Embodiment 1

[0067] In this embodiment, a method for on-line monitoring and analysis of condenser performance is specifically provided, the method comprising:

[0068] S1: Real-time collection and storage of operation data of condenser measuring points, steam turbine measuring points and auxiliary equipment measuring points in the database; among them, condenser measuring points, steam turbine measuring points and auxiliary equipment measuring points are the existing measuring points of the power plant , through the DCS system of the power plant to realize data collection and transmission to the database.

[0069] S2: Read the database data and judge whether the current steam turbine power is greater than 60%. If it is satisfied, enter the condenser operation index acquisition; The plant allows long-term operation of the turbine power setting.

[0070] S3: Judging whether the operation index of the condenser meets the requirements, if it is satisfied, then end; if not, give a suggestion; ...

Embodiment 2

[0118] Also provided in the present invention is a computer expert system for on-line monitoring and analysis of condenser performance, the system is based on the method for on-line monitoring and analysis of condenser performance described in the above-mentioned embodiment 1, the system includes:

[0119] The sensors that are respectively arranged at each condenser measuring point, steam turbine measuring point and auxiliary equipment measuring point, the data that each sensor needs to measure is as described in Embodiment 1, and the installation position of each measuring point is set with reference to the power plant standard, here I won't repeat them here.

[0120] A data memory connected to each of the sensors in communication, the data memory receives and stores the measurement data of each sensor in real time, and relevant data of the HEI standard is also stored in the data memory.

[0121] The computing host computer connected with the data memory communicates, reads t...

Abstract

The invention discloses a method for on-line monitoring and analysis of condenser performance and a computer expert system, which belongs to the technical field of steam turbine operation monitoring in a power plant, and includes operating data of condenser measuring points, steam turbine measuring points and auxiliary equipment measuring points Real-time collection and storage to the database; read the database data and judge whether the current steam turbine power is greater than 60%, if satisfied, enter the condenser operation index acquisition; if not satisfied, end; judge whether the condenser operation index meets the requirements, If it is satisfied, it will end; if it is not satisfied, it will give suggestions; in order to achieve a more timely, intuitive and accurate understanding of the performance of the condenser by comparing the operating performance of the condenser with the performance required by the design. It saves a lot of time and energy spent by operators on collecting design and operation data during offline comparison, calculation and analysis, and provides suggestions for equipment maintenance and improvement projects during operation and major and minor repairs of units.

Description

technical field [0001] The invention belongs to the technical field of steam turbine operation monitoring in a power plant, and in particular relates to a method for on-line monitoring and analysis of condenser performance and a computer expert system. Background technique [0002] The operating performance of the existing condenser relies on the power plant operators to monitor the DCS data during operation, and based on personal and team experience offline comparison, test, calculation, analysis, and then adjust the operation and determine the need for equipment maintenance and improvement during major and minor repairs of the unit Projects, such as condenser tube side cleaning, plugging and replacement of tubes, system equipment and pipeline leak-proof vacuum and other maintenance and improvement activities. [0003] There are system measurement points and lack of design comparison data, the analysis system and data are huge and intuitive, the accuracy of analysis problem...
