After drawing up a mathematical model of excitation control system of generator, the research group made out a rational smart computing algorithm to complete the designing. And, on this basis, the group successfully developed the digital excitation controller which is lower than the imports in production cost, but excellent in performance.

The controller plays a role of stabilizing wattles power. And users can alter index values at their will in accord with the characters of generators.

It has also functions of diagnosing and settling troubles through real-time monitoring.

It has been introduced into various hydro-power stations, proving highly effective.

The respected Supreme Leader Kim Jong Un in his New Year Address for this year called for conducting the dynamic campaign to lower the loss of electric power and increase electric-power production as much as possible by maintaining and reinforcing imperfect generating facilities.
