Several fast cut back(FCB) tests of the 330 MW unit in Indonesia INDRAMAYU Power Plant were presented.Based on analyzing such problems as wrong action of bypass protection system
speed overshoot of the turbines
and sharp decrease of the main steam temperature
optimization of parameters of temperature regulation control loop in high pressure bypass and generator tripping control logic of steam turbine interlocking during FCB was performed.Test results showed that
the maximum differences of temperature main and reheat steam drop for were 25 ℃ and 23 ℃
respectively.After the improvement
the regulation quality was significantly enhanced.
