| Abstract | Common communication mode of electric energy data acquisition in power supply enterprise is PLC (power line carrier) or micro power wireless module with GPRS, but in the area with many mountains, disperse electric users, long distance to read meter, or rural power grid with GPRS or other mobile signal coverage limited, it is unable to realize automatic meter reading. WPLC takes advantage of small distortion of grid voltage and current waveforms to carry information, uses distribution network (10kV and 380V line) as communication medium, and realizes digital bidirectional communication. The WPLC cross zone data acquisition system is applied in a 35kV substation, and is tested after system is stable. Test data analysis indicates that the system performance meet the requirements; The average reading success rate of 10 consecutive days is 97.24%; integrated meter reading success rate is 97.92%; check the differences of daily frozen data, a real-time data and base data of power meter respectively, the correct rates are all 100%; select the zone with the furthest system installation which is 20km away to test, reading success rate is 100%. |
