Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0049] Such as figure 1 As shown, a thermal power unit start-stop and drop-out supervision method, the method includes the following steps: collecting power data of the unit; performing data extraction on the power data; performing data preprocessing on the extracted data to obtain valid data ; Store the valid data in a database; analyze the historical data in the database to determine whether the current data is an unplanned downtime event or an unplanned output reduction event.

[0050]The power data of the above-mentioned units is obtained through the RIS Energy Management Platform (referred to as RIS Platform SRT). The bottom layer of the RIS Energy Management Platform is the data source la...

Abstract

The invention discloses a thermal power generating unit start-stop and derated output supervision method, and belongs to the field of electric power engineering. The method comprises the following steps: collecting power data of a unit; performing data extraction on the power data; performing data preprocessing on the extracted data to obtain effective data; storing the valid data in a database; and by analyzing historical data in the database, judging whether the current data is a non-planned shutdown event or a non-planned descending output event or not. The thermal power generating unit start-stop and derated output supervision application technology has the advantages of rapidness, accuracy, convenience, low missing report rate, high automation level and the like.

Description

technical field [0001] The invention belongs to the field of electric power engineering, and in particular relates to a method for supervising the start-stop and power-down of a thermal power unit. Background technique [0002] The application of the remote monitoring function of thermal power units can not only be considered from an economic point of view, but also be designed in terms of safety and resource integration; combined with the centralized management of non-stop units, it can not only predict the current state through history, but also can be used for learning and Fault analysis to achieve the purpose of non-stop reduction; through the remote diagnosis center, remote suggestions and prompts can be given to prompt the unit to start and stop in an economical and safe state. The start-stop system of the unit refers to the start and stop of the unit. During the start-stop process, the metal parts will produce temperature difference, thermal deformation, and thermal s...
