We have two Gas turbines based on Mark-IV control Speedtronics system. At a time we have only one of them in operation and the second serves as a cold stand by. At the time of changeover of the GTG we faced the following problem.
While doing De-synchronization of the GTG we faced the problem that none of the machines could take the load and which lead to the trip of both the machines. Both the machines were on Droop mode. is it a right practice or not to keep botht the machines in droop mode while doing the change over of the GTG.
We tried to change the operating mode of the machine from Droop to Isochronous but could not succeed. Pls let us know what could be the possible reason behind it.
