Embodiment Construction

[0031] During the operation of the entire desulfurization unit, it is necessary to monitor its operation; when monitoring and evaluating a single index or a set of important indicators of the desulfurization unit, the parameter evaluation method of the desulfurization unit based on online data is used. The parameter evaluation method includes a parameter-level evaluation unit. The parameter-level evaluation unit is individually integrated through basic indicators and controlled by a computer display. The computer is connected to the data collectors installed in various places on the desulfurization device. The data collectors correspond to the acquired basic index data. One setting; the corresponding process parameters in the DCS system are used as the basic indicators.

[0032] Applying the parameter evaluation method of desulfurization unit based on online data, the specific steps are as follows:

[0033] Step 1. Classify the process parameters corresponding to the DCS syste...

Abstract

The invention discloses a desulfurization device parameter evaluation method based on online data, which comprises the following specific steps: 1, classifying basic indexes and completing a parameter-level evaluation unit; 2, establishing a mathematical model for the basic indexes and analyzing the mathematical model; 3, installing a data detection collector and setting an evaluation range; 4, determining an evaluation index allowable fluctuation range and an alarm limit value; 5, determining an evaluation rule and carrying out evaluation feedback on different working conditions; and 6, performing real-time data collection and evaluation control on the economy. According to the invention, through combined arrangement of field data acquisition and an online data platform, monitoring and early warning of desulfurization system operation with less manpower or even without manpower can be satisfied; through independent evaluation, overall and local dual control is facilitated; and throughmodeling processing, threshold division of data values and different scoring rules, distinctive evaluation is facilitated, and the applicability and applicability of actual construction are improved.

Description

technical field [0001] The invention belongs to the technical field of intelligent detection of desulfurization system operation, and in particular relates to a desulfurization device parameter evaluation method based on online data. Background technique [0002] At present, with the progress and innovative development of the power industry, exploring and building smart power plants has become a new trend in the development of power generation companies, and it is also a new trend in future energy management. The current desulfurization system operation monitoring is mainly performed by the operation personnel on duty through the DCS screen for real-time monitoring of system process parameters, operation adjustment and accident handling. The operating personnel must be very familiar with the system process, equipment operating parameters and limit values, and need to constantly browse the DCS screen to quickly identify, judge and analyze a large number of operating parameter...
