According to the latest grid codes, wind turbines (WTs) are required to inject certain amount of reactive and active current into the faulty grid during voltage sags.However, studies have shown that the doubly fed induction generator (DFIG)-based WTs may lose stability under weak grid condition.So the impact of grid code requirement on DFIG system
An experimental study is conducted on the utilization of the inlet ethanol injection technique in order to evaluate its impact on the performance of a two-shaft T200D mini-gas turbine engine.The maximum degradation recorded in click here power output was 32.8% at the climate temperature of 45oC.Nevertheless, at that temperature, adding ethanol with
