Example Embodiment

[0043] Example one

[0044] like figure 1 , The present embodiment proposes one kind of electricity and water and the thermal power plant monitoring information management method, comprising the steps of:

[0045] . S1 and electrical data collection related to water-related data;

[0046] . S2 data extracting tap water pressure related data, and judges based on the stability of the corresponding pipe pressure data;

[0047] S3. Issued a safety warning information for the corresponding pipe when the pipe is in an unstable state.

[0048] In step S2, a water balance and electrical balance analysis are analyzed in accordance with the electrical data and water-related data. And preferably to the collected data preprocessing using electrical and water balance balance analysis after analysis of the collected data preprocessing;

[0049] In particular, the presence of any pre-treatment including culling pipe in the unstable state of the acquired data related to water and / or electrical ...

Example Embodiment

[0066] Example 2

[0067] like image 3 As shown, this embodiment is similar to the embodiment, and the present embodiment is in that the present embodiment is in step S2, and when there is a case where multiple similar degrees in the preset time period is higher than the set threshold, the number exceeds the predetermined amount. However, it is considered that the pipe is in an unstable state, otherwise it is in a steady state, the length of the preset time period is preferably more than 100m, i.e., the water pressure data is acquired by the frequency of 1 ms / time, and the preset time period is greater than 10s, and the predetermined amount It is preferably an integer greater than or equal to 2. The scheme is not limited in one comparison, and only when the water pressure fluctuation occurs during a period of time, it is determined that the pipe is in an unstable state, avoiding the detection error, calculating errors, or external interference.

Example Embodiment

[0068] Example three

[0069] The embodiment is similar to the embodiment, and the difference is that in the step S1 of the present embodiment, the first water pressure sensor and the second hydraulic sensor are respectively collected to collect each pipe at two terminals of each conduit. Water pressure data on both ends. like Figure 4 As shown, the first water pressure sensor and the second water pressure sensor acquire water pressure data at a frequency of 1 ms / time, respectively, each 20 ms, respectively, respectively, respectively.

[0070] In step S2, when the stability is determined to the pipe, the current time before the current time N / 2 water pressure data uses the water pressure data collected by the first water pressure sensor, ie Figure 4 The first hydraulic sensor is 1 to 10 10 water pressure data, and the current time (N / 2) +1 to N water pressure data uses the water pressure data collected by the second water pressure sensor, ie Figure 4 The second hydraulic se...

Abstract

The invention provides a power and water utilization monitoring and informatization management method for a thermal power plant. The method comprises the following steps of S1, collecting water-related data; S2, extracting pipeline water pressure data in the water-related data, and judging the stability of a corresponding pipeline according to the pipeline water pressure data; and S3, when the pipeline is in an unstable state, safety early warning information for the corresponding pipeline being sent out. According to the method, the collected water-related data is used for judging stability of the pipeline, management personnel can be informed in time when the pipeline is in an unstable state, the management personnel are helped to find fault problems in time, and meanwhile the data can serve as reference data of a fault diagnosis system to improve fault diagnosis accuracy of the fault diagnosis system.

Description

technical field [0001] The invention belongs to the technical field of data monitoring and information management of thermal power plants, and in particular relates to a method for monitoring electricity and water consumption and information management of thermal power plants. Background technique [0002] At this stage, my country generally shows a trend of diversified development in terms of power production methods, but thermal power plants, as the main body of traditional power generation, will still occupy the dominant position in my country's power generation industry for a long time to come. However, with the country's increasing emphasis on ecological and environmental issues, higher standards have been set for the production process of the traditional thermal power industry. Improving the power generation process of traditional thermal power generation and optimizing the use of production materials in the process of thermal power generation more efficiently has beco...
