摘　　要：SCS-500L功率振荡解列装置的判据基于功率振荡轨迹,原理简单,可控性好,工程应用方便。该装置采用高速数字信号处理技术,具有运算速度快、精度和可靠性高、人机界面友好等方面的优势,可适应电网结构和系统工况的灵活多变性。最后利用数字仿真验证了该判据和装置的有效性。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.
