| Abstract: | In order to solve the hidden troubles of high-frequency in isolated power grid caused by the tripping of the link line when outputting high power and to improve the stability of grid frequency,the high-frequency problems of isolated grid are described firstly as well as its harm,and then aiming at the problems,four measures are proposed,that is,generator triping,fast adjusting port,runback(RB) and fast cut back(FCB).The effects of each measure and their influences on power grid and power plant are compared ... |
