Title: Frequency detection method
Inventor: KAMEOKA TAKAHIRO
IPC: G01R23/10
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To obtain a frequency detection method in which computing and processing speed is increased and which enhances quick availability by computing times between zero-crossing operations at every phase difference in respective three phases, adding the times to find the cycle. SOLUTION: Times T1 , T2 , T3 in every phase difference of 120 deg. at respective phases are computed from a three-phase AC waveform, a cycle T is found, and a frequency is found on the basis of the cycle T. That is to say, within one cycle T of one phase, e.g. a U-shape, in a three-phase waveform, the time T1 at an electrical angle of 120 deg. up to a zero-crossing position B at a next V-phase from a zero-crossing position A at a U-phase is computed. Then, the time T2 up to a zero-crossing position C at a next W-phase from the zero- crossing position B at the V-phase is computed, and the time T3 up to a zero- crossing position D at a U-phase from the zero-crossing position C at the W- phase is computed. The times T1 , T2 , T3 are added, and the cycle T is found, and a frequency (f) is found by calculating f=1/T (Hz).  In this manner, since a computing and processing operation is performed at a cycle of 120 deg., a frequency detection method can be processed at a cycle of 2/3 as compared with a cycle of 180 deg. in conventional cases.
