| Abstract: | This paper presents the algorithm and control logic used in SCS-500L power oscillation islanding control device.Based on the line power oscillation trajectory measurements,this method has several distinct characteristics such as clear principle,good controllability and ease of engineering implementation.SCS-500L is a stability control device based on high speed digital signal processor(DSP) technology,having advantages of high-speed calculation,high-precision sampling,high reliability and a friendly man-machine interface and thus being capable of adapting to flexible requirements as a result of power system changes in topology and operation modes.Digital simulation results are given to validate the new method and the new device. |
