Entec - Model DTC-Vario - Digital Control System

The modularized software allows simple parametrisation of the application. The software remains standard leading to a maximum of security and compatibility.

The DTC-Vario is a full system integration by centralizing control, protection and metering in one device. Less components results in increased availability at low costs.

• Centralized, fully automatic process control (Start, Run and Stop mode of small hydropower stations)
• Multiple turbine management, depending on consumption and waterlevel
• Fully automatic restart after harmless errors like water shortage or mains power failure
• Monitoring of speed, frequency, power, water level. voltage, reactive power, cos phi, etc. (over 40 redundant security functions)
• 4 alarm classes
• 3 independent algorithms for stop, fast stop and emergency shutdown
• Island operation, grid connected operation as well as resynchronisation between grid and local island-grid
• Operation with synchronous or asynchronous generators
• 2 governors per turbine/ oil-hydraulically or electrically driven
• Water level control, frequency control, power control with or without interval operation mode
• Local operation by panel or by PC
• Remote operation possible by PC and modem or fieldbus connection
• Detailed data acquisition of production data and alarm history
• SMS alarms and status
