ABSTRACT:
A method of monitoring a high voltage electrical power system is described in which a system acquires measurements the small perturbations in power system parameters, from which are derived the system dynamic characteristics used to determine power transfer limits that take account of power system prevailing conditions. Further, a method is described that can be used to identify the probable source of power system oscillations that can limit secure power transfer.
