Analysis Toolbox (PSAT) library, a dynamic model of Ninh Thuan - Binh Thuan grid, a province of Vietnam where a variable speed wind(More)
In wind power plants typically squirrel-cage induction generators (SCIG) tend to drain large amount of reactive power from the grid, potentially causing a drop voltage. To improve SCIG's power quality and transient stability, this paper investigates a new pitch angle control strategy, including normal scheme and Fault-Ride-Through (FRT) scheme, based on(More)

The temperature, radiation and other ambient environmental conditions are influencing the operation of solar cells. The shadowing phenomenon on solar cells causes the decrease of their output power. This paper analyses the effects of bypass diode configurations on photovoltaic systems operation under completely shadowed conditions. The authors analyze and(More)
Doubly-Fed Induction Generator (DFIG) Wind Turbine (WT) can be affected by power system faults and requires crowbar protection. When the crowbar is triggered, the rotor is short circuited over the crowbar impedance, the DFIG operates as a Squirrel-cage Induction Generator (SCIG) that tends to drain large amount of reactive power from the grid during fault,(More)
