MACH7 - Highlights

Philosophy und Logic

• 100% digital control and regulation.

• The only system that follows 100% of the GE gas turbine control, regulation, and safety. Then there is no re-learning process for your personnel.

• Variable fast start for the lowest thermal stress in the minute reserve. MACH7 is the only controller with automatic fast starts calculated as a function of time remaining in a time window (for the minute power reserved market). This reduces the thermal stress on turbine hot gas path parts as much as possible.

• Automated grid re-energization over a large distance. The black start ability and the grid re-energization was demonstrated many times in extensive tests to the full satisfaction of all the parties involved.

• Fully automatic auxiliary power supply for a large power plant a long distance away.

• Complete programming and calibration from a remote location.

• Time stamping to a the thousandth of a second for all alarms, events, and measured values.

• No additional training courses required for personnel experienced with Siemens equipment.

• Forcing and presetting all inputs, outputs, and variable signals Hardware and Maintenance.

Hardware and Maintenance

• Standard industrial components.

• Millions in worldwide use.

• Not an original equipment manufacturer solution.

• All parts used conform to German and European standards.

• Clear layout of components.

• Easy access to all terminals.

• No additional space requirements compared to the old control panel.

• The MACH7 control panel is a completely independent system and requires no additional components or applications. Regardless of what happens to the DCS or other plant communication networks outside of the gas turbine controls (server failure, break in the bus connection, …), the control panel remains fully available and operable (of course all the diagnosis functions remain available).
