Description

Technical Field

[0001] The present invention relates to the technical field of substations, and in particular to a method and system for identifying the type of primary conductive equipment in a substation. Background Art

[0002] Substation SCD (Substation Configuration Description) file is a file format used to describe substation configuration information. It records in detail important information such as substation topology, equipment connections and parameters. With the rapid development of intelligent technology, computer technology and communication technology, substations have achieved intelligent operation and maintenance. SCD configuration files are widely used in the construction of intelligent substations to configure the information of all electrical equipment in the station and the connection relationship between them.

[0003] However, in the current substation construction, the identification of the bay type and the type of primary conductive equipment under the typical wiring mainly depends on the experience of on-site engineers. Based on their electrical expertise, engineers manually write SCD files to configure the information of the primary conductive equipment in the required bay type and the connection relationship between them. However, it is worth noting that the bay type and the specific type of the primary conductive equipment in the bay are not directly recorded in the standard SCD file, which makes the bay type and the type of primary conductive equipment in the configured substation SCD file still unknown. Clear bay types and the types of primary conductive equipment in the bay are crucial for the automatic generation of substation interlocking logic. At present, the interlocking logic configuration of substations is still completed manually by engineers. They need to configure the logic of the separation and combination of the primary conductive equipment in the bay according to their experience, and configure the separation and combination operations of the primary conductive equipment in this bay or other bays that need to be associated when the primary conductive equipment is separated and combined. By configuring the separation and combination operation logic of all primary conductive equipment in the bay, a complete bay interlocking logic file is generated. This has a large workload, low configuration accuracy, and is highly dependent on the professional quality of engineers. Therefore, during the implementation of smart substations, accurately identifying the bay type and primary conductive equipment type, and then associating the opening and closing positions of other primary conductive equipment according to certain logical rules, is a key technical prerequisite for automatically generating bay and station-wide interlocking files.

[0004] The correctness of the bay type and the type of primary conductive equipment within the bay is crucial to the automatic generation of the interlocking logic of the smart substation and the safe operation of the smart substation. In order to achieve the technical requirements of automatic configuration of the interlocking logic, it is urgent to propose a set of accurate and feasible methods for identifying the substation bay type and primary conductive equipment type.

[0101] Step S202: receiving the target substation SCD file;

[0102] Step S204: parsing the SCD file of the target substation to generate a primary conductive equipment model;

[0103] The primary conductive equipment model includes the primary conductive equipment information contained in all bays at all voltage levels of the target substation and the topological connection relationship between bays;

[0104] The primary conductive equipment information includes the physical characteristic information of the primary conductive equipment within the interval at the current voltage level;

[0130] If the physical type characteristics of the primary conductive device include a single-ended line, the interval type corresponding to the primary conductive device is determined to be a line interval; otherwise, the determination is continued based on the physical type characteristics of other primary conductive devices;

[0131] Step 2: According to the topological connection relationship between the bays and the connection relationship between the bays and the busbar, determine the bay type corresponding to the primary conductive device; if the bay type corresponding to the primary conductive device is still not identified, execute step 3;

[0132] Step 2 specifically includes: if the busbar information involved in the endpoint of the primary conductive equipment in the interval is included in at least one other arbitrary interval under the voltage level except the interval itself, it is determined that the interval type corresponding to the primary conductive equipment is a busbar interval;

[0133] If the busbar information involved in the endpoint of the primary conductive equipment in the interval is not included in any other interval under the voltage level except the interval itself, it is determined that the interval type corresponding to the primary conductive equipment is a segmented interval;

[0134] Step S2063: obtaining the connection relationship of the primary conductive equipment, and identifying the bay type corresponding to the primary conductive equipment according to the connection relationship of the primary conductive equipment and the bay type feature rule dictionary; if the bay type corresponding to the primary conductive equipment is still not identified, setting the bay type corresponding to the primary conductive equipment to the default type, and checking whether the bay information in the SCD file of the target substation is configured correctly;

[0135] The bay type feature rule dictionary includes the primary conductive equipment connection relationship under different bays;

[0136] The bay type feature rule dictionary is preset according to the substation operation requirements.

[0137] In step S2063, obtaining the connection relationship of the primary conductive device includes the following steps:

[0138] Step 1: Starting from the target switch, select any endpoint of the target switch as the recursive starting point; the target switch is any switch in the interval;

[0139] Step 2: If the recursive starting point is included in other primary conductive devices, the primary conductive device including the recursive starting point is used as the target primary conductive device, and an end point of the target primary conductive device that is away from the target switch is used as a new recursive starting point;

[0140] Step 3: Recursively judge the end condition. If the target primary conductive device endpoint includes a switch, busbar or grounding wire, stop searching, store the switch, busbar and outgoing line information passed under the above path, and go to step 5.

[0141] Step 4: Repeat steps 2 and 3;

[0143] Step 6: Save the traversal results as the connection relationship of the primary conductive equipment.

[0144] For example: (1) traverse the connected primary conductive devices to obtain the connection relationship of the primary conductive devices; when the connection relationship of the primary conductive devices is switch-bus-switch-bus, match it with the interval type feature rule dictionary to identify the interval type as a string edge interval;

[0145] Under the string side interval, the connection relationship of the primary conductive equipment includes: 1. There is only one switch; 2. Starting from the switch, searching towards both ends, one end is connected to a busbar after being connected through a switch, and the other end is connected to another busbar after being connected through another switch; that is, the connection relationship of the primary conductive equipment is: switch-busbar-switch-busbar;

[0146] (2) traversing the connected primary conductive devices to obtain the connection relationship of the primary conductive devices; when the connection relationship of the primary conductive devices is busbar-switch-switch-busbar, or switch-switch-busbar-busbar, the interval type feature rule dictionary is matched to identify the interval type as a string interval;

[0147] Under the interval in the middle of the string, the connection relationship of the primary conductive equipment includes: 1. There is one and only one switch; 2. Starting from the switch, searching towards both ends, one end (not across the switch) is connected to a bus, and the other end is connected to another bus after being connected through one or two switches; that is, the connection relationship of the primary conductive equipment is: bus-switch-switch-bus, or switch-switch-bus-bus.

[0148] The string side interval and string middle interval are both unique interval types under 3 / 2 wiring.

[0149] According to an optional implementation manner of this embodiment, if it is determined that the interval type is a main transformer high, medium, or low voltage side interval, compare whether the interval name to be identified is in the data structure QMap of the main transformer interval name and interval type, and if so, further determine the interval type to be main transformer high voltage side interval, main transformer medium voltage side interval, or main transformer low voltage side interval;

[0150] Step S208: obtaining the interval type corresponding to the primary conductive device to be identified, and obtaining the corresponding primary conductive device type rule according to the interval type;

[0151] Determine the range of primary conductive equipment types within the interval according to the interval type. In different interval types, the primary conductive equipment types corresponding to the primary conductive equipment may be different;

[0152] For example: the types of primary conductive equipment in a typical interval include busbar side knife switch, switch line side knife switch, IM knife switch, IIM knife switch, PT earth switch, line side earth switch, switch trolley, isolation trolley, etc.

[0153] Step S210: Identify the electrical types of all primary conductive devices in the current interval according to the primary conductive device type rule; including:

[0154] Step S2101: determine whether the primary conductive device information includes the electrical connection relationship of a typical primary conductive device; if it includes, identify the primary conductive device electrical type corresponding to the primary conductive device according to the electrical connection relationship of the typical primary conductive device; if the primary conductive device electrical type corresponding to the primary conductive device is still not identified, execute step S2102;

[0155] The electrical connection relationship of the typical primary conductive equipment includes the connection relationship of the specific primary conductive equipment at a specific interval;

[0156] The electrical connection relationship of typical primary conductive equipment is preset according to the substation operation requirements.

[0157] In this embodiment, the electrical connection relationship of a typical primary conductive device includes:

[0158] Whether the terminals of the primary conductive equipment are directly connected to the busbar;

[0159] Whether the terminals of the primary conductive equipment are connected to the outgoing line;

[0160] Whether the primary conductive equipment terminals are referenced by other voltage level intervals;

[0161] The primary conductive device terminal is connected to the busbar after passing through several switches.

[0162] For example, taking the 220KV voltage level 263 line interval as an example, the primary conductive equipment information includes the primary conductive equipment terminal connection information, and it is judged that the current electrical connection relationship of the primary conductive equipment is a typical primary conductive electrical connection relationship. The earth switch connected to the primary conductive equipment terminal and the outgoing line is the line side earth switch, the knife switch connected to the primary conductive equipment terminal and the outgoing line is the switch line side knife switch, the knife switch connected to the primary conductive equipment terminal and bus No. I is the I bus side knife switch, and the knife switch connected to the primary conductive equipment terminal and bus No. II is the II bus side knife switch.

[0163] Step S2102: Acquire the electrical connection relationship of the primary conductive device, match the electrical connection relationship of the primary conductive device with the primary conductive device type feature rule dictionary, and identify the primary conductive device electrical type corresponding to the primary conductive device;

[0164] The primary conductive equipment type characteristic rule dictionary includes the electrical connection relationship of different primary conductive equipment;

[0165] The primary conductive equipment type characteristic rule dictionary is preset according to the substation operation requirements.

[0166] In this implementation, the primary conductive device type feature rule dictionary includes:

[0167] I bus side switch: the switch whose endpoint is connected to bus No. I;

[0168] II busbar side switch: the switch whose endpoint is connected to busbar II;

[0169] Switch line side knife switch: the knife switch connected to the outgoing line side;

[0170] Switch bus side grounding knife: It is a grounding knife connected to the busbar after passing through a knife switch without switching;

[0171] Switch CT side grounding knife: a grounding knife connected to the busbar after passing through a switch and a knife switch;

[0172] Line side grounding knife: the grounding knife connected to the outgoing line side;

[0173] Line switch: switch within the line bay type;

[0174] Wherein, in step S2102, obtaining the electrical connection relationship of the primary conductive device includes:

[0175] Step 1: Starting from the current primary conductive device, select any endpoint of the current primary conductive device as the recursive starting point;

[0176] Step 2: When the recursive starting point is included in other primary conductive devices, the primary conductive device including the recursive starting point is used as the target primary conductive device, and an end point of the target primary conductive device that deviates from the recursive starting point is used as a new recursive starting point;

[0177] Step 3: Recursively judge the end condition. If the current primary conductive device endpoint includes a switch, busbar or grounding wire, stop searching, store the switch, busbar and outgoing line information passed under the above path, and go to step 5.

[0178] Step 4: Repeat steps 2 and 3;

[0179] Step 5: When the traversal of the endpoints on one side of the current conductive device is completed, an endpoint that has not been traversed by the current conductive device is used as the recursive starting point, and the recursive search continues, and steps 2, 3, and 4 are repeated until the traversal of the endpoints on both sides of the current conductive device is completed;

[0180] Step 6: Save the traversal results as the electrical connection relationship of the primary conductive equipment.

[0181] For example: Taking 220KV voltage level 263 line interval as an example,

[0182] (1) The current bay type is a line bay, and the electrical connection relationship of the primary conductive equipment is obtained as switch-bus or bus-switch; the primary conductive equipment type feature rule dictionary is queried, and according to the record in the primary conductive equipment type feature rule dictionary: in the line bay, switch-bus or bus-switch corresponds to the switch bus side earthing knife; it is determined that the electrical type of the primary conductive equipment corresponding to the next primary conductive equipment of the current bay type is the switch bus side earthing knife;

[0183] (2) The current interval type is a line interval, and the electrical connection relationship of the primary conductive equipment is obtained as switch-outlet or outlet-switch. The primary conductive equipment type feature rule dictionary is queried, and according to the records in the primary conductive equipment type feature rule dictionary: within the line interval, switch-outlet or outlet-switch corresponds to the switch CT side earthing knife; it is determined that the primary conductive equipment electrical type corresponding to the next primary conductive equipment of the current interval type is the switch CT side earthing knife.

[0184] The present invention generates a primary conductive device model by reading and parsing the target SCD file, and the primary conductive device model identifies the interval type by combining the electrical topology connection relationship and the interval type characteristic rule dictionary analysis, and then identifies the electrical type of the primary conductive device according to the interval type, the primary conductive device model, the electrical topology interval relationship of the primary device in the interval, and the primary conductive device type characteristic rule dictionary analysis.
