摘要： The present invention relates to a measuring method and a system of phase angle of electrical system sinusoidal quantities, the method includes selecting a key station as a reference station, other stations desired to be measured as sub-stations in electrical system, establishing an unitized standard unit of time, and so, avoids delay in signal transference. Further, signals which are designated with standard unit of time are compared to each other, in order to find the phase angle of the signals. Otherwise, the signal of the reference station may also be transferred to the sub-stations as a reference signal. The signals which are transferred to the sub-stations are corrected and compensated for phase delay in transference, further they and the measured signals of the sub-stations are calculated in order to find the phase angle. Since the present method is used to measure the phase angles of electrical system sinusoidal quantities, the electrical system can be measured in real time, therefore the method provides a new way to measure phase angle easily.
