Description

Technical Field

[0001] The invention relates to a voltage and current loop patrol configuration method based on an ICD model, and belongs to the technical field of patrol of secondary equipment of intelligent relay protection in power systems. Background Art

[0002] Due to rapid economic and technological development, smart substations are rapidly gaining popularity, and intelligent relay protection systems are being put into operation on a large scale. However, due to the limitations of technology in the early stages of smart substation design, the design of equipment models was not fully considered, and there was a lack of modeling for the equipment's voltage and current loop patrol function. At the same time, due to the increasing requirements for grid operation safety and stability, the requirements for relay protection equipment's voltage and current loop patrol function are also increasing. Automatic voltage and current loop patrol functions are needed to meet the needs of safe and reliable grid operation. The application of voltage and current loop patrol functions is expected to enable rapid configuration, shortening commissioning time and power outage duration. However, due to the lack of relevant models for voltage and current loop patrol functions, the configuration process requires a large number of manual configuration operations. The entire configuration process is cumbersome and error-prone, and each configuration needs to be tested to verify its correctness. This results in low overall efficiency, long power outages, and an inability to ensure safe and stable grid operation.

[0003] The intelligent relay protection capability description file (ICD) describes the functions and engineering capabilities of a specific IED. It includes model self-description information, device manufacturer name, device type, version number, version modification information, and a clear description of the modification time and modification version number. IEDs of the same model have the same ICD template file.

[0004] As a capability description file of intelligent relay protection, ICD file is an important basis for obtaining relay protection information. In the debugging, acceptance, maintenance, overhaul and renovation and expansion of the intelligent substation, the ICD file is the most basic model file. The SCD file integrated by ICD runs through the entire life cycle of the intelligent substation. In order to standardize the content of the ICD file, the State Grid Corporation of China issued and implemented the "Q / GDW_1396-2012 IEC_61850 Engineering Relay Protection Application Model" and the Southern Power Grid issued and implemented the "Q_CSG1203065-2020_Substation IEC61850 Engineering General Application Model", which clearly specified the logical device (LD), logical node (LN), prefix (prefix), instance number (inst), data (DO), functional constraint (FC), and data attribute (DA) of the ICD model. Based on the above reasons, the present invention proposes a voltage and current loop patrol configuration method based on the ICD model. Summary of the Invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 This is a flow chart of a voltage and current loop patrol configuration method based on an ICD model provided by the present invention. DETAILED DESCRIPTION

[0032] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0033] Example 1:

[0034] like Figure 1 As shown, this embodiment provides a voltage and current loop patrol configuration method based on the ICD model, including:

[0035] Obtain the ICD model file to be configured and parse it to obtain the key features of all signals in the ICD model to be configured;

[0036] Matching the key features obtained by analysis with the universal matching rules for voltage and current loop inspection to generate a voltage and current loop inspection model corresponding to the signal; wherein the universal matching rules for voltage and current loop inspection are determined based on the correlation between the functional features of the voltage and current loop inspection of the smart substation and the ICD model;

[0037] The voltage and current loop patrol model is combined with the basic information of the ICD model to be configured, and a one-to-one mapping relationship between the ICD model file to be configured and the voltage and current loop patrol model file is established.

[0038] The specific steps are as follows:

[0039] Step 1: Determine the general matching rules for voltage and current loop inspection, including:

[0040] Step 1.1: Obtain the ICD model specifications and voltage and current loop inspection specifications.

[0041] Specifically, the ICD model standard is the power industry's standard for describing relay protection equipment capabilities. In this embodiment, the ICD model standard is Q / GDW_1396-2012 IEC_61850 Engineering Relay Protection Application Model and Q_CSG1203065-2020 IEC61850 General Application Model for Substation Engineering.

[0042] The voltage and current circuit inspection specification standard is the China Southern Power Grid enterprise standard "Intelligent Recorder Intelligent Inspection Function Description".

[0043] Step 1.2: Divide the voltage and current loop related signals in the ICD model standard into three types of signals: switching signals, analog signals, and control signals, and extract the key features of the three types of signals.

[0044] Key signal features include: The reference feature uniquely describes the path of a signal instance in the ICD model, consisting of the logical device (LD), logical node (LN), prefix (prefix), instance number (inst), data (DO), functional constraint (FC), and data attribute (DA). For example, PROT / OvCurPTOC2$ST$Op; this path consists of LDName+ / +prefix+PTOC+inst+$+ST+$+DO+$+DA, revealing the corresponding information for the logical device (LD), logical node (LN), prefix (prefix), instance number (inst), data (DO), functional constraint (FC), and data attribute (DA). The desc feature is a Chinese description of the signal's specific meaning in the ICD model, such as differential quick-break action.

[0045] Key signal features include the logical node (LN), prefix (prefix), instance number (inst), data (DO), function constraint (FC), and data attribute (DA) in the voltage / current loop signal reference, and the standard Chinese description features in the voltage / current loop signal desc. For example, a signal in the protection analog data set (dsRelayAin) in the ICD model has a reference of PROT / MMXU$MX$A$phsA, and the corresponding desc is: Channel 1 Uncompensated Differential Current Phase A. Its key features are $A$ (data), phsA (data attribute), differential current, and phase A. The feature "$A$" indicates that the signal type is current, the features "phsA" and "phase A" indicate that the current phase sequence is phase A, and the feature "differential current" indicates that the current type is differential current.

[0046] Since the construction of smart substations has the same requirements for smart station relay protection equipment, all relay protection equipment must have ICD files and must be tested, certified and filed. The ICD file can be obtained from the filing based on the software version and check code of the protection device. At the same time, due to the requirements of the nine unified devices, all devices support uploading the device configuration file via FTP, so the ICD file can also be obtained from the relay protection device.

[0047] The basic information of the ICD model includes: manufacturer, configuration version number configVersion and model type. The configuration version number configVersion includes the configuration time, product function type, applicable region, and corresponds to a unique ICD model.

[0048] Step 1.3: Associate the obtained key features with the voltage and current loop patrol function configuration items to obtain the voltage and current loop patrol general matching rules.

[0049] Step 1.3 also includes, after obtaining the voltage and current loop patrol universal matching rule, corresponding a plurality of logical combinations of different key features to a voltage and current loop patrol function configuration item to obtain a voltage and current loop patrol universal matching rule model. The logical combination includes AND, NOT, and OR.

[0050] Step 1.3 The specific steps include:

[0051] 1) Based on the extracted features of reference and desc from the ICD model and analysis combined with the voltage and current patrol function configuration requirements, the extracted feature combinations are associated with the voltage and current patrol function configuration. For example, in step 1, given the reference (PROT / MMXU12$MX$A$phsA) and description (channel 1 uncompensated differential current, phase A), based on the extracted features ($A$, phsA, differential current, phase A) and the voltage and current patrol function specifications, this signal is associated with the voltage and current loop patrol function keyword: Ia, and the decision rule configuration is: 5 (dual protection and acquisition unit pairwise comparison).

[0052] 2) Model the relationship between the logical combination of features and the configuration items of the voltage and current patrol function. For example, the model can be established for the example in 1):

[0053]

[0054]

[0055] The refKey and descKey in the above rules represent the logical combination of the reference and desc features of the signal respectively, "|" indicates the logical relationship between features, and "!" indicates the non-logical relationship between features. The refKey and descKey of the same rule also have a logical relationship; the values corresponding to rule 1 (id="1") and rule 2 (id="2") in the keyword generation rule are both Ia, which means that the two rules are logically ORed.

[0056] Step 2: Obtain the ICD model file to be configured and parse it to obtain the key features of all signals in the ICD model to be configured.

[0057] Step 3: Match the key features obtained by analysis with the general matching rules of voltage and current loop inspection to generate a voltage and current loop inspection model corresponding to the signal.

[0058] For example, in a line protection ICD model, the dsRealyAin dataset contains signals with reference and desc values of PORT / meaMMXN4$MX$Amp and differential current phase A ICa, respectively. When matching the general rules in step 1, keyName matches rule 3 of the keyword generation rules, with a value of Ia; and judgeRule matches rule 3 of the decision rule generation rules, with a value of 5 (pairwise comparison of two protection and acquisition units).

[0059] Step 3 also includes: saving the voltage and current loop inspection model.

[0060] The manufacturer manufacturer, configuration version number configVersion and model type type are combined in the format of manufacturer+@+type+@+configVersion as the file name of the voltage and current loop patrol model.

[0061] For example, in the ICD model, the manufacturer is GDNZ, the type is PSIU-601ILB-DG-N, and the configVersion is V1_01. The file name of the saved voltage and current loop inspection model is GDNZ@PSIU-601ILB-DG-N@V1_01.

[0062] Step 4: Combine the basic information of the voltage and current loop patrol model with the ICD model to be configured, and establish a one-to-one mapping relationship between the ICD model file to be configured and the voltage and current loop patrol model file.

[0063] The present invention analyzes the correlation between the voltage and current loop patrol function characteristics of the intelligent substation and the capability description model of the intelligent relay protection equipment, extracts key features and constructs a universal function rule model. The ICD models of relay protection equipment of different voltage levels and different types can quickly match and identify the signals reference and desc in the ICD model according to the universal rule model constructed above, and generate a voltage and current loop patrol model. At the same time, according to the configVersion, manufacturer, and type information in the ICD model, a one-to-one mapping relationship between the ICD model file and the generated voltage and current loop patrol model is established, thereby ensuring the universality of the generated voltage and current loop patrol model and avoiding the need to regenerate the voltage and current loop patrol model for the same type of intelligent relay protection equipment in each intelligent substation, thereby improving debugging efficiency, shortening power outage time, and meeting the requirements of rapid deployment of the voltage and current loop patrol function of the intelligent substation and shortening power outage time.
