该控制器以PM U得到的区域间电压相角差信号作为输入信号,能够直接有效地反映区域间低频振荡特性。
This controller's input signal is the voltage phase Angle difference between two areas obtained by PMU, which can effectively reflect the inter-area low frequency oscillation characteristics.
输入信号的频率只有位于噪声能量集中的低频区域,才有可能使输入信号被适量的噪声选择而产生随机共振现象。
Only the frequency of the input signal locates in the low frequency region, can the signal be selected by a proper noise level to produce SR phenomenon.
传统的PSS使用本地可测量的发电机电磁功率、转速等作为输入信号以抑制低频振荡。
The traditional PSS use the local signal such as the generator electromagnetism power or shaft speed as its input to restrain low frequency oscillation.
