Aiming at the current situation that the large quantity,the dispersive position and the insufficient reactive-power compensation of distribution transformers,a intelligent monitoring equipment based on GPRS(General Packet Radio Service) and low-voltage dynamic reactive power compensation technology,is researched.

Application of Dynamic VAr Compensation Protection System for Medium-Voltage Transformer Substation;

Design of embedded control system for dynamic low-voltage reactive compensation;

Aiming at the controlling means and running impacts of the former low-voltage reactive compensation sys-tems ,the paper sets forth an application system of higher accuracy reactive compensation control based on serial inter-face,and introduces the principle of measure and control,hardware and software in the system.

The low voltage reactive compensation collector-distributor control system in ferromanganese-silicon furnace is developed.
