Description

Technical Field

[0001] This invention relates to the field of power configuration technology, and in particular to a method and apparatus for configuration-free analog channels of an intelligent fault recording device. Background Technology

[0002] With the development of high-reliability substations, in order to improve configuration efficiency and reduce the probability of manual configuration errors, configuration tools that do not rely on Substation Configuration Description (SCD) have been developed. Intelligent Electronic Devices (IEDs) can autonomously construct virtual loops based on standardized datasets, which is referred to as the configuration-free system.

[0003] Fault recording devices play a crucial role in ensuring the safe operation of power systems. When a fault occurs in the power grid, the installed fault recording device can record the waveforms and RMS values ​​of the three-phase current and zero-sequence current on the line, as well as the waveforms and RMS values ​​of the three-phase voltage and zero-sequence voltage on the bus, throughout the entire fault process. It generates a fault analysis report, indicating the fault type and allowing users to view the amplitude and phase of current and voltage, the operating time of local protection, the transmission and shutdown times of high-frequency protection transceivers on both sides of the line, and the opening and closing times of circuit breakers. When automatic reclosing devices are installed on both sides of the line, the entire process of automatic reclosing operations on both sides can also be observed. Therefore, to adapt to the development of configuration-free systems, intelligent fault recording devices also need to develop efficient and accurate automatic configuration technology without SCD files. The development of configuration-free technology is of great significance for improving operation and maintenance efficiency and alleviating the shortage of power system operation and maintenance personnel. However, current research on configuration-free intelligent fault recording devices is limited, and their application faces significant challenges.

[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0054] This invention provides a configuration-free method for the analog channel of an intelligent fault recording device. Figure 1 This is a flowchart of the configuration-free method for the analog channel of the intelligent fault recording device provided by the present invention, as shown below. Figure 1 As shown, the method includes the following steps:

[0055] Step S101: Receive and parse the GenericObject Oriented Substation Event (GOOSE) and Sampled Values ​​(SV) control blocks of the acquisition execution unit to determine the local interval without configuration parameters;

[0056] Step S102: Divide the components into primary components according to the parsed local interval;

[0057] Step S103: Based on the type of acquisition and execution unit, perform the association processing between the analog signal channel and the primary element.

[0058] In this method, firstly, the GOOSE and SV control blocks of the acquisition execution unit are received, and the local intervals of the configuration-free parameters are determined from each SV control block. Then, the primary components are divided according to the parsed local intervals. Finally, the analog channels and primary components are associated according to the type of the acquisition execution unit. In the above process, the message is analyzed and processed with the acquisition execution unit as the center. The primary topology (primary components and their associations) and analog channel intelligent identification can be realized accurately and without error based on the dynamic parsing of real-time messages. This achieves the goal of configuration-free analog channels in intelligent fault recording devices, avoiding the disadvantages of other methods that require prior knowledge of the primary wiring type or reliance on the System Configuration Description (SCD) file. In particular, it is still applicable to special wiring types such as 3 / 2 (4 / 3) wiring, line transformer group wiring, and expanded internal bridge, achieving a "plug and play" effect. This solves the problem of the difficulty in applying configuration-free schemes to intelligent fault recording devices in existing related technologies.

[0059] In some embodiments, step S101, receiving and parsing the GOOSE and SV control blocks of the acquisition execution unit to determine the local interval without configuration parameters, includes: parsing all received GOOSE and SV control blocks of the acquisition execution unit; parsing the local interval without configuration parameters in the SV control block, and numbering the parsed local intervals according to the interval type that needs to be recorded; the interval type includes bus, main transformer, line, circuit breaker, bus tie, section and high-resistance body.

[0060] For example, the GOOSE and SV control blocks of all received acquisition execution units are parsed; the local intervals of the configuration-free parameters within each SV control block are parsed. The parsed local intervals are numbered according to the interval type such as bus, main transformer, line, circuit breaker, bus tie, section, and high-resistance body that need to be recorded.

[0061] In some embodiments, step S102, dividing the primary components according to the parsed local bay, includes: dividing the parsed local bays into corresponding bus group components, main transformer components, line components and circuit breaker components according to the bay type and number.

[0062] Further, after dividing the bus group components, the process includes: reading the virtual terminal connection parameters of the PT acquisition and execution unit (only acquiring voltage) corresponding to the bus group components; the virtual terminal connection parameters include 1-segment / 2-segment bus tie intervals and 2-segment / 3-segment bus tie intervals; constructing the corresponding number of bus components according to the virtual terminal connection parameters and numbering them.

[0063] Specifically, based on the virtual terminal connection parameters, a corresponding number of busbar components are constructed and numbered, including: if the bus tie interval between segments 1 and 2 (i.e., between segments 1 and 2) is not 0 and the bus tie interval between segments 2 and 3 is 0, then 2 busbar components are constructed and numbered sequentially; if the bus tie interval between segments 1 and 2 is not 0 and the bus tie interval between segments 2 and 3 is not 0, then 3 busbar components are constructed and numbered sequentially; if the bus tie interval between segments 1 and 2 is 0 and the bus tie interval between segments 2 and 3 is 0, then 1 busbar component is constructed and numbered sequentially.

[0064] For example, the virtual terminal connection parameters of the PT (Potential Transformer) acquisition and execution unit corresponding to the bus group are read: 1 / 2 segment bus tie interval, 2 / 3 segment bus tie interval. If the 1 / 2 segment bus tie interval is not 0 and the 2 / 3 segment bus tie interval is 0, 2 bus elements are established and numbered in sequence. If the 1 / 2 segment bus tie interval is not 0 and the 2 / 3 segment bus tie interval is not 0, 3 bus elements are established and numbered in sequence. If the 1 / 2 segment bus tie interval is 0 and the 2 / 3 segment bus tie interval is 0, 1 bus element is established and numbered in sequence. The numbers of all bus elements are sequentially incremented and do not repeat.

[0065] Based on the above embodiments, processing is performed according to the type of acquisition execution unit to associate analog channels with primary components. The process includes: determining the type of acquisition execution unit based on the received Application Identification (APPID). For different types of acquisition execution units, processing is performed according to the different types of virtual terminal connection parameters and local intervals.

[0066] Depending on the type of the acquisition execution unit, when associating analog channels with primary components, for acquisition execution type I units: if the local bay is a line, the current of the acquisition execution unit is associated with the corresponding numbered line component, and the line bay is associated with the corresponding bus component; the line voltage is automatically associated with the corresponding group voltage of the bus acquisition execution unit. If the local bay is a main transformer, the current of the acquisition execution unit is associated with the corresponding numbered main transformer branch, and the main transformer branch is associated with the corresponding bus component; the main transformer branch voltage is automatically associated with the corresponding group voltage of the bus acquisition execution unit. If the local bay is a circuit breaker, the current and voltage of the acquisition execution unit are associated with the corresponding circuit breaker component and the corresponding numbered line component. If the local bay is a bus tie, the bus tie bay is associated with the bus component divided by its bus group, and the current of the corresponding group of the acquisition execution unit is automatically selected. If the local bay is a segment, the segment bay is associated with the bus component divided by its corresponding bus group, and the current of the corresponding group of the acquisition execution unit is automatically selected.

[0067] For example, for a type I acquisition and execution unit, the association processing procedure is as follows:

If PT2 is selected as 1, the bus tie interval will be automatically associated with the second bus element divided by the corresponding bus group (for bus differential current analysis).

If the local bay is a line and the data acquisition and execution unit is not a PT data acquisition and execution unit, the current of the data acquisition and execution unit is associated with the corresponding numbered line element, and the line bay is associated with the bus element divided by the corresponding bus group. The line voltage is automatically associated with the voltage of the corresponding group of the bus acquisition and execution unit. If the local bay is a line and the data acquisition and execution unit belongs to a PT data acquisition and execution unit, the voltage of the corresponding group of the data acquisition and execution unit is automatically associated with the corresponding line element. If the local bay is a main transformer and the data acquisition and execution unit is not a PT data acquisition and execution unit, the current of the data acquisition and execution unit is associated with the corresponding numbered main transformer branch, and the main transformer branch is associated with the bus element divided by the corresponding bus group. The voltage of the main transformer branch is automatically associated with the voltage of the corresponding group of the bus acquisition and execution unit. If the local bay is a main transformer and the data acquisition and execution unit is a PT data acquisition and execution unit, the voltage of the corresponding group of the data acquisition and execution unit is automatically associated with the corresponding main transformer branch. If the local bay is a circuit breaker, the corresponding group of current and voltage of the acquisition and execution unit will be associated with the corresponding circuit breaker element and the corresponding numbered line element; if the local bay is a bus tie, the bus tie bay will be associated with the bus element divided by the corresponding bus group, and the corresponding group of current of the acquisition and execution unit will be automatically selected; if the local bay is a segment, the segment bay will be associated with the bus element divided by the corresponding bus group, and the corresponding group of current of the acquisition and execution unit will be automatically selected.

[0074] For example, for the Type II acquisition and execution unit, the association processing procedure is as follows:

[0075] 1. If the local interval is a line and the acquisition execution unit is not a PT acquisition execution unit, then the first group of current of the acquisition execution unit will be automatically associated with the corresponding numbered line element; the virtual terminal connection parameter "Connect bus group" will be read to determine the bus group to which it belongs, and the voltage will be selected from the acquisition unit of that bus group.

If PT2 is selected as 1, the main transformer branch is automatically associated with the second bus element in the corresponding bus group and the third group of voltages in the automatic bus acquisition and execution unit. If the local interval is the main transformer and the acquisition and execution unit is a PT acquisition and execution unit under condition 2, the virtual terminal connection parameter "PT type" (to distinguish whether the main transformer is a high-voltage branch or a medium-voltage branch) is read. Then, the first group of voltages in the acquisition and execution unit is automatically associated with the corresponding virtual bus element, and the main transformer branch is automatically associated with the virtual bus element.

Then, the virtual terminal connection parameters "Connecting Side 1 Circuit Breaker Bay", "Connecting Side 2 Circuit Breaker Bay", "Connecting Side 1 Bus Group", "Connecting Side 1 Bus Group", "Connecting Side 1 Line Bay", "Connecting Side 1 Main Transformer Bay", "Side 1 Main Transformer Branch", "Connecting Side 2 Bus Group", "Connecting Side 2 Bus Group", "Connecting Side 2 Line Bay", "Connecting Side 2 Main Transformer Bay", and "Side 2 Main Transformer Branch" are parsed. The voltage of the circuit breaker element is automatically associated according to the following conditions.

[0083] 1.1 When “Connection Side 1 Busbar Group” is not “0” and “Connection Side 2 Busbar Group” is “0”, determine whether Side 2 is a line interval or a main transformer interval, and then automatically associate the circuit breaker element with the corresponding line or the first group of voltage acquisition and execution unit of the main transformer PT.

[0084] 1.2 When “Connection Side 2 Busbar Group” is not “0” and “Connection Side 1 Busbar Group” is “0”, determine whether Side 1 is a line interval or a main transformer interval, and then automatically associate the circuit breaker element with the corresponding line or the first group of voltage of the main transformer PT acquisition and execution unit.

[0085] 1.3 When both “Connecting Side 1 Busbar Group” and “Connecting Side 2 Busbar Group” are “0”, determine whether Side 1 interval is a line interval or a main transformer interval (for Side 1 line and Side 1 main transformer, take the one that is not 0), and then automatically associate the circuit breaker element with the corresponding line or the first group of voltages of the main transformer PT acquisition and execution unit.

[0086] Establish the interval relationship between edge 1 and edge 2 associated with all circuit breaker acquisition and execution units, and automatically associate the currents of other components connected to the circuit breaker components according to the following conditions:

[0087] 1.4 When “Connecting Side 1 Busbar Group” is non-zero, “Connecting Side 2 Busbar Group” is zero, “Connecting Side 2 Line Bay” or “Connecting Side 2 Main Transformer Bay” is non-zero, the first group of currents of this acquisition and execution unit will be associated with the corresponding Side 2 line element or the corresponding branch of Side 2 main transformer;

[0088] 1.5 When “Connecting Side 1 Line Spacing” or “Connecting Side 1 Main Transformer Spacing” is non-zero, and “Connecting Side 2 Line Spacing” or “Connecting Side 2 Main Transformer Spacing” is non-zero, the Side 2 line element or the branch corresponding to the Side 2 main transformer corresponding to the first group of current association of this acquisition and execution unit, and the Side 1 line element or the branch corresponding to the Side 1 main transformer corresponding to the second group of current association of this acquisition and execution unit are associated.

[0090] 2. If the local interval is a high-resistance body sampling type acquisition execution unit, then the first group current and the second group current of the acquisition execution unit will be automatically selected (for waveform recording only).

[0091] For bus acquisition and execution units: If the local interval is a bus group, then the voltage of the acquisition and execution unit is sequentially associated with the bus elements of the corresponding bus group.

[0092] For example, the association processing procedure for the bus acquisition and execution unit is as follows:

[0093] If the local interval is a bus group, the voltage of the acquisition and execution unit is sequentially associated with the bus elements of the corresponding bus group. If there is only one bus element, the first group of voltages is associated; if there are two bus elements, the first group of voltages and the second group of voltages are associated sequentially; if there are three bus elements, the first group of voltages, the second group of voltages, and the third group of voltages are associated sequentially.

[0094] This invention also discloses a configuration-free device for the analog channel of an intelligent fault recording device. The configuration-free device for the analog channel of an intelligent fault recording device provided by this invention will be described below. The configuration-free device for the analog channel of an intelligent fault recording device described below and the configuration-free method for the analog channel of an intelligent fault recording device described above can be referred to in correspondence with each other. Figure 2 This is a structural block diagram of the analog channel configuration-free device of the intelligent fault recording device provided by the present invention, as shown in the figure. Figure 2 As shown, the device includes:

[0095] The parsing module 201 is used to receive and parse the GOOSE and SV control blocks of the acquisition execution unit to determine the local interval without configuration parameters;

[0096] The partitioning module 202 is used to partition the components into primary components based on the parsed local intervals;

[0097] The processing module 203 is used to perform association processing between analog signal channels and primary components according to the type of acquisition and execution unit.

[0098] When this device is in use, firstly, the parsing module 201 receives the GOOSE and SV control blocks from the acquisition execution unit and parses and determines the local intervals with configuration-free parameters from each SV control block. Then, the partitioning module 202 partitions the primary components according to the parsed local intervals. Finally, the processing module 203 performs the association processing between the analog channels and the primary components according to the type of the acquisition execution unit. In the above process, the message is analyzed and processed with the acquisition execution unit as the center. It can accurately and errorlessly realize the primary topology (primary components and their associations) and intelligent identification of analog channels based on the dynamic parsing of real-time messages. This achieves the goal of configuration-free analog channels in intelligent fault recording devices, avoiding the disadvantages of other methods that require prior knowledge of the primary wiring type or reliance on SCD files. In particular, it is still applicable to special wiring types such as 3 / 2 (4 / 3) wiring, line transformer group wiring, and expanded internal bridge, achieving a "plug and play" effect. This solves the problem of the difficulty in applying configuration-free schemes to intelligent fault recording devices in existing related technologies.
