Woodward 9907-175 2301D-ST Digital Load Sharing
Product Overview
- The Woodward 9907-175 is a 2301D-ST Digital Load Sharing and Speed Control, designed for precise speed and load control of small steam turbines driving generators, pumps, or compressors in industrial applications such as power generation, oil and gas, and process industries. This microprocessor-based control unit is part of Woodward__ 2301D series, offering advanced digital control for single-valve steam turbines with isochronous or droop speed governing, load sharing, and protection functions. The 2301D-ST is tailored for steam turbine applications, providing automated startup, shutdown, and precise speed regulation. The 9907-175 is a specific variant of the 2301D-ST, featuring a high-voltage power supply (88_132 VAC or 90_150 VDC) and potentially specific firmware or configurations compared to other 2301D models (e.g., 9907-173). It integrates with Woodward actuators and supports communication with plant control systems. The 9907-175 features a rugged design for reliable operation in harsh environments. It is distinct from Woodward__ genset controls like the EasyGen series (e.g., 8440-2179 EasyGen-3500XT, 9907-1182), DSLC series (e.g., 9905-976, 8923-1262), 505 series (e.g., 9907-163, 9905-792), 2301A series (e.g., 9905-463), EGCP-3 series (e.g., 8444-1082), SPM-D2 series (e.g., 8446-1048), SPM-A series (e.g., 9907-028), MicroNet Plus (e.g., 8800-1001), TG-13 (e.g., 8516-050), Peak150 series (e.g., 8200-176), ProAct series (e.g., 8237-2595), 723PLUS series (e.g., 8270-1013), EPG systems (e.g., 8290-195), electronic governors (e.g., 8406-121), and actuators (e.g., 8408-921), focusing on digital control for small steam turbines.
