Summary of Scope of Work: Digital governor upgrades are required on all six main hydropower units of Little Goose Hydroelectric Power Plant, located in Starbuck, WA. Individual main unit capacity is 135 megawatts (MW) for a total powerhouse capacity of 810 MW. All six main units are Kaplan type with adjustable turbine blades. There are two families of hydropower units at Little Goose powerhouse, both utilizing adjustable turbine blades. Units 1 through 3 utilize mechanical actuator type governors manufactured by Pelton and were completed in 1970. Units 4 through 6 utilize electrical analog actuator type governors manufactured by Woodward and were completed in 1978. All six units have original governors with proportional, integral, and derivative (PID) control for both the gate and blade servomotors. The governors control unit speed by operating wicket gates through a combination of hydraulic, mechanical and electrical means. The governors control blade pitch by adjusting blade angle through a combination of hydraulic, mechanical, and electrical means. Unit 1 through 3 governor speed reference is generated by a permanent magnet generator (PMG) whereas unit 4 through 6 governor speed reference is generated by a speed signal generator (SSG). Digital governor equipment has already been procured and shall be provided under this contract as Government Furnished Equipment (GFE) for contractor installation. Installation plans and specifications contain prescriptive and performance requirements for the installation and testing of GFE digital governor equipment and include detailed wiring for Unit 2 and Unit 5. The contractor will perform the detailed wiring for Unit 1 and Unit 3 similar to Unit 2 and detailed wiring for Unit 4 and Unit 6 similar to Unit 5. The Contractor will perform the removal of the existing governor components and the installation of the new GFE digital governors. General Work As part of the digital governor installation work, a front panel of the actuator cabinet will be removed and replaced with a new governor cabinet with a GFE Human Machine Interface (HMI). An additional GFE HMI will be installed in the control room and will be capable of controlling all six units. As part of the digital governor upgrade, the new digital governor controller will replace the hardwired relay logic for automatic unit start/stop sequencing. The start sequence will bring the unit to speed-no-load, and the stop sequence will shutdown the unit after the breaker has been opened. The governor will include automatic, semiautomatic, and manual starting. Upon completion of all demolition work within the governor actuator cabinets, the interior surfaces will be stripped and repainted. Mechanical Work, each unit The existing distributing valves, servomotors, and pump drive motors will remain. All gate and blade distributing valves will be cleaned, inspected and rebuilt using existing components or new internal parts as needed. New gaskets, seals and O-rings will be installed and the valves will be reassembled to OEM specifications. Existing servomotors and pump drive motors of the governor systems require no rework or refurbishment. The work includes installation of a new GFE Electro-Hydraulic Interface (EHI) module which includes a manifold block, gate and blade proportional valves, duplex oil filters with clogged oil filter switch contacts, and emergency shutdown valve, a Linear Variable Differential Transducer (LVDT) on the servomotor and blade distributing valves for position feedback to the proportional valves, new hydraulic tubing, isolation maintenance valves (padlock capable), and redundant Magnetostrictive Linear Displacement Transducers (MLDTs) for blade and wicket gate position. No rework or refurbishment of existing gate lock solenoid valves will be required. The Contractor will be required to provide detailed shop drawings for the interconnections of all new and existing GFE and Contractor provided parts and accessories. The governor control column and all mechanical linkages associated with it, including the mechanical pilot valves for the gate and blade will be removed. All speed adjustment, gate limit and gate position equipment will be removed. The existing Lead, Lag, Alarm and Shut Down governor oil pressure switches shall be relocated in the cabinet as necessary to facilitate the installation of the new digital governor cabinet. The existing duplex strainers for the gate and blade pilot valves will be removed. GFE LVDTs will be installed to monitor each unit's gate and blade distributing spool valves' position to provide intermediate feedback (relay restoring). The existing feedback system, consisting of cables, pulleys, weights, and etc., will be removed along with the associated mounting hardware, piping, and conduit. All unused cable ports in the governor actuator cabinet will be closed with a threaded metal cap with o-ring. GFE redundant MLDTs will be installed and affixed to an aluminum channel mounted on the servo motor #1 using a combination of a U-bolt mount and cantilever bracket. The MLDT assembly will have a hinged aluminum cover with winged self captured fasteners that is to prevent exposed pinch points in coordination with OSHA requirements. The existing feedback system consisting of cables, pulleys, sheaves, and weights, along with the associated mounting hardware and piping, will be removed from the governor cabinet up to the point of connection with the new blade angle feedback assembly. The new blade angle feedback assembly will be supported by a combination of a U-bolt support on the existing blade angle oil line and a support backed mounted to the bridge. The MLDT conduit will be routed from the assembly up to the existing SSG/PMG junction box, and then will be routed to the governor cabinet. Permanent magnetic generators shall have existing rotor and stator windings removed. Speed signal generators shall have existing pickup sensors removed. Each PMG and SSG will retain one existing mechanical overspeed switch and each will receive two new proximity probes providing speed reference and creep detection. Electrical Work, each unit For all units, the following components (along with wiring) located on the front of the governor control cubicle will be either removed or relocated: 3D CAM E-Stop Switch, 3D CAM HMI, Analog Governor, Blade Position Indicator, Dashpot By-Pass Control, Gate Limit Control Knob, Gate Limit - Gate Position Indicator, Generator Air Brake Control Switch & Indicating Light, Generator Air Brake Pressure Gauge (Duplex), Nitrogen Shutdown Indicating Lamp, Speed Droop Control, Speed Droop Indicator, Speed Indicator/Tachometer Speed Level Control/Speed Adjustment Control Knob, Speed Level Indicator/Speed Adjustment Indicator, System Pressure/Governor Oil Pressure Gauge, Transfer Valve Control/Gov. Transfer Control Switch & Indicating Lights, Transfer Valve Position Indicator. The existing interface to the Generic Data Acquisition and Control System (GDACS) and Station Control Console (SCC) will be retained. Redundant Zero Velocity Pickup (ZVPU) proximity probes installed at the PMG and SSG gear teeth shall serve as creep detection and speed signal. The primary speed signal will be from a new frequency transducer connected to the Unit's potential transformer (PT). GFE digital governor cabinet with PLC, power supplies, interposing relays (controlled by the PLC output modules), and associated equipment will be installed, along with all necessary components, wiring, and conduit. A fiber optic cable will be routed in rigid metal conduit from each generator unit to a new network switch located in the control room. Any fiber optic junction boxes or patch panels will have a lockable cover. A GFE free standing touch screen governor HMI will be installed in the control room at the operator's desk. Copper Ethernet will be routed from the new network switch to the operator desk HMI. As part of the control circuit changes, the several devices/relays and associated wiring located within panels of the unit switchboard and actuator cabinet will be removed and their functions will be incorporated into the new digital governor. GFE digital governor system shall interface with GDACS via hardwired connections paralleled off the existing devices or terminal blocks at each unit's switchboard. These hardwired connections may or may not be used by GDACS immediately after installation. General Contract Requirements The contract requires completion of all work within a finite on-site installation work window of approximately 235 calendar days.
