WEStation Software Maintenance and WEStation Hardware Maintenance

I had the privilege of attending the WEStation Software Maintenance and WEStation Hardware Maintenance courses that were offered by Westinghouse for the WDPF II control system. This system was the primary control for the two 501D5 gas turbines (units 4 & 5) at Brazos Electric’s R.W. Miller plant. I worked on this system for six years at the Miller plant and was quite impressed with the UNIX based operations and Engineering stations. I am sorry that the controls industry has moved away from the UNIX based systems as the new Windows based systems are not as secure due to the mass use of the operating system. The more popular an operating system, the more viruses and people who are able to find security holes there will be. The industry moved to Windows primarily because development is less expensive, and plants don’t have to retrain personnel on the system if they are already Windows savvy.
