Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
In addition, all directions or positional relationships mentioned in the embodiments of the present invention are positional relationships based on the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not imply or imply that the referred device or element must have a specific orientation, and are not to be construed as limiting the present invention.
One embodiment of the invention provides an arrangement control method of an intelligent draw-out type low-voltage switch cabinet system. The arrangement control method only aims at the drawer cabinet, and does not arrange the incoming line cabinet or the bus connection cabinet and the like. The draw-out type low-voltage switch cabinet system is hereinafter referred to as a switch cabinet. The method comprises the following specific steps:
s1: acquiring low-voltage load information and the number of bus sections participating in the distribution of the switch cabinet;
s2: determining the size of the drawer corresponding to each load according to the load information;
s3: determining the number and size of the arrangement drawers in each bus-section according to the number of the bus-sections and the size of the arrangement drawers;
s4: identifying the area of each switch cabinet, which is participated in the arrangement of the arrangement drawers, and sequentially arranging all the arrangement drawers to the area of the switch cabinet, which is participated in the arrangement of the arrangement drawers, according to the number and the size of the arrangement drawers;
s5: and arranging the arrangement drawers in the area of each switch cabinet participating in arrangement of the arrangement drawers according to the sizes of the arrangement drawers to obtain a panel arrangement diagram comprising the load information.
In this embodiment, there are one or more bus bar sections to be arranged in the switch cabinet, each section includes a multi-surface switch cabinet, each surface of the switch cabinet can accommodate a plurality of drawers, and each drawer corresponds to a power supply load.
In step S1, the number of desired bus-sections is determined, and may be set as one or two sections according to the actual conditions of the project; and acquiring information of all low-voltage loads from a power supply load table of the project, wherein the information comprises load power, voltage level, calculated current, loop type (feeder loop or motor loop), control mode and the like, and finally selecting loads to be arranged from all the loads, wherein the selection principle of the loads participating in the switch cabinet arrangement is determined according to the specific situation of the project. The step of S1 includes: acquiring all load information and load acquisition principles, wherein the load acquisition principles comprise screening of load names; and screening the load information participating in the configuration according to the load acquisition principle. Here, the screening of the loads participating in the arrangement according to the selection rule includes screening or filtering the loads with certain keywords in the load names. For example, an illumination maintenance section is arranged in the substation, only illumination and maintenance loads are selected in the arrangement, namely loads with illumination and maintenance characters in all names are selected, and other loads do not participate in the arrangement.
In S2, the size of the drawer required to participate in the load arrangement needs to be calculated. The size of the drawer corresponding to each load is selected according to the type, load capacity or calculation current of the loop, and different items have different selection principles and can be customized. The dimensions of the drawer are indicated by the modulus D, in this embodiment 1D equal to 200mm high, the total height of the switchgear cabinet being generally 2200mm or 2000 mm. The D number represents the capacity of the switch cabinet occupied by each drawer on the cabinet surface. In this embodiment, the total capacity of a single switch cabinet is 9D, and common drawers generally have 0.5D, 1D, 2D, 3D and the like.
In S3, the load is segmented, and a group of devices that need to be started and stopped in the project are divided into different segments. For example, a group of fire-fighting water pumps with equipment position numbers of P28501A/B, which are one on and one off, needs to distribute the two load inlet wires into two different sections so as to improve the power supply reliability; in addition, a single primary load or a single secondary load which needs to be powered by double power supplies needs to be arranged in a segmented mode, and the requirement of the grade is met. And as for the rest general loads, the loads are distributed into all the sections as evenly as possible, so that the power supply balance is met. The corresponding drawer size is selected according to the type, load capacity or calculation current of the actual loop, and the number of switch cabinets and the total number D of the drawers in each section are counted after the section is completed, so that the drawer can be used in the subsequent step S5. In said step S3, a specific load is first split and then the remaining load is split equally into each of said bus-sections. For example, the remaining generic load of drawers would have 103 drawers at 0.5D, 81 drawers at 1D, 45 drawers at 2D and 10 drawers at 3D, if distributed into two bus-sections, the result would be A-sections: 52 0.5D, 41 1D, 23 2D and 5 3D, B segments: 51 0.5D, 40 1D, 22 2D and 5 3D.
In S3, load screening is required, a group of one-on-one-standby circulating water pumps are divided into two different bus sections, for example, a group of one-on-one-standby circulating water pumps with equipment numbers P28501A and P28501B, and two loads, namely P28501A and P28501B, are required to be arranged into different bus sections, so as to improve power supply reliability; in addition, two power supplies of the dual power supply load also need to be distributed in different bus sections to meet the requirement of the power load grade. The size of the corresponding drawer is selected according to the type of the actual load, the capacity of the load or the calculation current, and the total sum of the number of all the drawers and the total D number are counted.
In the step S3, determining a total of the load capacities according to the size and the number of each of the arranged drawers, wherein the load capacity is a total of sizes of all the drawers; said alignment drawers are then equally divided into each of said bus-sections by the sum of said load capacities. That is, the load needs to be divided equally among the different bus-sections. For example, if there are a total of 103 drawers of size 0.5D, it is necessary to divide 52 of the 103 drawers into a first bus-section and the remaining 51 drawers into a second bus-section. If the drawers are of different sizes, the total number D of the drawers is divided so that the total number D of each bus-section is equal.
The method also includes the following steps in S3: determining the number and size of the spare drawers according to the load information; determining the arrangement area of the spare drawers according to the number and the size of the spare drawers; inserting the spare drawer into an arrangement area of the spare drawer in the switch cabinet. In this embodiment, all the drawers are classified and counted, the capacity of the spare drawer required by the drawer is calculated according to a certain proportion, and the spare drawer is inserted into the switch cabinet arranged in S4. And carrying out classified statistics on all the drawers according to the following classification basis: the feeder circuit is classified according to the magnitude of the thermal tripping current of the circuit breaker, and the motor circuit is classified according to the magnitude of power and a control mode; counting various drawers, and calculating the number of the required standby drawers according to the proportion. For example, if the spare drawers are calculated according to the proportion of 20%, 1.8 spare drawers with the capacity of 11kW and the control modes of LO and LP are needed; and calculating the total capacity of the spare drawers, and judging whether the residual capacity in the switch cabinet arranged in the S4 can accommodate all the spare drawers. If the capacity is insufficient, a new cabinet surface needs to be added for capacity expansion. For example, the section A is provided with 20 switch cabinets, each face is reserved with 2D capacity, and then the total spare capacity is 40D. However, assuming that the total capacity of the required spare drawer calculated according to the proportion of 20% is 50D, two new switch cabinets are required to be added to the section A; evenly segmenting the spare drawers; inserting the segmented spare drawer into the spare area in the arranged switch cabinet in the S4; the remaining switch cabinet area is filled up, for example, after two new cabinets are added in the above example, the last cabinet is only 1D of capacity, and 8D of unfilled cabinet remains, and the cabinet is filled up by randomly filling any drawer.
At S4, the switch cabinet includes a first switch cabinet and a second switch cabinet, the step S4 includes: s41: acquiring the load capacity N of the first switch cabinet, and calculating the sum M of the sizes of all the arranged drawers in the first switch cabinet; s42: and when M is larger than N, dividing part of drawers in the first switch cabinet into the second switch cabinet, so that M is smaller than or equal to N. For example, a first switch cabinet may include a capacity of 9D, where 7D is the capacity of the row of drawers and the remaining 2D is the capacity of the row of spare drawers, and then the second switch cabinet may be arranged after the first switch cabinet is filled to capacity with 7D. Here, assuming that the total D number of the switch cabinets already arranged in the first switch cabinet is t, the sizes of the arranged drawers include 0.5D and 1D, the sizes of the drawers are 0.5D, 1D, and 1D in this order, the arrangement of the first row of drawers in the first switch cabinet is performed first, and at this time, t =0.5< = 7; then, the arrangement of the second row is performed, at which time t =0.5+0.5< = 7; the arrangement of the drawers in each row is carried out in sequence, and when the arrangement of the drawers in the 12 th row is carried out, the total D number of the arrangement of the switch cabinets is as follows: t =0.5+0.5+0.5+0.5+0.5+ 1+1=7.5D >7D, the total D number of switch cabinet arrangements that have been made at this time exceeds the arrangement capacity of the first switch cabinet, and therefore the last switch cabinet needs to be arranged in the second switch cabinet, then the total capacity of the drawers in the first switch cabinet is: t =0.5+0.5+0.5+0.5+0.5+0.5+0.5+0.5+0.5+1+1=6.5D, and the other drawers with the size of 0.5D are arranged in the first switch cabinet, so that the arrangement of the first cabinet is completed. And sequentially, until the sizes of the drawers corresponding to the loads in all the switch cabinets are determined. And S4, when the arrangement drawers in each switch cabinet are arranged according to the sizes of the arrangement drawers, arranging all the arrangement drawers in the order from top to bottom and from small to large.
In S4, the segmented loads are arranged in segments, and the drawers are sequentially arranged in each segment of the switch cabinet, and a certain capacity is reserved for arranging spare drawers in a single switch cabinet. The step of S4 includes: s41: determining the size of the reserved capacity required by a single switch cabinet of the project; s42: and sequentially arranging the drawers in the section into the switch cabinet, if the drawer exceeds the capacity of a single cabinet by 9D, selecting a smaller drawer backwards for filling until the single-side switch cabinet is filled, and continuously arranging the next cabinet. For example, if each switchgear is provisioned to reserve 2D of spare capacity, then there is a remaining 7D capacity for normal alignment. Assuming that the sizes of the first 8 drawers to be arranged are 3D, 2D, 0.5D, 1D and 2D … … in sequence, when the drawer is arranged to the third drawer, the capacity of the first-side switch cabinet is found to overflow, namely, the capacity exceeds 7D, and then the smaller drawers are continuously selected backwards to be filled until the first-side cabinet is fully arranged at 7D. The skipped drawers are automatically arranged in the next cabinet. The final layout result is therefore: the first surface cabinet is 3D, 0.5D and 0.5D, and the second surface cabinet is 2D, 1D and 2D. The subsequent drawer arrangement method is the same as the above until the arrangement of all the drawers in the section is completed, and another section is arranged by the same method. In S4, the drawers are sequentially arranged into the switch cabinet, and the drawers are arranged on one side and then on the other side until all the drawers are arranged.
In this embodiment, before the step S4, the method further includes: acquiring the same number of loads; when the number of the same loads is greater than or equal to 2, the same loads are respectively arranged in different switch cabinets. For example, the loads include first loads, the number of the first loads is 2, and in this case, the first loads need to be arranged in different switch cabinets respectively.
Here, after the step of S5, all the arrangement drawers are numbered in turn. And sequentially numbering all the arranged drawers, and reversely filling the serial numbers of the arranged drawers of the loads into a cable list.
In step S5, the step of obtaining a drawer panel of a switch cabinet including the load information further includes: determining the position of a self-defined switch cabinet drawer according to the switch cabinet drawer panel diagram; and adjusting the positions of the arrangement drawers according to the positions of the self-defined switch cabinet drawers. That is, when the arrangement drawers are arranged in the switch cabinet, since the spare drawers are inserted, the positions of the plurality of drawers in one cabinet need to be changed manually, in this embodiment, the spare drawers are arranged on the drawers, and the arrangement drawers are arranged downward in the order from small to large. Here, the position of the arrangement drawers is adjusted in the single-sided switch cabinet as required to achieve a desired arrangement layout scheme. When the switch cabinet drawer panel images are arranged in an initial stage, the position of the arranged drawers is adjusted in a user-defined mode according to actual needs, and the position of the drawer of the user-defined switch cabinet is determined. The custom adjustment varies according to actual needs, for example, arranging the same-size arranged drawers to the same row of areas in the switch cabinet. For example: the spare drawers are arranged to the same row of zones in the switchgear cabinet. The complexity, variable factors and the like in the actual design process are considered, the artificial participation in the monitoring and feedback process is increased to the maximum extent on the premise of reducing the artificial participation in the operation process to the maximum extent, and the method is more flexibly suitable for various projects.
The method comprises the steps of predetermining the number of bus sections and information of loads participating in arrangement, then determining the sizes of drawers corresponding to the loads participating in arrangement, further determining the sizes and the number of the drawers in each bus section, arranging the drawers in a switch cabinet in each bus section, and finally arranging the arranged drawers in sequence and outputting corresponding composite information and a switch cabinet drawer panel diagram containing the load information. And converting the plane position relationship into an abstract mathematical logic relationship, and finally regenerating a plane position diagram.
In S5, the final position of the aligned drawer is adjusted, and the drawer number corresponding to each load is back-filled in the cable list. The step of S5 includes: according to project regulations or custom of designers, the position of the drawers in each switch cabinet is adjusted, for example, the expected sequence of the drawers in the switch cabinet is as follows: standby is carried out from small to large on the upper part; generating a tray layout according to the final drawer position; generating the model and parameters of the circuit breaker, the contactor, the motor protector and the like required by each drawer according to the final drawer position and factory databases such as a switch cabinet, a circuit breaker and the like, and integrating all information into a primary system diagram; the number of each drawer is back filled into the cable book. For example, if a 100AL light box in the cable book has a load located at the corresponding drawer position in the substation at bus bar a, 6 th drawer on the 8 th side switch cabinet, then the load number 8AA-6 is back-filled to the cable book at the beginning of the cable corresponding to the load; and generating information of all cables contained in each switch cabinet into a wiring table.
The method comprises the steps of predetermining the number of bus sections and information of loads participating in arrangement, then determining the sizes of drawers corresponding to the loads participating in arrangement, further determining the sizes and the number of the drawers in each bus section, arranging the drawers in a switch cabinet in each bus section, and finally arranging the arranged drawers in sequence and outputting corresponding composite information and a switch cabinet drawer panel diagram containing the load information. And converting the plane position relationship into an abstract mathematical logic relationship, and finally regenerating a plane position diagram. And finally, outputting a panel layout diagram which can visually represent the panel layout of the switch cabinet and a primary system diagram which integrates all switch cabinet information by taking a load meter or a cable meter book supplied by a substation as an input condition. The large switch cabinet system is converted into abstract mathematical logic and then into an image floor plan.
The embodiment of the invention provides an arrangement control device of an intelligent draw-out type low-voltage switch cabinet system, which comprises:
the system comprises an acquisition module, a distribution module and a control module, wherein the acquisition module is used for acquiring load information participating in the distribution of the switch cabinets and the number of bus sections, and each bus section comprises at least one switch cabinet;
the conversion module is used for determining the size of the arrangement drawer corresponding to each load according to the load information;
a calculation module for determining the number and size of the alignment drawers in each bus-section according to the number of bus-sections and the size of the alignment drawers;
the dividing module is used for identifying the area participating in arrangement of the arrangement drawers in each switch cabinet and sequentially arranging all the arrangement drawers to the area participating in arrangement of the arrangement drawers in the switch cabinet according to the number and the size of the arrangement drawers;
and the arrangement module is used for arranging the arrangement drawers in the area of each switch cabinet participating in arrangement of the arrangement drawers according to the sizes of the arrangement drawers to obtain a switch cabinet drawer panel diagram including the load information.
The arrangement of a draw-out type low-voltage switch cabinet system relates to a large number of low-voltage loads and low-voltage cables, and requires a designer to calculate, arrange and arrange the loads within a limited time; based on the particularity of the arrangement of the draw-out type low-voltage switch cabinet system, namely the change of a single drawer affects the arrangement of the whole system (similar to the situation that when building blocks are built, one building block is drawn out, so that the whole system collapses completely), and the change of load information frequently occurring in the actual design process is added, so that a great deal of labor and a great amount of repetitive work are involved. The process is complex in steps and complex in calculation, and needs designers to plan comprehensively and change flexibly; the size of the cable is as large as the disc surface layout of the whole switch cabinet system, and the size of the cable is as small as each drawer, so that the designer can consider the cable. After the arrangement is completed, designers still need to manually fill information into a primary system diagram, and manually count the cable information contained in each switch cabinet. The whole system is arranged completely, the time is short, three days and five days are used, the time is long, and a week is needed again if the load information changes in the midway. In general, the process is time-consuming and labor-consuming, the error rate is very high, and finally the design quality is not high and the design progress is delayed. Now, with the gradual expansion of the project scale, the number of loads included in the substation in the project is increased by times, and if the original old design and arrangement method is still adopted, the whole design progress is greatly slowed down. Therefore, the design mode of the current low efficiency is changed, and a brand new device for automatically arranging and controlling the machines is created, which needs to be solved urgently.
The arrangement device of the intelligent draw-out type low-voltage switch cabinet system only needs about 10 minutes from input conditions to output results, the design time is shortened by more than 99 percent, the efficiency is improved by more than 100 times, the arrangement accuracy of the device is 100 percent, no error possibility exists, and no matter how large the load quantity is, the efficiency cannot be changed as long as the system capacity limit is met.
