More than 99% starting reliability and less than 6 0×10 -3 operation faulty ratio of diesel generator set for nuclear applications are stipulated in IEEE Std. 387-1995.In order to ensure the operation reliability and stability of diesel generator set,not only QA and QC procedures are followed strictly during manufacturing,installation and commissioning,but also feasible and reliable means and measures of fault detection are necessary in operation period.
A program of an automatic control system and the principles of operation of the ship diesel-generator power station are proposed, The working theory and the design method of the major components of control equipment together with the test on the system are described.
Using the automatic system of marine diesel-generator as a control object, the author builds up marine diesel-generator control model and designs the excitation module by software MATLAB. The excitation system of diesel-generator is a brushless compound excitation system.
Under the combined controllers of neural network and PID control system,an invert dynamic model of marine diesel engine generator is obtained through continuous learning of the neural network controller. And gradually,the neural network controller has main control effect on the system.
