specific Embodiment approach

[0054] The core of the present invention is to provide a thermal system performance calculation method, a schematic flow chart of a specific implementation is as follows figure 1 As shown, it is called the first specific implementation mode, including:

[0055] S101: Obtain the performance data of the main measuring point and the performance data of the slave measuring point within a preset time period.

[0056] It should be noted that the data types of the performance data of the main measuring point and the performance data of the slave measuring point may be the same or different. Taking a thermoelectric system as an example, water vapor drives a fan through a pipe. If the main measuring point is a water vapor inlet , the slave measuring point is a fan, then the information of the master measuring point and the information of the slave measuring point that may need to be acquired are water vapor pressure and fan speed respectively. In addition, there is only one main measu...

Abstract

The invention discloses a thermodynamic system performance calculation method. The method comprises the following steps: acquiring master measurement point performance data and slave measurement point performance data in a preset time period; obtaining minimum information entropy data corresponding to the slave measurement point performance data through the master measurement point performance data and the slave measurement point performance data; determining time deviation value information through the minimum information entropy data; and calculating the performance of the thermodynamic system according to the time deviation value information. By confirming the time deviation value information, on the basis of not greatly prolonging the sampling time of the performance test, the problem that the influence of changing front-end sensor parameters due to too short sensor parameter extraction time in the performance test is not transmitted to a rear-end sensor, so that the test result is inaccurate is solved, and the thermodynamic system performance test accuracy is improved. The invention further provides a thermodynamic system performance calculation device and equipment with the beneficial effects and a computer readable storage medium.

Description

technical field [0001] The invention relates to the field of thermal system detection, in particular to a thermal system performance calculation method, device, equipment and computer-readable storage medium. Background technique [0002] The performance calculation of the thermal system of the thermal power generation unit is currently based on the data collected by the thermal power plant from multiple types of sensors such as temperature, pressure, and flow distributed in different positions of the system, and the performance of the thermal power generation unit is calculated online in accordance with relevant industry or national standards. [0003] The relevant calculation methods stipulated in the industry standard or national standard are based on the steady-state working conditions of the thermal system or a long period of time. In the actual thermal system, due to the characteristics of many thermal system components, long working medium flow channels, and complex da...
