| At present,as the enlarging of the differences between wave peak and wave valley, the units regulating load and the deep regulating load have become unarguing fact. So it is very important for steam turbines to calculate the low load works with fast speed and high accuracy. On the basic of steam turbines thermal power calculating theory, the cptimal control parameter caculating model of deep regulating load is built in this paper. Using the object of 600MW steam turbines, the caculating program is developed based on modular mind and DELPHI platform. Through the specific experiment of deep regulating load for this object, it has been verified the engineering value of this model. It provides a solid basis and accordance for steam turbines'operating safely and economically. |
