摘要
Abstract
Low frequency oscillation phenomenon of Longnan district in Gansu Province is described. Small signal stability of Longnan district is calculated by using power system analysis software package. Comparison among different results with or without power system stabilizer shows that ifthe power system stabilizer parameters are not set properly, the power system stabilizer will not restrain the low frequency oscillation, on the contrary, it will decrease the power system damping factor and increase the chance of oscillation. For generators located in the grid with constant structure change, it is recommended that generator test and the district united control test need to be performed to get optimal power system stabilizer parameter and to ensure power system operation safety and stability.关键词
