The customer obviously doesn't want to buy any more of this expensive electricity than is absolutely necessary. Safe operation dictates The mill electrical deficit is an important concept to grasp when implementing RTP tie-line control. The RTP tie-line control algorithm uses prioritized constraints to define a safe operating envelope. Using this constraint boundary, the system herds the turbine into a safety envelope while the tie-line control function works. Condenser vacuum is low.
Purchase power is at low limit.
TG2 160-psig extraction flow is high. TG2 throttle flow is high. Total power boiler steam generation is very high. 900-psig header pressure is very low. Purchased power is at a high limit.
