Protection, Control and Monitoring System of Turbo Generator Industrial

Turbo Generator Control System

Turbo Generator could be used as an island power source parallel to electricity utility network, and to generate combined heat and power. In the latter case, gas exhaust of the Turbo Generator is recycled to be used to purify water.

It should be noted that Turbo Generator control system is designed for gas Turbo Generator operating based on a UGT25000 (DG80) engine.
