 Effects of DFIG wind power generation on Vietnam power system operation
Tác giả hoặc Nhóm tác giả: Nguyen Huu Hieu ; Le Hong Lam ; Cao Thanh Luu ; Tran Quoc Tuan
Nơi đăng: PowerTech, June 29 2015-July 2 2015, IEEE Eindhoven; Số: 15418916;Từ->đến trang: 1-4;Năm: 2015
Lĩnh vực: Kỹ thuật; Loại: Báo cáo; Thể loại: Quốc tế
TÓM TẮT
Nowadays, renewable energy sources are more reliable and developed than before in which wind power is a considerable factor. Therefore, A thorough comprehensive knowledge about modeling, control and responses of wind generators to practical disturbances is very necessary and vital. The double fed induction generator (DFIG) is popular and effective for a wind turbine with the noticeable characteristics of variable pitch control and rotor-side converter including. Typically, the paper tries to describe and explain the DFIG wind turbine control model built in PSS/E before the model is applied to a bulk power system - the reduced equivalent power system in Soc Trang, Vietnam. It wants to observe, analyze and evaluate dynamic responses to disturbances such as loss of a generator. During the simulation, due to using an uninterrupted operation and fast control of DFIG converter, the DFIG wind turbines response successfully to each disturbance. It wants to understand that under transient fault conditions, both the voltage and the system frequency are important to the assessment of influences of wind power on the overall power system.
