Thank you so much.
I have another query emerging in my mind now that few Electrical Relay Protections (like unbalance protection, overload protection etc.) are only meant to open Generator Circuit Breaker and operate a lockout relay (86G1). They don't send a trip signal to turbine. As these...
I really appreciate everyone's opinion here. So, summing up the topic with below comments:
"Steam Turbine Generator should always trip (open the Generator Circuit Breaker) after actuation of reverse power under normal stop and loss of prime mover (either due to governor malfunction or actual...
Can you kindly share the relvant GE literature if possible?
Is it possible for us to generate a turbine trip in addition to generator breaker opening for low forward power protection? This will ensure that prime mover is also isolated and ensure unnecessary stress caused by reverse power?
We have recently faced some outages of our 7.6MVA Steam Turbine Generator on actuation of Reverse Power Protection. Below are some details:
1. Protection Relay SIEMENS SIPROTEC 7UM62 is installed at our Generator Breaker, 02 stages of Reverse Power Protection are enabled in it.
Setpoint: -119.3...
