Abstract

The invention provides a measuring device and method for minimum technical output force of an extraction condensing-type steamer generator set and belongs to the field of steamer machine heat supply.The problem that as for an existingmeasuring method for the minimum technical output force of the extraction condensing-type steamer generator set, the accuracy is poor or the consumed time is long issolved. An automated mode is adopted to conduct online collection on data needed for generation of a thermoelectric coupling model of the extraction condensing-type steamer generator set, and the collected data are subjected to error correction. According to the data subjected to error correction, a plurality of relation curves of the extraction condensing-type steamer generator set are fit, andthe thermoelectric coupling model of the extraction condensing-type steamer generator set is generated according to the multiple relation curves of the extraction condensing-type steamer generator set. According to the thermoelectric coupling model of the extraction condensing-type steamer generator set and the known heat load of the extraction condensing-type steamer generator set, the minimum technical output force of the extraction condensing-type steamer generator set is measured. The measuring device and method are particularly suitable for measuring the minimum technical output force ofthe extraction condensing-type steamer generator set.

Description

technical field [0001] The invention relates to a device and a method for measuring the minimum technical output of a steam turbine generator set, and belongs to the field of steam turbine heat supply. Background technique [0002] At present, in the northern part of my country, cogeneration of electricity and heat is mainly used to realize centralized heating, while the existing cogeneration of electricity and heat is usually realized by the cooperation of extraction condensing steam turbine and generator. [0003] During the heating period, a part of the steam needs to be extracted through the exhaust port of the medium-pressure cylinder of the extraction condensing turbine for heating, and this part of the steam will inevitably do work when flowing through the high-pressure cylinder and the medium-pressure cylinder, which is thermoelectric coupling. . Although this thermoelectric coupling method improves the overall economics of the extraction condensing turbo-generator ...
