Description

Technical Field

[0001] The present invention relates to the technical field of equipment detection, and in particular to a method for intelligently determining faults of voltage regulating equipment, voltage regulating equipment and a storage medium. Background Art

[0002] The gas transmission and distribution system consists of gate stations, transmission and distribution pipelines, pressure regulators, operation management facilities and monitoring systems. In ensuring the safe and effective use of natural gas and efficient transmission and distribution, the gas pressure regulator plays a role in gradually adjusting the higher upstream pressure to a lower pressure so that different types of users can use gas safely and effectively. In the existing technology, the gate stations and high and medium pressure regulating stations in the urban gas transmission and distribution system basically realize SCADA data monitoring of operating conditions such as pressure, temperature, flow and valve position, and some stations have realized remote pressure regulation and flow limitation. However, most of the medium and low pressure gas pressure regulating equipment in service are purely mechanical pressure regulating, which mainly relies on manual regular inspection and maintenance to determine whether the equipment has abnormal working conditions such as filter blockage, pressure regulator failure, equipment leakage, etc., and lacks analysis of users' gas usage patterns. In order to strengthen the management of pressure regulating equipment, some pressure regulating equipment will be retrofitted with data collectors in the later stage, and the changes in the operation status of the pipeline network will be determined by combining manual data analysis.

[0003] The above-mentioned operation mode has the following defects: First, there is a lack of intelligent monitoring system in the pressure regulating system, and it is impossible to remotely monitor the equipment in real time; abnormal working conditions can only be discovered through periodic inspections by personnel or user reports of faults, and it is impossible to effectively form an active management mode of "early warning". Second, various data analyses mainly rely on manual operations, which requires high experience of operators; and a large number of equipment easily leads to the lack of comprehensive management and analysis of operating parameters, which is not conducive to the optimization of equipment performance and has high maintenance costs.

[0004] Therefore, there is an urgent need to provide a method for intelligently determining faults of a voltage regulating device, a voltage regulating device and a storage medium to solve the above problems. Summary of the invention

[0005] The main purpose of the present invention is to provide a method for intelligently determining faults of a voltage regulating device, a voltage regulating device and a storage medium, aiming to solve the existing technical problems.

[0006] To achieve the above object, the present invention provides a method for intelligently determining faults of voltage regulating equipment, comprising:

[0007] Classify users according to their types, collect the outlet pressure data of the pressure regulating equipment in the first time period according to the user classification, and determine the main gas consumption time period;

[0008] Detect whether the outlet pressure data in the first time period is within the pressure regulation accuracy range, and analyze and determine the corresponding fault type;

[0009] Analyze the inlet pressure data of the pressure regulating equipment within the first time period, and compare the inlet pressure data to determine a fault alarm.

[0010] Further, classify according to the user type, collect the outlet pressure data of the pressure regulating equipment within the first time period according to the user classification, and determine the main gas consumption time period, including,

[0011] If it is for a non-residential user alone, directly analyze all the outlet pressure data of the pressure regulating equipment collected within a day;

[0012] If it is not for a non-residential user alone, analyze the outlet pressure data of the pressure regulating equipment at a time interval of 30 minutes.

[0013] Further, the steps for analyzing the outlet pressure data include,

[0014] When A = P 出口 i+1 -P 出口 i > 0, let A i = 1;

[0015] When A = P 出口 i+1 -P 出口 i < 0, let A i = -1;

[0016] When A = P 出口 i+1 -P 出口 i = 0, let A i = 0;

[0017] Analyze the relationship between A i and time t. When |A i+1 -A i |> 0, mark this time point;

[0018] When |A i+1 -A i | = 0, stop marking;

[0019] Perform data fitting of A i —t i for the marked first time period. If the fitted curve conforms to a sine function or a cosine function, mark this time period as the main gas consumption time.

[0020] Further, detect whether the outlet pressure data within the first time period is within the pressure regulation accuracy range, and analyze to determine the corresponding fault type, including,

[0021] When it is detected that the outlet pressure is not within the pressure regulation accuracy range, the outlet pressure analysis is started to obtain a first area where the outlet pressure exceeds the upper accuracy limit and a second area where the outlet pressure exceeds the lower accuracy limit in the first time period;

[0022] If the first area is not equal to 0 and the second area is not equal to 0, then inspect the regulator pilot, signal tube or needle valve;

[0023] If the first area is equal to 0 and the second area is less than 0, then inspect the valve port, valve port gasket, signal tube, valve stem and spring;

[0024] If the first area is greater than 0 and the second area is equal to 0, check whether the voltage regulator is appropriately selected.

[0025] Furthermore, the analyzing of the inlet pressure data of the pressure regulating device in the first time period and comparing the inlet pressure data to determine the fault alarm include:

[0026] When the inlet pressure exceeds the set high limit alarm value, the system will issue an alarm that the pipeline gas supply pressure is unstable / the upstream pipeline has a fault;

[0027] When the inlet pressure is lower than the set lower alarm value, and the instantaneous pressure drop of three consecutive inlet pressures is greater than 0.05MPa / min, the analysis of the instantaneous pressure drop is started.

[0030] The fourth time period, the fifth time period, ... the nth time period are analyzed in turn. When the instantaneous pressure drop in the nth time period is not equal to 0 and the instantaneous pressure drop in the nth time period is △p i+n The time period t corresponds to △p i+n =at+b, it is determined that the upstream gas is stopped or there is serious water blockage or pipeline rupture; when the instantaneous pressure drop in the nth time period meets the time period t △p i+n = b, it is determined that leakage / third-party damage occurs near the pipeline inlet.

[0031] Furthermore, it also includes:

[0032] Pressure analysis before and after the filter: when the pressure difference before and after the filter is ≥30kpa, the system will issue a filter blockage alarm to remind you to clean or replace the filter;

[0033] Cut-off valve judgment: when the cut-off valve is actuated, an outlet pressure overpressure alarm signal is issued and analyzed. When the outlet pressure is greater than the preset cut-off pressure, it is determined that the pressure regulator is not working, and a reminder is given to inspect the diaphragm / valve port, clean the valve port or replace the valve gasket.

[0034] Furthermore, it also includes:

[0035] After each fault alarm, the system will input information and confirm the on-site fault point and operation;

[0036] The voltage regulating equipment information is entered, classified according to the manufacturer and model of the equipment, and various alarm information of the equipment is counted; when a fault occurs, the system compares the same type of equipment and the same type of data at the same time, and gives the corresponding fault probability, providing operational guidance for equipment maintenance personnel.

BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Figure 1 The figure is a flow chart of the intelligent fault determination method for voltage regulating equipment of the present invention. DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0046] See also Figure 1 The present invention provides a method for intelligently determining faults of voltage regulating equipment, comprising:

[0047] S10: Classify users according to their types, collect outlet pressure data of the pressure regulating equipment in the first time period according to the user classification, and determine the main gas consumption time period;

[0048] Before this step, it is also involved to determine the peak gas consumption time; currently, gas users are mainly divided into residential users and non-residential users (referring to industrial users, commercial users and public welfare users, etc.) according to the nature of the users. Among them, some non-residential users are supplied with gas by a single pressure regulating device due to large gas consumption or the setting of surrounding pipelines. Under the premise of normal operation of pressure regulation, when all users corresponding to the pressure regulating device are non-residential users, the outlet pressure of the pressure regulating device generally fluctuates smoothly within the pressure stabilization accuracy range and the frequency of fluctuation is high, and the gas consumption time is highly consistent with the gas consumption behavior of the users; when all users corresponding to the pressure regulating device are residential users or non-residential and residential users are mixed, due to the mutual influence of gas consumption and gas consumption behavior of different types of users, the fluctuation of outlet pressure is generally relatively gentle and low in frequency.

[0049] The determination of peak gas consumption time is mainly to provide a reference for pipeline network operation and to prepare for the subsequent intelligent pressure regulation according to the user's gas consumption time. There are three reasons: ① The peak and trough of gas consumption are obtained to facilitate the adjustment of pipeline operation pressure, increase the outlet pressure during peak periods, and reduce the pressure regulating outlet pressure during trough periods, thereby reducing the overall leakage of the pipeline network; ② Analyzing the gas consumption time is conducive to the arrangement of our emergency operations. The gas outage operation time is arranged during the trough period of gas consumption to reduce the impact on users; ③ Analyzing the gas consumption time is conducive to scheduling operations. During peak periods, the demand for gas dispatched from upstream increases, and during trough periods, the amount of gas lifted from upstream is reduced.

[0050] In one embodiment, the classification according to user type, collecting the outlet pressure data of the pressure regulating device in the first time period according to the user classification, and determining the main gas usage time period include:

[0051] If it is for supplying non-residential users alone, directly analyze the outlet pressure data of all pressure regulating equipment collected in one day;

[0052] If it is not for non-residential users alone, analyze the outlet pressure data of the voltage regulating equipment at 30-minute intervals.

[0053] In one embodiment, the steps of analyzing the outlet pressure data include,

[0054] When A = P 出口 i+1 -P 出口 i > 0, let A i = 1;

[0055] When A = P 出口 i+1 -P 出口 i < 0, let A i = -1;

[0056] When A = P 出口 i+1 -P 出口 i = 0, let A i = 0;

[0057] Analyze the relationship between A i and time t. When |A i+1 -A i |> 0, mark this time point;

[0058] When |A i+1 -A i | = 0, stop marking;

[0059] For the first marked time period, perform data fitting of A i —t i data. If the fitted curve conforms to a sine function or a cosine function, mark this time period as the main gas consumption time.

[0060] When fitting for the first time, it is necessary to judge the data of the equipment for 21 days (empirical value, 21 days can basically reflect the gas consumption law) to determine the overlapping time period as the main gas consumption time. For the determined time, perform data fitting comparison and correction every month.

[0061] S20: Detect whether the outlet pressure data in the first time period is within the voltage regulation accuracy range, and analyze to determine the corresponding fault type;

[0062] In one embodiment, detecting whether the outlet pressure data in the first time period is within the voltage regulation accuracy range and analyzing to determine the corresponding fault type includes,

[0063] When it is detected that the outlet pressure is not within the pressure regulation accuracy range, the outlet pressure analysis is started to obtain a first area where the outlet pressure exceeds the upper accuracy limit and a second area where the outlet pressure exceeds the lower accuracy limit in the first time period;

[0064] If the first area is not equal to 0 and the second area is not equal to 0, then inspect the regulator pilot, signal tube or needle valve;

[0065] If the first area is equal to 0 and the second area is less than 0, then inspect the valve port, valve port gasket, signal tube, valve stem and spring;

[0066] If the first area is greater than 0 and the second area is equal to 0, check whether the voltage regulator is appropriately selected.

[0067] According to the requirements of "Town Gas Pressure Regulator" GB 27790-2020, the pressure regulator should meet the pressure stabilization accuracy requirements, which are specifically divided into AC1, AC2.5, AC5, AC10, and AC15. The maximum allowable relative deviations are ±1%, ±2.5%, ±5%, ±10%, and ±15%, respectively. Each device can be set within the system accuracy range [P a ,P b ], common abnormal conditions mainly include outlet pressure drop and outlet pressure fluctuation, the corresponding conditions are as follows:

[0068]

[0069] S30: Analyze the inlet pressure data of the pressure regulating device in the first time period, and compare the inlet pressure data to determine a fault alarm.

[0070] In one embodiment, the analyzing the inlet pressure data of the pressure regulating device in the first time period and comparing the inlet pressure data to determine the fault alarm includes:

[0071] When the inlet pressure exceeds the set high limit alarm value, the system will issue an alarm that the pipeline gas supply pressure is unstable / the upstream pipeline has a fault;

[0072] When the inlet pressure is lower than the set lower limit alarm value, and the instantaneous pressure drop of three consecutive inlet pressures is greater than 0.05MPa / min, the analysis of the instantaneous pressure drop is started. Specifically, when the inlet pressure is lower than the set lower limit alarm value, and the instantaneous pressure drop of three consecutive inlet pressures is greater than 0.05MPa / min, the analysis of the instantaneous pressure drop is started. i (△p i =p i -p a ) is greater than 0.05MPa / min, start the i ① If there is a gas outage or severe water blockage or pipeline rupture in the upstream, the pressure in the pipeline will gradually decrease over time; that is, as t increases, the pressure drop △pi Gradually rising, the system sends out an upstream gas stop / water blockage / pipeline break alarm signal. ② If a leak occurs near the inlet end or a third party damages it, the material at the leak point will be lost, the local density will decrease, and the pressure will drop. At the same time, the downstream pressure will also drop. As the leak prolongs, the pressure in the pipeline tends to be stable, and the instantaneous pressure drop in the pipeline tends to be stable.

[0073] In one embodiment, the instantaneous pressure drop analysis step includes:

[0074] When the inlet pressure in the first time period is lower than the normal pressure value of the pipeline network operation and the instantaneous pressure drop in the first time period is greater than 0.05MPa / min; and when the inlet pressure in the second time period is lower than the normal pressure value of the pipeline network operation and the instantaneous pressure drop in the second time period is greater than 0.05MPa / min; and when the inlet pressure in the third time period is lower than the normal pressure value of the pipeline network operation and the instantaneous pressure drop in the third time period is greater than 0.05MPa / min; the system sends out an alarm signal, starts analysis, and enters the second step of analysis;

[0075] The fourth time period, the fifth time period, ... the nth time period are analyzed in turn. When the instantaneous pressure drop in the nth time period is not equal to 0 and the instantaneous pressure drop in the nth time period is △p i+n The time period t corresponds to △p i+n =at+b, it is determined that the upstream gas is stopped or there is severe water blockage or pipeline rupture. When the instantaneous pressure drop in the nth time period meets the time period t, △p i+n =b (b is a constant), it is determined that leakage / third-party damage has occurred near the pipeline inlet.

[0076] In one embodiment, the voltage regulating equipment fault intelligent determination method further includes:

[0077] Pressure analysis before and after the filter: when the pressure difference before and after the filter is ≥30kpa, the system will issue a filter blockage alarm to remind you to clean or replace the filter;

[0078] Cut-off valve judgment: when the cut-off valve is actuated, an outlet pressure overpressure alarm signal is issued and analyzed. When the outlet pressure is greater than the preset cut-off pressure, it is determined that the pressure regulator is not working, and a reminder is given to inspect the diaphragm / valve port, clean the valve port or replace the valve gasket.

[0079] In one embodiment, the intelligent method for determining faults of voltage regulating equipment further includes: after each fault alarm message, the system performs information entry to confirm the fault point and operation on site;

[0080] The voltage regulating equipment information is entered, classified according to the manufacturer and model of the equipment, and various alarm information of the equipment is counted; when a fault occurs, the system compares the same type of equipment and the same type of data at the same time, and gives the corresponding fault probability, providing operational guidance for equipment maintenance personnel.

[0081] In one embodiment, the intelligent method for determining faults of pressure regulating equipment further includes leakage analysis: when a leakage signal is detected, an alarm signal is issued to remind the operator to inspect the sealing material and the valve.

[0082] Access control alarm analysis: When the access control opening signal is detected, an alarm message is issued to remind that the voltage regulating cabinet door is opened; start the timing, and when T>1h, remind the equipment door is not closed securely.
