Method for plotting water temperature-power output curve of generator

Abstract

The invention provides a method for plotting a water temperature-power output curve of a generator. The method is characterized by comprising the steps of: calculating a allowable largest excitation current value at a water temperature point with a certain number; setting a rated power output value as an initial power output value of the generator; calculating an excitation current value according to the power output value of the generator; increasing the power output of the generator if the calculated excitation current is larger than the allowable largest excitation current at the water temperature point with the certain number, otherwise, decreasing the power output of the generator; calculating a new excitation current value according to the new power output of the generator; obtaining the power output value of the generator corresponding to the water temperature point with the certain number when the error between the new excitation current and the allowable largest excitation current at the water temperature point is smaller than 1A; and plotting the water temperature values of all water temperature points and the corresponding power output values to obtain the water temperature-power output curve of the generator. The method provided by the invention can overcome the disadvantages in the prior art, and has the advantages of being few in input data, convenient to operate, and high in curve plotting speed.

Description

technical field [0001] The invention relates to a method for drawing a water temperature-output curve of a generator, and belongs to the technical field of calculating and drawing the water temperature-output curve in the overall design of a generator. Background technique [0002] When designing a turbogenerator, it is necessary to complete the drawing of the water temperature-output curve. The water temperature-output curve of the generator is the basic information to show the user the maximum continuous output capacity of the generator. [0003] In the past, to draw the generator water temperature-output curve, it was necessary to refer to the generator water temperature-output curve sample provided by the imported technology in the past. To draw a curve in this way, it is necessary to organize experts to discuss and decide based on the specific model. Not only is the drawing speed relatively slow, but also the shape of the curve will vary with the results of the discuss...
