The analogue control system(MCS) of Indonesia's INDRAMAYU 330 MW unit was investigated.The MCS unit coordinated control system was designed without lock-out increase and decrease function of load command
causing unstable operation of the unit.Besides
the oil combustion volume signal was not considered in the total fuel signal
leading to large disturbance in fuel control system during the oil gun operation.Therefore
the coordinated control system was optimized
and load test showed the improved MCS had good regulating quality.During the test run stage
the unit automatic input rate was 100%.When the unit ran stably
the main steam pressure deviation was within ±0.3 MPa
and the load deviation was within ±3 MW.In load varying stage
the main steam pressure deviation was within ±0.5 MPa and the load deviation was within ±5 MW.
