Protective Relay & Annunciation Replacement

The principal components of work include: A. Modify existing electrical protection system for the two pump generator units at Mount Elbert Powerplant. Includes: 1. Replace existing relays with new digital multi-function relays. 2. Providing new time synchronization system. 3. Replacing DC distribution circuit breakers in modified control boards. 4. Performing modifications to the existing control boards. B. Modifying existing facility annunciation system: 1. Replace existing facility annunciation system with new digital annunciation system. 2. Develop programming and graphic displays to implement new annunciation system. 3. Remove and replace functionality of existing relays associated with the annunciation system 4. Provide new cabinets and enclosures for the annunciation system. C. Work includes at a minimum: 1. Field investigation of systems and drawings. 2. System design and analysis. 3. Demolition. 4. Installation. 5. Furnish equipment and components. 6. Control panel replacement and modifications. 7. System programing. 8. Testing and commissioning. 9. Training. Projects similar in scope and complexity are defined as work involving the following: 1.) Design and installation of complex hydroelectric pump/generator protection and annunciation systems. 2.) Provide coordination between multi-faceted electrical control and monitoring systems. 3.) Upgrade outdated electromechanical equipment to PLC and microprocessor driven alternatives, maintaining the same panel footprint. 4.) Integrating new equipment with existing plant control and maintenance monitoring network. 5.) Demonstration of pre-design, pre-planning, and execution of essential equipment construction prior to mobilization. 6.) Demonstration of maintaining a tight schedule, during seasonal weather conditions, with multiple outages and coordination between multiple parties to minimize plant downtime. 7.) Perform commissioning of new systems to ensure full operation that meets or exceeds previous protections and annunciation equipment.
