Diesel Power Generation

This 60-day telephone notification is provided in accordance with 10 CFR 50.73(a)(1) to report an invalid actuation of the Emergency Diesel Generators (EDGs) reportable under 10 CFR 50.73(a)(2)(iv)(A). Due to the shared configuration of the onsite AC Electrical Distribution System, this event is applicable to both Units 1 and 2.

At approximately 2114 hours Eastern Daylight Time (EDT), while Operations personnel were making preparations for Unit 2 main turbine generator synchronization to the grid, a Main Generator Reverse Power Trip occurred. Main Generator Reverse Power Trip was actuated after adjusting the Manual Voltage Regulator on the Main Generator. The reverse power relay operates the Generator Primary Lockout which initiates a turbine trip and start of all four EDGs. These features functioned as designed. The main generator breaker was open at the time of the event; as such, electrical power was not lost to the emergency busses.

All four EDGs started and operated as expected. Because electrical power was never lost to the emergency busses and none of the EDGs loaded to their respective emergency busses, the actuations were considered to be partial.

The EDGs were returned to their standby line-up by 2229 hours on May 7, 2013. Since no actual bus under voltage condition existed which required the EDGs to start and the start was not in response to actual plant conditions satisfying the requirements for initiation, this event has been classified as an invalid actuation.

Ever since electricity has become a part of our daily life, we have been using more and more of it each passing year. We are unable to keep our hands off the gizmos and gadgets that have arisen out of science and technology. But then, in this entire craze, we at times lose track of the real world around us.

We have come to a state where we cannot really imagine living without electricity. Builders and developers being well aware of this fact have resorted to using diesel generators to give a 100% power backup. As a result of this, we end up polluting the very air we breathe and screening the diamond dotted skies too!

This episode takes you behind the scenes to show you why we have decided to use alternative forms of energy to back up the power at Shriram Panorama Hills, 

For your diesel generator set, you should be checking the coolant levels each month and replenishing it, should it be getting low. It will also important to ensure that your exhaust is being drained and that the drive belt is being checked to ensure that it isn’t wearing down. If needed, you can change coolant and oil at this time, in addition to the filters in the system.

By keeping up on these items, you can keep your generators at peak performance. That way, when you need them the most, you can ensure that they are going to operate properly.
