Power system stabilizer system having improved integrity checking scheme |
摘要 |
In a system for stabilizing the operation of an electrical generator connected to a power distribution network, which system includes a power system stabilizer operating through a modulator circuit to control generator oscillations, there is included a scheme for testing the integrity of the power system stabilizer and modulator circuit which involves the application of a test signal having known values to the power system stabilizer. This test signal propagates through the circuitry and the resultant output is demodulated to be compared with a stored representation of the test signal to thus yield outputs representing the gain and phase shift of the power system stabilizer and modulator circuit in combination.
