Beschreibung
Zusammenfassung:	The invention discloses an optimal control system and an optimal control method for a ship power supply and steam supply linkage system by utilizing waste heat of a diesel generator. The control system comprises a sensor, a combined heat and power generation controller, and a power generation amount PID controller of a steam turbine generator. The combined heat and power generation controller obtains steam heat supply requirements and power utilization requirements of a whole ship through sensors, calculates fuel consumption of the diesel generator and a fuel boiler, sends out a fuel control signal, and sends out a set value signal to the power generation amount PID controller of the steam turbine generator at the same time, therefore, the operation conditions of equipment such as a marinediesel generator, a fuel boiler, a waste gas boiler and a steam turbine generator are controlled, and the whole-ship steam heat supply requirement and power utilization requirement are met. Comparedwith the prior art, the op
