Problems solved by technology

[0005] There is no distinction between pipeline emergency deployment capacity and peak shaving capacity. The existing technology is to directly obtain the sum of emergency deployment capacity and peak shaving capacity, which is only applicable to the case of a single pipeline, but not suitable for complex pipelines with many pipelines There are many branch lines, many pressure control points, and various regional pipelines can complement each other

Embodiment 1

[0045] Take 6 users A, B, C, D, E, and F in the pipe network as an example. Among them, the fluid consumption of A, B, C, and D is more than 500,000 cubic meters per day, which is a typical user.

[0046] It is now necessary to obtain the pipeline peak-shaving capacity on December 2, 2016, December 2016, the fourth quarter of 2016, and one year in 2016, based on the data actually recorded by the pipeline network.

[0047] For the peak shaving capacity of the pipeline on December 2, 2016, first obtain the first unevenness coefficient of each typical user, according to the formula first day unevenness coefficient = (the maximum value of the fluid volume used by the user per hour - the user per hour Average amount of fluid used) / Average amount of fluid used by the user per hour. For user A, the maximum amount of fluid used per hour by the user within 24 hours on December 2, 2016 was 2 million cubic meters per day, and the average fluid volume per hour used by the user within 24 h...

Embodiment 2

[0052] Take 6 users A, B, C, D, E, and F in the pipe network as an example. Among them, the fluid consumption of A, B, C, and D is more than 500,000 cubic meters per day, which is a typical user.

[0053] It is now necessary to obtain the pipeline peak-shaving capacity on December 2, 2017, December 2017, the fourth quarter of 2017, and within one year of 2017. Since the current time is July 27, 2017, December 2, 2017 The peak-shaving capacity of pipelines in Japan, December 2017, the fourth quarter of 2017, and one year in 2017 is the peak-shaving capacity of pipelines in the future. Therefore, according to the existing data, the corresponding value for the preset time period range in the future is obtained. The average value of the first uneven coefficient of the preset time period that has occurred, that is, the corresponding data of December 2, 2016, December 2016, and the fourth quarter of 2016 are obtained based on the data actually recorded by the pipeline network. , the...

Abstract

The invention discloses a method for determining peak shaving capacity of a pipeline, and belongs to the field of pipelines. The method comprises the following steps that a plurality of first non-uniform coefficients that the maximum use fluid amount of all typical users deviates from the average use fluid volume within the preset period in a pipe network are obtained, each first non-uniform coefficient is equal to (the maximum use fluid amount of the users-the average use fluid volume of the users) / the average value of each first non-uniform coefficient, the product of the average value of the first non-uniform coefficients and the fluctuation coefficient serves as a second non-uniform coefficient of the whole pipe network, and the product of the second non-uniform coefficient and the total use fluid quantity average value of all users of the pipe network is used as a pipeline peak shaving capacity. According to the method, the first non-uniform coefficients and the second non-uniform coefficient are obtained, so that the network is obtained under the condition that the use demand of the users is the largest, and the peak shaving capacity of the pipeline in the preset time periodrange can be obtained.

Description

technical field [0001] The invention relates to the field of pipelines, in particular to a method for determining the peak-shaving capacity of pipelines. Background technique [0002] With the popularity of pipelines, fluids such as water, gas, and oil are transmitted to various users through a single pipeline or complex pipelines. The user's demand for water, gas, oil and other fluids will fluctuate at different times and seasons. For example, the user's demand for natural gas fluctuates in a wave-shaped curve within a day, and the time of greatest demand is usually at noon, Evening and early morning. The peak shaving capacity refers to the surplus transmission capacity that needs to be reserved in order to meet the demand fluctuations of the user end in different time periods. Therefore, the determination of the peak shaving capacity is of great significance for the management, control and improvement of the pipeline. [0003] The method for determining the peak-shaving...
