Description

A system for determining and providing indicators of reliability and continuity of water supply and sanitation networks

Description of the invention

The invention relates to the field of urban water supply and sanitation, and is intended to determine and ensure reliability and uninterrupted operation of water supply and sanitation networks in accordance with the requirements of No. 416-FZ “On Water Supply and Sanitation”.

The known method of decomposition and equivalentization of the sewer network, designed to determine the relative volume of untreated wastewater discharged to the surface due to accidental failures of individual sections. The technique boils down to the formal replacement of the network with one dummy equivalent channel, the reliability parameters of which are calculated from the known failure and restoration rates of the sections (see Yermolin Yu.A., Alekseev M.I. Method of decomposition and equivalent of the sewer network // Water Supply and Sanitary Technique. 2012. No. 11).

The decomposition and equivalentization method has the following disadvantages:

1. Limited scope, because it:

- allows you to calculate only one indicator - the security of flow allocated by the network. At the same time, it is not possible to determine probabilistic reliability indicators, such as continuity, which, in accordance with the Federal Law of 07.12.2011 N 416-ФЗ “On Water Supply and Sanitation”, are related to the target indicators of organizations' activities;

- does not allow to evaluate the effectiveness of the device jumpers between individual sections, because Designed to calculate the security of the network only "tree" configuration. At the same time, this method of increasing reliability is known and widely used in practice, for example, loopback of a tunnel collector along the Fontanka River in St. Petersburg;

- does not allow to calculate the security of the flow allocated by the network in partially-operational states, i.e. in case of failure of individual network sections.

2. High error, because in order to simplify it, a number of assumptions are introduced that significantly underestimate the accuracy of the calculations.

The closest analogue to the claimed invention is a "Device for analyzing the reliability of pipelines of the city drainage network", taken as a prototype, equipped with a primary information processing unit, a unit for collecting and processing information about structural damage and a unit for collecting and processing information about functional changes in pipelines, inputs of connected to the outputs of the filtering block of parameters for selecting potential sanitation facilities, and the outputs to the inputs of the ranking block of potential san units, filtering blocks of reliability parameters, filtering parameters for selecting potential sanitation facilities, ranking potential sanitation facilities are sequentially interconnected, and ranking blocks according to accident criteria, analyzing and filtering primary information and operation requests, selecting potential sanitation facilities by inputs are connected in parallel to the outputs primary information processing unit, and outputs to the inputs of the filtering block reliability parameters, to the input of which the outputs of the block are also connected boron and accumulation of information about the accident rate of pipelines and the unit for collecting information on inventory. At the same time, the unit for collecting and processing information about structural damage to pipelines is made in the form of parallel cells connected to the input of the unit for collecting and processing information on cracks, types of damage, the presence of corrosion deposits and abrasive wear, the outputs of which are connected to the output of the unit. Also, the block of functional changes in pipelines is made in the form of parallel connected to the input of the block cells for collecting and processing information about the presence of displacement of pipes, about drawdowns of the tray, about violations of the initial shape of the pipes, about the presence of sediment and bio-formations, outputs connected to the output of the block (see RF patent No. 2237784 (priority of March 25, 2003) “Device for analyzing the reliability of pipelines of a city drainage network”).

A device for analyzing the reliability of pipelines in a city drainage network has a limited scope, since it is intended only for collecting and analyzing reliability indicators (failure rates) of pipelines (i.e., individual elements of drainage networks) and cannot be used to assess the reliability of the entire network, i.e. to. it does not allow determining probabilistic reliability indicators in the form of the probability that the entire network is in time at time t in the absence of failures of its sections, the probability of the network being in partially-operational states (which are not network failures) when the j-th section at time t is in the state of failure , and etc.

In addition, without determining the probability indicators of reliability it is not possible to determine the technological indicators in the form of:

- the volume of water discharged by the network during the estimated period of operation t when it is in a healthy state, etc .;

- in the form of the volume of emergency discharge of untreated wastewater due to accidents and clogging of the j-th site, etc .;

- in the form of an emergency discharge of untreated wastewater due to accidents and clogging of the j-th section, the volume of water discharged by the network during the estimated period of operation t when it is in a partially-operational state under conditions when the network configuration allows changing the flow distribution due to accidents and blockages of the j-th section.

For this reason, it is not possible to use a device to determine one of the target indicators of the activities of organizations carrying out water disposal (reliability and uninterrupted water disposal, in accordance with the requirement of Article 39 N 416-ФЗ “On Water Supply and Water Disposal”), since it allows you to determine only single indicators reliability (accident rates in the form of failure rate) of pipes and sections, and not indicators of reliability and uninterrupted operation of the entire system as a whole. The principal difference between the results of assessing the reliability of network sections and the entire network as a whole is:

- the absence of a direct relationship between the failure of one or more sections (partially operational states) with the failure of the entire network, because the failure of one or more sections does not always lead to the failure of the entire network due to its configuration, the presence of jumpers, regulatory volumes, etc .;

- various evaluation criteria, as the reliability of network sections is assessed by failure rates, and the reliability of the entire network by probabilistic and technological reliability indicators.

The objective of the present invention is to expand the scope of the device, in which it can be used not only to assess the accident rates of individual sections of networks, but also the probability indicators of reliability of the entire network as a whole.

The problem is solved so that in the known device, including the primary information processing unit, in accordance with the present invention, the primary information processing unit is made in the form of parallelly connected to the input of the unit, at least, information input cells by the number of sections n, by the lengths of sections lj, diameters of sections D _j , expenses of sections q _{j of the} network, where 0 <j≤n, duration of the calculation period t, reliability indicators of wells, reliability indicators of pipes or pipe materials, the outputs of which are connected to the outlet block house.

In addition, the system is additionally equipped with:

- a block for calculating the reliability indicators of network elements, made in the form of cells parallel to the input of the block of cells for calculating the reliability indicators of pipes, calculating the intensities of disconnecting sections, calculating the intensities of repairing sections, calculating complex indicators of maintainability of sections, the outputs of which are connected to the output of the block, while the output of the calculation cell reliability indicators of pipes connected to the input of the cell for calculating the intensities of disconnecting sections, and the outputs of the cell for calculating the intensities of repair of sections and I eyki calculation sections off intensities connected to the input of the cell calculation of complex parameters maintainability sites;

The output of the primary information processing unit is connected to the input of the units for calculating the reliability indicators of network elements, the output of the unit for calculating the reliability indicators of network elements is connected to the input of the unit for determining the probability indicators of network reliability.

According to the information available to the authors, the distinguishing features No. 34, 37 are known in the technical literature, and the rest are not known, which meets the patentability criterion of “novelty”.

The combined use of the indicated distinctive features in the claimed device allows to obtain a positive effect - expanding the scope, which consists in the fact that it is possible to use the system to determine not only individual reliability indicators (accident indicators in the form of failure rate) of pipes and sections, but also reliability indicators and uninterrupted operation of the entire system as a whole in the form of the probability of finding the network at time t in a working state, the probability of finding the network at time t in part o-working condition. This is made possible through the combined use of the distinctive features 1-5, 38, 37, 36, 35, 34, 33, 32, 20-31, 19, 18, 17, 1-2, 4, 6-7, 9-14, 17-40.

In addition, the ability to determine probabilistic reliability indicators will allow to determine technological indicators in the form of:

- the volume of water discharged by the network during the estimated period of operation t when it is in a healthy state, etc. This becomes possible due to the combined use of the distinctive features 1-5, 8, 15-37, 46-47;

This is made possible through the combined use of the distinctive features 1-3, 5, 8, 15-37, 42-45.

Thus, all the hallmarks are essential.

The system proposed by the authors is structurally different from the prototype. In FIG. 1 presents a diagram of the proposed “System for determining and providing indicators of reliability and uninterrupted operation of water supply and sanitation networks”, in FIG. 2 - the results of assessing the probability and technological reliability indicators using the proposed system as an example of a real drainage network of 13 sections of asbestos-cement pipes, when during an accident and clogging of the j-th section, the emergency discharge rate of untreated sewage is q _j , in FIG. 3 - the same when, during an accident and clogging of the j-th section, the emergency discharge rate of untreated wastewater is equal to q _{j mod} defined in the cell of the drainage network simulation, in FIG. 4 is the same when plastic pipes are applied.

The system contains (see Fig. 1):

- block 1 of the primary processing of information;

- block 2 calculation of reliability indicators of network elements;

- block 3 determine the probability indicators of network reliability;

- block 4 for determining technological indicators of the reliability of the drainage network.

At the same time, the output of the primary information processing unit 1 is connected to the input of the unit 2 for calculating the reliability indicators of the network elements and the block 4 for determining the technological indicators of the reliability of the drainage network. In addition, the output of block 2 for calculating the reliability indicators of network elements is connected to the input of block 3 for determining the probability indicators of network reliability, the output of which is connected to the input of block 4 for determining the technological indicators for reliability of the drainage network.

Block 1 of the primary information processing is made in the form of at least parallel to the input of the block of at least the information input cell 5 by the number of sections n, information input cell 6 by the lengths of sections l _j , information input cell 7 by the diameters of sections D _j , input cell 8 information on costs portions network q _j, where 0 <j≤n, cell 9 input information on the duration of the calculation period t, the cell 10 entering information on reliability indicators wells, the cells 11 input information in terms of the reliability of pipes and / or pipe materials, yields otorrhea attached to the output unit 1.

A development option is possible when it is necessary to determine the technological indicators of the reliability of a network equipped with jumpers between individual sections. In this case, the network configuration is different from the “tree-like" one and in the event of an accident and clogging of the j-th section, the emergency discharge rate of untreated sewage will not be equal to the discharge of this section. To determine it, it is necessary to simulate an accident in this area. In this case, the unit 4 for determining technological indicators of the reliability of the drainage network is additionally equipped with a cell modeling network 23.

The system operates as follows.

In block 1 of the collection of primary information (Fig. 1) through external communication channels (not shown), the following information about the drainage networks is entered:

- by the number of sections n - in cell 5;

- according to the lengths of the sections l _j - in cell 6;

- by the diameters of the sections D _j - in cell 7;

- according to the costs of the sections q _j - in cell 8, where 0 <j≤n;

- by the duration of the settlement period t - in cell 9;

- according to the reliability indicators of wells - in cell 10;

- in terms of reliability of pipes or pipe materials - in cell 11.

In block 2 of the calculation of indicators of reliability of network elements is calculated:

- indicators of pipe reliability - in cell 12, which is configured to determine the failure rate λ _{failure j} and blockages λ _{blockages j} of drainage networks according to the dependencies given in the claims depending on the material and their diameter D _j . For example, with the diameter of the asbestos-cement pipes of the j-th section D _j = 0.2 m, the failure and clogging intensities are equal to λ _{failure j} = 0.048 · D _j ^-0.8 = 0.048 · 0.2 ^-0.8 = 0.174 (1 / (year · km))

and λ _{blockage j} = 0.16 · D _j ^-1.2 = 0.16 · 0.2 ^-1.2 = 1.104 (1 / (year · km)), see the evaluation results for section 12-13 in FIG. 2. In addition to the failure rates in cell 12, the duration of pipe repair is determined by the formula:

where t _{rem j} - the duration of repair of pipes of the j-th section, hours; D _j - the diameter of the pipes of the j-th section, mm For example, at D _j = 200 mm, t _{rem j} = (8760 / (8760 / (485 · 0.001 · 200-504 · (0.001 · 200) ² -27)) = 49.84 hours. Information on the materials and diameters of the pipes is received from block 1 of the primary information processing (cells 7 and 11.) The present invention does not exclude not calculating, but entering the finished information of the reliability indicators of the pipes through cell 11 of block 1. In this case, in the cell 12, the entered values are assigned;

. Если участок имеет длину, например, l_j=0,08 км и дополни тельный смотровой колодец, то λ_{уч j}(t)=(λ_{отказ j}+k₁·t^a1)·l_j+2*λ_k=λ_{уч j}(8760)=(0,17+5·10^-9·8760^1.63)·0,08+2*0,028=0,0707 (1/год). При продолжительности эксплуатации меньше нормативного срока службы, длине участка асбестоцементных труб l_j=0.05 км, интенсивности отказов колодцев λ_к=0,028 1/год интенсивность его отключения в зависимости от учитываемых факторов равна

- disconnection intensities of sections - in cell 13, which is configured to determine the intensity of disconnections of sections λ _{u j} (t) according to the dependencies given in the claims depending on the length of sections l _j , duration of the calculation period t, reliability indicators of wells λ _k (information comes from cells 6, 9, 10) and pipe reliability indicators λ _{blockage j} and / or λ _{failure j} (information comes from cell 12 or from cell 11). For example, when the length of the asbestos-cement pipe drainage network section is l _j = 0.05 km, the well failure rate is λ _k = 0.028 1 / year, the operating time is 1 year t = 8760 h, the shutdown rate depending on the factors taken into account is

. If the section has a length, for example, l _j = 0.08 km and an additional viewing well, then λ _{uch j} (t) = (λ _{failure j} + k ₁ · t ^a1 ) · l _j + 2 * λ _k = λ _{uch j} (8760) = (0.17 + 5 · 10 ^-9 · 8760 ^1.63 ) · 0.08 + 2 * 0.028 = 0.0707 (1 / year). When the duration of operation is less than the standard service life, the length of the section of asbestos-cement pipes l _j = 0.05 km, the failure rate of wells λ _k = 0.028 1 / year, the shutdown rate depending on the factors taken into account is

(1 year). Similarly, calculations are performed taking into account λ _{blockage j} and λ _{blockage j} + λ _{failure j.} For example, in FIG. 2 (section 12-13) for asbestos-cement pipes l _12-13 = 0.1134 km, λ _{failure 12-13} = 0.174 1 / (year • km), λ _{block 12-13} = 1.104 1 / (year • km),

For example, with the diameter of the section of asbestos-cement pipes D _j = 200 mm, the intensity of the repair of the section will be equal to µ u _j = 8760 / (485 · 0.001 · D _j -504 · (0.001 · D _j ) ² -27) = 8760 / (485 · 0.001 · 200-504 · (0.001 · 200) ² -27) = 175.76, where µ u _j is the repair intensity of the j-th network section, 1 / year; D _j - the diameter of the pipes of the j-th section, mm;

- complex indicators of maintainability of sections - in cell 14, which is designed to calculate complex indicators of maintainability of sections according to the formula γ u _j (t) = λ u _j (t) / µ _{u j} or according to the formula γ u _j = λ u _j / μ _{uch j} - For example, with λ _uch12-13 (8765) = 0.229 (1 / year) and μ _12-13 = 175.76 γ _uch12-13 (8760) = λ _uch12-13 (8760) / µ _uch12-13 = 0.231 / 175.76 = 0.001314 (see section 12-13 in Fig. 2).

In block 3 for determining the probability indicators of network reliability, the calculation is made:

- the probability of finding the j-th section at time t in a failure state - in cell 16, which is configured to determine the probability of finding the j-th section at time t in a state of failure according to the formula:

.

.

The calculation results are illustrated in the table in FIG. 2, see column 10;

- the probability of finding the network at time t in a partially operational state — in cell 18, which is configured to determine the probability of the network being at time t in a partially operational state by the formula:

.

.

The calculation results are illustrated in the table in FIG. 2, see column 12. In general, from the results presented in figure 2, it is seen.

There is a development option when technological parameters of reliability are additionally determined. Therefore, in block 4 of the definition of technological indicators of the reliability of the drainage network, the calculation is made:

- the volume of emergency discharge of untreated wastewater due to accidents and blockages of the j-th section - in cell 19, which is configured to determine the volume of emergency discharge of untreated wastewater due to accidents and blockages of the j-th section of wastewater networks according to the formula:

.

The calculation results are illustrated in the table in FIG. 2, see column 14;

- the volume of water discharged by the network during the estimated period of operation t when it is in a partially operational state — in cell 21, which is configured to determine the volume of water discharged by the drainage network during the estimated period of operation t when it is in a partially operational state according to the formula :

.

.

The calculation results are illustrated in the table in FIG. 2, see column 15;

- the volume of emergency discharge of untreated wastewater due to accidents and blockages during the estimated period of operation t - in cell 22, which is configured to determine the volume of emergency discharge of untreated wastewater due to accidents and blockages on the drainage network for the estimated period of operation t by the formula :

.

.

The calculation results are illustrated in the table in FIG. 2, see column 16.

Similar results of the calculation, when during an accident and clogging of the jth section, the emergency discharge rate of untreated wastewater is q _jmod , defined in cell 23 of the network simulation, is illustrated in the table in FIG. 3. In this option, when modeling, it is taken into account that some network configurations allow you to change the flow distribution due to accidents and clogging of the j-th section.

In addition to this, in FIG. 4 shows the calculation results when plastic pipes are applied.

As illustrated by the above examples, the use of the proposed "System for determining and providing indicators of reliability and uninterrupted operation of water supply and sanitation networks" in comparison with the prototype allows to expand the scope of its application, since it becomes possible to use it to assess the reliability of the entire network, because it allows one to determine probabilistic reliability indicators in the form of the probability that the entire network is at time t in the working state in the absence of failures of its sections, the probability of the network being in partially-operational states (which are not network failures) when the jth section is found during t in the failure state and etc.

Thus, the proposed system meets the criterion of "industrial applicability".
