Abstract

Paiton Power Plant Unit 7 & 8 operated by PT. IPMOMI (International Power Mitsui Operation and Maintenance Indonesia) are one of the companies that uses modern technology which the control system is DCS (Distributed Control System). All of the control systems are integrated in DCS, especially temperature control system in reheater. Reheater is one of the component of power plant which used for increasing the steam temperature coming from HP Turbine (High Pressure Turbine) used again for rotating the turbine blades of IP Turbine (Intermediate Pressure Turbine) and LP Turbine (Low Pressure Turbine). The steam temperature has range point of temperature (5400C). When the temperature raises over its set point value the temperature must be decreased by desuperheater to spray water through the steam line before the reheater. Referring to P & I Diagram and logic diagram of temperature control system at reheater final project �Simulation of Temperature Control System at Reheater in PLTU Paiton Unit 7 & 8� was build with Visual Basic 6.0 . This simulation was verified by comparing the data of final reheat outlet temperature from simulation and the data from power plant. The comparison of data from simulation and data from power plant on normal operation shows that the simulation interpretes the temperature control sysem at reheater without distubances to the system. The result is that error average of final reheat outlet temperature at data from simulation and power plant is 0.72 %. Keyword : Power Plant, Reheater, Desuperheater, Simulation
