NOTICE ID: 20245201002 Upgrade of the Hydro-Generators Brakes Control System Questions and Responses
1. Do we know the distance between the Brake Control Enclosure and the Control Room? Is there an existing raceway/cable tray that can be utilized for new control cables?
Yes, there is a route and cable tray to run the communication cable, plus the max distance between the Generators Brakes and Control Room 250 FT.
2. Are there 3 spare digital inputs available on any of the SEL Axion 2244-2 digital inputs modules?
Yes, there is enough inputs digital and analogs in the PLC for the annunciator system.
3. Are there any spare slots on the SEL Axion Backplane?
Yes, there are few open slots.
4. What is the operating pressure of the brake system?
100 PSI.
5. How do they handle creep detection for the turbines?
The PLC from the governor send a digital signal (Alarm) to the Annunciator after 10 minutes if the
Generator doesn’t stop. This signal is already prewired all the way to the control room, but sometimes the PLC send the wrong signal and we believe the creep sensor needs to be recalibrated or replaced.
6. As we prepare our bid, we are seeking clarification regarding the license requirements. Specifically, we would like to know whether it is permissible for a subcontractor to hold the Texas Engineering Practice
Act and Rules Concerning the Practice of Engineering and Professional Engineering Licensure, or if it is mandatory for the prime contractor to possess this license.
A PE is required for this project. Please focus more on previous experience performing projects with
Hydo Generators.
