Wind Turbine Generators (WTG) converters introduce harmonics into the grid, and the guidelines to measure properly this power quality phenomenon are addressed in the standard IEC 61400-21. This paper presents the design, implementation and validation of a harmonic measurement system prototype for wind parks. The prototype was developed in a hardware platform that comprises a real-time controller,...
The major source of inaccuracy in dynamic power simulations arises from the models used to represent loads, due to their stochastic nature. Nevertheless, measurements of the electrical system dynamic response are available from a large number of sources like power quality monitors and other disturbance monitoring devices. That means that real world recorded data may be used to fit a mathematical description...
This paper discusses methods and criteria for the assessment of the low voltage ride-through (LVRT) needs of the power grid. Simulation techniques are used to investigate both how voltage dips caused by short-circuits spread over the grid and what impact do they cause in the operation performance of power systems with wind generation. The analysis is performed for wind turbines (WT) with different...
