Development of a new power quality monitoring terminal based on configuration

With the increase of the non-liner power loads and impact loads in power systems, the pollution of power quality is becoming more serious. It is important to put up multi-dimensional monitoring and construct monitoring network. In this paper the hardware and software scheme of a new power quality monitoring terminal based on configuration software is introduced in detail, which is applied to different kinds of fields and can carry out samples and data analysis of various parameters of power quality quickly and precisely. It has powerful functions, easy and flexible to be controlled, operated stably, small size and decrease the investment obviously.
