Embodiment 1
[0085] A kind of synchronized phasor measurement method based on Clarke transform that the preferred embodiment of the present invention provides, comprises the following steps:
[0086] Step 1: Extract the three-phase voltage / current signal, perform sampling and discrete Fourier transform, and obtain the pre-estimated value of the phasor measurement of the fundamental wave of the three-phase signal;
[0087] Step 1.1: Use voltage transformers or current transformers to extract the three-phase voltage / current signals in the grid x abc (t);
[0088] Step 1.2: With a fixed sampling frequency f s For three-phase voltage / current signal x abc (t) Sampling to obtain the discretization sequence x of the three-phase signal abc (n), where n=tf s , n represents the number of sampling points, f s Indicates the sampling frequency;
[0089] Step 1.3: With the same filter frequency ω 0 =2πf 0 / f s , respectively for the discretization sequence x of the three-phase signal abc (n) D...
