The governor of steam turbine (Kawasaki) is swing even though the sliding pressure control mode is on. And,there is a "KW Limit" alarm from the woodward 505 governor control unit. If the setting parameter of woodward 505 remain unchanged. what is the root cause to governor swing? and, Why the governor control unit generated alarm "Kw limit" while increased the output ramp and the actual kw output of ST generator did not reach the kw limit about 38MW?
When, the Generator kw limit is 41.25kw
pls. advise
