Unit boundary failover method, device, equipment and computer storage medium

Abstract

The invention discloses a thermal power generating set boundary failure switching method. The method comprises the steps of acquiring the operation boundary data of a set in real time, generating boundary codes according to boundary data and storing the boundary codes into a historical database; judging whether the boundary data meets preset normal conditions, and if not, it is indicated that theboundary is invalid, and setting the code of the failure boundary in the marker post value working condition library as the latest stored code of the failure boundary in the historical database, and marking and coding the codes of the failure boundary; and when it is judged that the failure boundary meets the preset normal condition, unlocking the mark of the failure boundary, and taking the current code of the failure boundary as the code of the failure boundary stored in the marker post value working condition library. The marker post value guidance is carried out according to the value before failure, and the guidance reference value of the marker post value working condition library is high, and the reliability is high. The invention further discloses a device, equipment and a computerstorage medium based on the method.

Description

technical field [0001] The invention relates to the field of thermal power unit optimization, in particular to a thermal power unit boundary failover switching method. The invention also relates to a thermal power unit boundary failure switching device, equipment and computer storage medium. Background technique [0002] In the process of optimizing the economics of thermal power units, it is necessary to use the benchmark data in the benchmark value working condition database as the benchmark for processing, and the operating boundary of thermal power units is an important part of the benchmark working condition database. The accuracy of the measuring points greatly affects the applicability of the benchmark value case library. [0003] When the current thermal power unit optimization software encounters a boundary failure, the method adopted is mainly: the benchmark value guidance function of the operation optimization software is out of operation, and the operating perso...

Problems solved by technology

[0004] This method has obvious disadvantages in actual implementation: some failed operating boundaries often remain stable in a short period of time in actual operation, and the fluctuation is small. Therefore, when a short-term failure occurs, the value of the failed operating boundary before failure It still has a certain reference value, and easily exiting the benchmark value guidance function of the operation optimization software will greatly reduce the reference value of the benchmark value working condition library, and the reliability is low
