Through the analysis,it shows that the installation of reactive compensation devices on 10 kV distribution lines can reduce losses.

With the continuous expansion of the scale of power grids, it need more and more reactive compensation devices.

Study on a Feedback Reactive Power Compensator and Its Application;

The application of reactive compensation device in power supply lines in the on-pole transformer is a new subject.

With the development of electronic technology and computer control technology,various kinds of automatic and quick reactive compensation devices have come into being in succession,which greatly advances the development of SVC compensation technology.

In the light of the problems existing in medium-sized water pump of mine,this paper advances the suggestion on adopting the reactive power compensator and AC soft starter in medium-sized water pump,and introduces the principles,application and benefit of the reactive power compensator and AC soft starter.

Via analysis of GB/T 15576 standard for low-voltage whole set reactive power compensator,the differences of experimental project,method and requirement between new and obsolete edition were described systematacially.

This paper introduces the applications of fuzzy mathematics in power plant siting,power network planning,configuration of reactive power compensation device,as the examples of the applications of fuzzy mathematics in power system planning.
