HYDRO SERVICE & RETROFIT SOLUTIONS T.MOD Governing System Reset & Upgrade Hydro PlantLife® Programme Increase the capability and performance of your governing system with the Alstom Turbine MOdular & Digital speed governor (T.MOD). TEPID™: for improved startup and transient response Alstom T.MOD is based on PLC and TEPID™ algorithm in order to yield superior speed transient response both upon unit startup and in response to system load transients during grid, isolated or islanded operations. TEPID™ is a Transient-Enhanced PID with setpoint feedforward based upon a “double-derivative” strategy with conventional PID parameters expression. Benefits Easy tuning of the doublederivative strategy with conventional PID parameters expression IMMEDIATE RESULTS Upgrading Controls Reduces Unit Downtime Short outage approach Optimise commissioning time with shadow studies, manufacturing and settings calculation •Flexibility of PLC solutions: easily customisable, PLC user-specified, standard & advanced functions, integration of user needs Can replace any existing governor system (Alstom & Other OEM1) Easy & quick installation with short outage approach Local/remote control with wide range of communication protocols Customisable scope of replacement with easy hydraulic & electric interface connections Meets or exceeds IEC & IEEE Governor standards Off-the-shelf spare parts Can be integrated into Distributed Control System (DCS) • • • • • • • RPWR/PRSHT/HYDT.MOD/EN/12.2013/FRA/2118 1 OEM: Original Equipment Manufacturer Bulb, Kaplan, Francis, Pelton and pump turbines © ALSTOM 2013.

REDUCING COST OF ELECTRICITY A cost-effective system TEPID™ provides a superior governing response in unit startup, stability test, on-line response and load rejection. Feedback form the Field: The Upper American River Project upgraded a hard-wired relay-based governing system to T.MOD with TEPID™ (including hydraulic pilot control valves, magnetic level indicator, pressure transmitter, solenoid-driven unloader valves and new speed detection/speed switch). Improved generating efficiency, standardisation of spare parts and troubleshooting, reduced maintenance and leverage system resources and training were just some of the immediate benefits. Less maintenance, easier troubleshooting and spare parts standardisation during the 20-year lifetime of the system. INCREASING FLEXIBILITY & RELIABILITY 100% From the start, TEPID™ performs immediately at 100%, with zero speed overshoot in a faster response time.
