Tóm tắt:TÀI LIỆU THAM KHẢO:This study examines the transient stability of the power system in Tra Vinh province, where eight wind power plant projects operate with a total capacity of 464 MW. Ensuring system stability during normal operations and after major disturbances-such as short circuits, substation failures, or load imbalances-poses significant challenges. Transient stability is particularly critical for wind generators due to their fluctuating output characteristics, which depend on environmental factors like wind speed. Unlike conventional steam or hydro generators, wind turbines are typically connected to the grid via inverters, resulting in different responses to disturbances. Most wind power plants in Tra Vinh use induction generators, which are prone to losing synchronization during instability, potentially leading to system-wide failures. This study analyzes and simulates the transient stability of a power system integrating induction generators using PSCAD/EMTDC software, providing insights into stability challenges and potential mitigation strategies.
