摘要：

With new systems capable of making synchronised phasor measurements there are possibilities for real-time assessment of the stability of a transient swing in power systems. In the future, online control will be necessary as operating points are pushed closer toward the margin and fast reaction time becomes critical to the survival of the system. A piecewise constant-current load equivalent (PCCLE) technique is developed which utilises synchronised phasor measurements to provide fast-transient stability swing prediction for use with high-speed control. A numerical simulation is conducted on IEEE 39-bus system equipped with ten phasor measurement units to test the effectiveness of the PCCLE technique.
