There is no external controller for frequency control. Total load of plant is 11.5 MW, and at times there are sudden load variations of up to 0.8 MW. Could this pose a problem to the frequency control?
Hi,
We have a manufacturing facility with our power generation through 15MW STG and multiple 2MW DGs. DGs are the only machines capable of providing black start, and the STG is then synchronized afterwards. All generators are running in droop mode (STG droop: 4%, DGs droop: 5%).
In the above...
Thanks for the response Waross. My concern is that in our case even though the HP output was only 38% (this also corresponds to almost the same opening in the field), PID output had gone upto 83%. We have calibrated the HP output to the physical valve over the whole range (0-100%). Is there a...
We have a Woodward 505e installed on our 15 MW extraction steam turbine. Yesterday we noticed that when we were running at 7 MW (without extraction), the HP output was 38% while the speed PID output had gone up to 83%. Then we opened up the extraction, and as soon as we did that, speed PID...
Hello,
We've been facing a problem with our 15 MW steam turbine recently. It has Woodward 505e governor controller installed and configured in 4% droop mode, although normally it is running alone. At other times (during startup), it is synchronized to other DGs.
The problem we faced recently...
