Embodiment Construction
[0063] The specific embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.
[0064] A power grid signal identification method of a star-connected high-voltage high-power power quality control device, comprising the following steps:
[0065] Step 1. Firstly, by sampling and calculating the three-phase input current signal of the device, confirm the phase sequence of the primary system where the device is connected to the power grid;
[0066] Step 2. Determine the phase sequence and phase relationship of the grid voltage three-phase PT sampling signal according to the phase sequence result of the three-phase input primary voltage, combined with the three-phase input current sampling signal of the device;
[0067] Step 3. After determining the primary phase sequence relationship of the grid voltage and the phase sequence and phase relationship of the three-phase PT sampling signal of the grid voltage, the sta...
