The U.S. Army Corps of Engineers � Tulsa has been tasked to solicit to supply two new static type exciters, associated components, and wiring for the two main hydrogenator units at Broken Bow Powerhouse for the U.S. Army Corps of Engineers (USACE) within the Southwestern Division (SWD). The Contractor will furnish two exciters (not to include power potential transformers) in accordance with Plans and Specifications and the Government will install the Contractor furnished systems. Once installed, the Contractor will commission the Contractor-furnished, Government-installed systems and provide model validation testing. Broken Bow Dam is in southeastern Oklahoma on the Mountain Fork River in McCurtain County. There are two hydroelectric units at Broken Bow. The generators were manufactured and installed by Allis-Chalmers in 1970. They are rated at 52,632 kVA, 2205A, 0.95 PF, 13,800V, and 128.6 RPM, with a 115% continuous overload capacity (60,527 kVA). The stator windings in both units were rewound to the same rating (52,632 kVA with 115% overload capacity) in 1984 by Thomson Electric LTD. The two main units at Broken Bow have existing excitation systems for these main units that have reached the end of their design life, causing issues including failure to meet NERC requirements and lack of support and spare parts. Due to the age of these exciters (approaching 30 years) and the challenges listed above, Tulsa District will proceed with replacing the exciter systems using Contractor Furnished equipment. The Government (Powerhouse staff) will install the new exciter systems. Once installed, the Contractor will Commission the new exciter systems and perform model validation testing. The new exciters will be Government installed in the same location as the existing and connected in a close-coupled configuration with the existing PPTs, which will be retained. The size of new exciter cubicles will be required to be made to closely match the space occupied by the existing exciters. The Contractor will supply new excitation cubicles, including new redundant controllers, redundant rectifier bridges with redundant fans, redundant power supplies, rectifier supply breaker, and other associated excitation system control equipment. Further, the Contractor will supply the bulk cable required for installation of new exciters, to include control cable and cable from the exciter to the collector rings. The Contractor will perform commissioning and model validation testing. The Contractor will also provide Structural Seismic anchoring analysis and design and supply seismic anchors for the new exciter cabinet foundations. The existing exciters were manufactured by Siemens and installed in 1995. The maximum continuous current rating is 929 Adc, the positive ceiling voltage is 375 Vdc, and the ceiling current rating is 1450 Adc for 30 seconds. The existing power potential transformers (PPTs) for both units were furnished by PEMCO and are rated for 460 kVA, with a ratio of 13,800/320. The existing generator, exciter, and PPT nameplates are shown below. The purpose of this synopsis is to gain knowledge of interest, capabilities, and qualifications of various members of industry, to include the small business community: Small Business, Section 8(a), Historically Underutilized Business Zones (HUB-Zone), Service-Disabled Veteran-Owned Small Business (SDVOSB) and Women-Owned Small Business (WOSB).
