Controlling and protecting steam turbines

Mitsubishi Electric has launched the Turbiset Steam Turbine Control and Protection solution that it says can be used with any manufacturer’s turbine.

Steam turbines play a key role in energy plants and must be optimally controlled to extract the maximum energy from the steam. Probably as important as ultimate efficiency, is the fact that steam turbines are mission critical equipment; hence they must be rigorously protected to ensure that they remain reliable, safe and operate continually.

Turbiset Steam Turbine Control and Protection solution is claimed to combine optimal control strategies, and up to triple-redundancy protection PLCs as standard to ensure turbines operate efficiently and reliably to generate maximum revenue. The architecture of the PLC network is designed so that the turbine remains completely protected, even if one of the three protection PLCs requires replacement.

Turbiset is available for new turbines, but also provides an upgrade path for existing turbine control systems. Before a Turbiset package is installed, it simulates the turbine and associated systems to 100% pre-validate the control system, ensuring reliable, optimum control and critical protection of the steam turbine when it is recommissioned and brought online.
