[0039] Reference is now made to the accompanying drawings to describe exemplary embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to disclose the present invention in detail and completely, and to fully convey the scope of the present invention to those skilled in the art. The terms in the exemplary embodiments shown in the drawings are not limitations on the present invention. In the drawings, the same units / components are denoted by the same reference numerals.

In addition, it can be understood that the terms defined in the commonly used dictionary should be understood to have a meaning consistent with the context of their related fields, and should not be understood as idealized or overly formal meanings.

[0041] Figure 1 It is a flowchart of an on-line verification method for virtual circuits during the transition period of interval-by-interval transformation according to a preferred embodiment of the present invention.

[0042] In terms of the monitoring of relay protection virtual circuits, the prerequisite for on-line operation monitoring of relay protection virtual circuits is to be able to completely collect comprehensive data related to the operation of relay protection equipment. In the new generation of substation secondary systems that are independently controllable, safe and reliable, the process layer network is cancelled, and some GOOSE information needs to be collected from the station control layer network, and the data stream has different characteristics from the past. To completely collect all data related to relay protection equipment, it is necessary to rely on the functions of the original fault recorder and network analyzer. The fault recording function has the ability to collect analog quantities, switch quantities, and generate recording files, etc., and is the main support for the fault recording and analysis of relay protection equipment. The network analysis function can record and analyze SV / GOOSE messages and CMS communication messages of relay protection equipment, perform traffic statistics, and alarm for message anomalies and traffic anomalies, and is an essential information support for diagnosing the secondary circuits related to relay protection equipment. The combination of these two functions, plus the collection of CMS communication data of relay protection equipment, can realize the acquisition of comprehensive information of relay protection equipment. It provides a solid foundation for realizing the on-line verification of virtual circuits during the transition period of interval-by-interval transformation.

[0043] In order to meet the construction and development needs of upgrading the traditional substation secondary system to a new generation of substation secondary systems that are independently controllable, safe and reliable, with the feasibility and safety of the relay protection interval-by-interval power outage transformation transition stage as the goal, minimize the configuration information changes of cross-interval equipment during the substation transformation process, and ensure the correctness of information interaction and the effectiveness of secondary circuits during the interval-by-interval transformation process through on-line verification of virtual circuits during the transformation transition period.

[0044] The step-by-step transformation mainly aims at transforming existing conventional substations into a new generation of self-controlled, safe and reliable substations. The virtual circuit verification system for step-by-step transformation mainly includes intelligent fault recording devices, untransformed conventional devices, secondary information conversion devices, and intelligent devices after transformation.

[0045] The step-by-step transformation process is divided into two cases: first, the interval transformation (line interval, transformer interval, etc.) is carried out, and then the cross-interval equipment (bus protection, etc.) is transformed; second, the cross-interval equipment (bus interval, etc.) is transformed first, and then the interval transformation (line interval, transformer interval, etc.) is carried out.

[0046] The intelligent fault recording device monitors the untransformed conventional devices, secondary information conversion devices, and intelligent devices after transformation through the CMS network. It monitors the secondary information conversion devices and intelligent devices after transformation through the GOOSE network. And the virtual circuit verification is realized in the intelligent fault recording device.

[0047] Among them, the CMS information sent by the untransformed conventional device, the CMS information sent by the secondary information conversion device, the CMS information sent by the intelligent device after transformation, the GOOSE information sent by the intelligent device after transformation, and the GOOSE information sent by the secondary information conversion device are used as the comparison information sources.

[0048] The CMS information sent by the untransformed conventional device is used as the first verification information, the CMS information sent by the secondary information conversion device is used as the second verification information, the CMS information sent by the intelligent device after transformation is used as the third verification information, the GOOSE information sent by the secondary information conversion device is used as the fourth verification information, and the GOOSE information sent by the intelligent device after transformation is used as the fifth verification information.

[0049] Since the step-by-step transformation only involves the information conversion of GOOSE-related information through the information conversion device, only the GOOSE-related virtual circuits are verified.

[0050] As Figure 1 shown, the present invention provides an online verification method for virtual circuits during the step-by-step transformation transition period. The method includes:

[0051] Step 101: Extract multiple verification information in the first virtual circuit during the step-by-step transformation through the secondary information conversion device. The verification information includes: the CMS information reported by the untransformed conventional device, the CMS information reported by the secondary information conversion device, the CMS information reported by the intelligent device after transformation, and the GOOSE information reported by the intelligent device after transformation;

[0052] Preferably, extracting multiple verification information in the first virtual circuit during the step-by-step transformation through the secondary information conversion device includes:

[0053] Obtain the CCD file of the secondary information conversion device, parse the virtual terminal information in the CCD file GOOSESUB, identify the circuits connected to the virtual terminals, and based on the identified external signal description desc and internal signal description intAddrdesc, extract multiple check information in the first virtual circuit during the interval-by-interval transformation.

[0054] In the improved intelligent device of the present invention, the virtual circuit check is performed by selecting and extracting check information through the CCD file of the improved intelligent device, + identifying the CMS information sent by the unmodified conventional device, the CMS information sent by the secondary information conversion device, and the CMS information sent by the improved intelligent device, and identifying the GOOSE information sent by the secondary information conversion device through the IEDname, APPID, MAC address, and the name "intAddr desc". That is, compare the first check information, the second check information, the third check information, and the fourth check information.

[0055] Step 102: Extract multiple check information in the second virtual circuit during the interval-by-interval transformation through the improved intelligent device. The check information includes: the CMS information reported by the unmodified conventional device, the CMS information reported by the secondary information conversion device, the CMS information reported by the improved intelligent device, and the GOOSE information reported by the secondary information conversion device.

[0056] Preferably, extracting multiple check information in the second virtual circuit during the interval-by-interval transformation through the improved intelligent device includes:

[0057] Obtain the CCD file of the improved intelligent device, parse the virtual terminal information in the CCD file GOOSESUB, identify the circuits connected to the virtual terminals, and based on the identified external signal description desc and internal signal description intAddr desc, extract multiple check information in the second virtual circuit during the interval-by-interval transformation.

[0058] In the improved intelligent device of the present invention, the virtual circuit check is sent by selecting and extracting check information through the CCD file of the information conversion device. By parsing the virtual terminal information in the CCD file GOOSESUB, identify and extract the circuits connected to the virtual terminals, and through the external signal description desc and internal signal description intAddr desc, identify the CMS information sent by the conventional device before, the CMS information sent by the secondary information conversion device, the CMS information sent by the improved intelligent device, and the GOOSE information sent by the improved intelligent device, and identify the GOOSE information sent by the secondary information conversion device through the IEDname, APPID, MAC address. That is, compare the first check information, the second check information, the third check information, and the fifth check information.

[0059] Step 103: When there is a change in one of the multiple check information in the first virtual loop or the second virtual loop, compare the changed check information with the remaining check information in the first virtual loop or the second virtual loop;

[0060] Step 104: When the comparison result of the changed check information with the remaining check information in the first virtual loop or the second virtual loop is consistent, the virtual loops during the interval transformation pass the check one by one.

[0061] Preferably, the interval transformation includes:

[0062] First perform interval transformation and then perform cross-interval equipment transformation; or

[0063] First perform cross-interval equipment transformation and then perform interval transformation.

[0064] For each virtual loop connection identified in the CCD file of the intelligent device and the CCD file of the information conversion device after the transformation in the present invention, there should be a check loop, and four corresponding check information are compared. Whenever one of the four check information changes, a comparison is triggered. When the four check information are all consistent, the check passes; otherwise, the check fails and an alarm is issued.

[0065] The present invention provides an on-line check method for virtual loops during the interval transformation transition period, which ensures the consistency between the configuration file and the actual configuration parameters of the process layer operating equipment during the interval transformation transition period, the correctness of secondary information conversion, and improves the reliability of the configuration file. The invention results will promote the practical application process of the new generation of substation secondary systems that are independently controllable, safe and reliable, and ensure the safe and reliable operation of the new generation of substation secondary systems during the transition period. It realizes the replacement transformation of the new generation of substation relay protection based on the single-interval power-off mode, and can better promote the domestic substitution of existing substations and the large-scale application of the new generation of substations in the future under the requirements of ensuring the safe operation of the power grid and power supply guarantee.

[0066] In the process layer of the new generation of substation with independent control, safety and reliability of the present invention, a collection and execution unit is used to realize the collection of primary analog quantities and switch quantities, and receive the trip and control commands of the protection and control equipment to realize the trip of the switch. For cross-interval secondary equipment, such as a bus protection device typically, to ensure that the primary bus is not without protection for a long time during the transformation, before the specific commissioning conditions of the new digital bus protection device, it must be ensured that the old bus protection device can still provide protection for the bus.

[0067] For example, a 220 kV conventional substation, such as Figure 2As shown in the figure, the line bay 1 on the 220 kV bus has completed the bay transformation, and the installation of the acquisition and execution unit and the intelligent line protection has been completed. At this time, for the conventional 220 kV bus protection device, it is impossible to transmit analog signals, switch signals, etc. to the acquisition and execution unit and the intelligent line protection through optical cables. Similarly, the digital bus protection cannot receive analog signals from the untransformed bays through cables and cannot directly trip through cables. If no relevant measures are taken, both the new and old bus differential protections may face the dilemma of being unable to be put into operation, and the bus will lose protection. By using the interface conversion device, the cable switch signals of the primary equipment can be converted into GOOSE signals to realize the uploading of switch and disconnector signals to the intelligent protection equipment; the GOOSE trip signal of the intelligent protection can be converted into a cable output to realize the tripping of the switch.

[0068] Firstly, it is the verification of the virtual terminal loop received by the intelligent device after transformation. As Figure 3 shown in the figure, the line bay 1 has completed the interval-by-interval transformation, but the bus has not been transformed. At this time, the bus protection needs to perform signal conversion between conventional quantities and digital quantities through the bus interface conversion device.

[0069] By reading the CCD files of the P_L2201A protection device and the MIL2201A acquisition and execution unit in the transformed bay, the virtual terminal information related to the untransformed bus protection P_M2201A is screened out, and other verification information is searched and compared through the external signal description desc and the internal signal description intAddr desc. The corresponding signal is searched and compared through the external signal description desc in the dsRelayDin data set of the PROT logical device in the untransformed bus protection and the interface conversion device S1 access point. The corresponding signal is searched and compared through the internal signal description intAddr desc in the dsRelayDin data set of the PROT logical device in the S1 access point of the transformed line protection. The GOOSE information sent by the secondary information conversion device is identified through the IEDname, APPID, and MAC address. By comparing these four verification information, the purpose of verifying the virtual loop received by the transformed intelligent device is achieved. Among them, when all four pieces of information are consistent, the virtual loop verification passes; otherwise, it fails.

[0070] By reading the CCD file of the interface conversion device, the virtual terminal information related to the reformed interval P_L2201A protection device and MIL2201A acquisition and execution unit is found, and other verification information is searched and compared through the external signal description desc and the internal signal description intAddr desc. The corresponding signal is searched and compared in the dsRelayDin data set of the PROT logical device at the S1 access point of the un-reformed bus protection and interface conversion device through the internal signal description intAddr desc. The corresponding signal is searched and compared in the dsRelayDin data set of the PROT logical device at the S1 access point of the reformed line protection through the external signal description desc. The GOOSE information sent by the reformed interval P_L2201A protection device and MIL2201A acquisition and execution unit is identified through IEDname, APPID, and MAC address. By comparing these four verification information, the purpose of verifying the virtual circuit sent by the reformed intelligent device is achieved. Among them, when the four pieces of information are all the same, the virtual circuit verification passes; otherwise, it fails.

[0071] For each virtual circuit connection identified in the CCD file of the reformed intelligent device and the CCD file of the information conversion device, there should be a verification circuit, and there are corresponding four verification information for comparison. Whenever one of the four verification information changes, a comparison is triggered.

[0072] The present invention proposes an on-line verification method for virtual circuits during the interval-by-interval transformation transition period, including: interval-by-interval transformation and on-line verification of virtual circuits.

[0073] The present invention generates a comparison circuit by extracting the CCD files of the reformed intelligent device and the secondary information conversion device, analyzes the CMS and GOOSE information accessed by the intelligent fault recording device, extracts five verification information, and realizes the on-line verification of virtual circuits during the interval-by-interval transformation transition period through the consistency comparison of the verification information.
