| Abstract: | The computing method of power quality parameters specified by the national standard is discussed in this paper, also the measurement and data analysis programs of frequency, harmonics and three-phase＇s unbalance are created by using LabVIEW, meanwhile, the network communication is implemented by adopting DataSocket technology. The LabVIEW based on-line monitoring and analyzing system of power quality has been designed, the system has improved the flexibility of on-line monitoring and the para- metric precision, furthermore, it is able to record the voltage events timely with steady operation in long time, which has certain utility Value. |
