Description

Intelligent substation telecontrol system equipment testing method, device and system

Technical Field

The invention relates to the technical field of intelligent substation signal testing, in particular to a method, a device and a system for testing telecontrol system equipment of an intelligent substation.

Background

Currently, with the rapid development of national power systems, intelligent substations have been widely used. Due to the characteristics of electric energy production, an energy center and a load center are generally far apart, and an electric power system is distributed in a wide region, wherein the distances between a power plant, a transformer substation, an electric power dispatching center and users are dozens of kilometers in a short distance, and hundreds of kilometers or even thousands of kilometers in a long distance. However, to manage and monitor the operation conditions of a plurality of power plants, substations and power devices and components with wide distribution, the control information or feedback data cannot be transmitted by the common mechanical or electrical connection, and the control information or feedback data must be realized by means of a telemechanical technology. The telecontrol technology generally converts the operating conditions (including on-off states, operating parameters of equipment and the like) of each power plant, substation and the like into a signal form convenient for transmission, adds a protection measure to prevent external interference in the transmission process, and transmits the modulated signal to a dispatching station through a special information channel. The central station of the dispatching station is subjected to inverse modulation, and is restored into signals corresponding to the operation conditions of a power plant, a transformer substation and the like, and then the signals are displayed for monitoring by dispatching personnel. In addition, some control commands of the scheduling personnel can also be transmitted to the power plant, the substation and the like. As shown in fig. 1, currently, in an intelligent substation, a telecontrol system device 11 is arranged on a station level network 12, and can receive messages of a protective device 13, a measurement and control device 14, a safety and stability device 15 and the like of a bay level to communicate with devices of the bay level and devices of a process level (such as a merging unit device 16 and an intelligent terminal device 17); in addition, the telemechanical system device 11 can be connected with the scheduling data network 18 through a port of a 101 protocol, a 104 protocol or a 674 protocol, so as to perform data interaction with the scheduling master station 19.

At present, in order to ensure the normal operation of telemechanical system equipment, the telemechanical system equipment needs to be tested, and the current testing method is that after a station control layer network and a scheduling data network have conditions (network construction is completed), excitation quantities are actually applied to a merging unit device, an intelligent terminal device, a protection device, a measurement and control device, a security and stability device and the like, and finally whether data are completely consistent with the applied excitation quantities, including numerical values, positions, states, channel serial numbers and the like, is checked at a scheduling master station; in addition, the remote control and remote regulation commands are issued at the dispatching master station, and whether the switch, the disconnecting link, the transformer gear and the like correctly act or not is checked on the intelligent terminal equipment site.

However, the test process of the telemechanical system equipment in the prior art has many problems, firstly, the test of the telemechanical system equipment depends on the construction of a station control layer network, a scheduling data network and a scheduling master station, and the construction of the scheduling data network and the scheduling master station generally has conditions only when the intelligent substation is put into operation, so that the test time of the telemechanical system equipment is limited; secondly, the test of the existing telecontrol system equipment needs to be completed by depending on close cooperation of manpower at three positions of a transformer substation, the telecontrol system equipment and a dispatching master station, and the work coordination difficulty is high; thirdly, the remote signaling amount of the test of the existing telecontrol system equipment is huge (for example, a common 500kV transformer substation, the remote signaling amount is about 8000), so that the workload of testing by means of manual mode is extremely large.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 2, an embodiment of the present invention provides a method for testing a telecontrol system device of an intelligent substation, including:

step 201, obtaining a pre-imported total station system configuration file SCD and a telecontrol information point table.

The telecontrol information point table comprises description information of MMS signal points of each interval layer device, signal description values corresponding to the description information respectively and scheduling point addresses corresponding to the description information respectively. The MMS (messaging specification in ISO/IEC 9506) signal points represent signal test points of devices in the bay level equipment, such as an a-phase 5042 breaker position, a bay 1A phase current, a breaker 1 position, etc. in the bay level equipment.

Step 202, sequentially acquiring MMS signal points corresponding to the description information from the total station system configuration file SCD according to the signal description values, and generating and sending MMS detection messages of the MMS signal points to telemechanical system equipment.

The total station System Configuration Description (SCD) records MMS signal point information. The total station system configuration file SCD is a configuration file used in the IEC 61850 standard for understanding the structure and layout of the whole substation.

And 203, receiving a telecontrol signal generated by the telecontrol system equipment according to the MMS detection message.

And step 204, judging whether the telecontrol system equipment normally works according to the telecontrol signal, the MMS detection message and the scheduling point address in the telecontrol information point table.

The embodiment of the invention provides a method for testing telecontrol system equipment of an intelligent substation, which can automatically test the telecontrol system equipment in the processes of remote measurement and remote signaling according to a pre-introduced SCD (total station system configuration file) and a telecontrol information point table without depending on the construction of a station control layer network, a scheduling data network and a scheduling master station and without the cooperative operation of personnel, and solves the problems that the test process of the telecontrol system equipment in the prior art is influenced by the construction of the station control layer network, the scheduling data network and the scheduling master station, and the test difficulty is complicated due to the cooperative operation of too many personnel.

In order to enable those skilled in the art to better understand the present invention, a more detailed embodiment is listed below, and as shown in fig. 3, an embodiment of the present invention provides a method for testing a telecontrol system device of an intelligent substation, including:

step 301, obtaining a pre-imported total station system configuration file SCD and a telecontrol information point table.

The telecontrol information point table comprises description information of MMS signal points of each interval layer device, signal description values corresponding to the description information respectively and scheduling point addresses corresponding to the description information respectively; the MMS signal point is a signal test point in the spacer layer equipment.

The telemechanical information table herein may include description information of MMS signal points of each bay level device (i.e., original signal point description of the substation in table 1 below), signal description values corresponding to each description information (i.e., Ref value in table 1 below), and scheduling point addresses corresponding to each description information. In addition, the telecontrol information table can also comprise the description of the signal points of the dispatching end, the number of the telecontrol points, the addresses of the monitoring points, the description information of the signal points of the monitoring ends, the information of the signal types and the like. Which can be shown in table 1 below:

table 1:

there may be many telecontrol information points (a row of information in table 1) for remote control, remote measurement and remote signaling in table 1, and only these are listed in table 1 above, and it should be understood that a person skilled in the art may set more telecontrol information points in the telecontrol information table without creative work, and may sequentially perform a test of the telecontrol system device according to each telecontrol information point. The telemechanical system device in the embodiment of the present invention may be a single telemechanical device, or may be a telemechanical system device composed of a plurality of devices, for example, a distributed system composed of a plurality of telemechanical devices, or the like.

In addition, the telecontrol information table (as shown in table 1) in the embodiment of the present invention is an information point table updated to implement automatic testing of the telecontrol system equipment, and is not an information point table scheduled currently (as shown in table 2 below), and this telecontrol information table needs to be added with a Ref value, which may be obtained and derived in advance from the total station system configuration file SCD. The meaning of the Ref value in the telecontrol information table is that since the description information of the MMS signal point of the spacer layer device is generally described by natural language (such as chinese, english, etc.) of those skilled in the art, there is no strict specification, and the randomness is large, so that a great error occurs in the subsequent test and matching through the description information. The Ref value is obtained and derived in the total station system configuration file SCD in advance, and the Ref value is unique in the total station system configuration file SCD, so that the Ref value can be used for matching test.

Table 2:

step 302, sequentially obtaining MMS signal points corresponding to the description information from the total station system configuration file SCD according to the signal description values, obtaining data set names and report names corresponding to the MMS signal points corresponding to the description information, and generating digital quantity or analog quantity of the MMS signal points corresponding to the description information.

It should be noted that, here, the remote signaling process and the remote measurement process of the telemechanical system device can be performed through steps 301 to 310, where the remote signaling process and the remote measurement process refer to a process in which the protection device, the measurement and control device, the stability device, the merging unit device, the intelligent terminal device, and the like at the bay level transmit an MMS message to the telemechanical system device through the station control layer network, and then the MMS message is converted into a remote control signal with a protocol such as 101, 104, 674, and the like through the telemechanical system device, and finally reaches the scheduling master station through the scheduling data network.

When testing telesignalling telemechanical system equipment, selecting a telemechanical information point (for example, the 500kV 1 bus first set of merging unit device in table 1 above is locked) with a signal type of telesignalling from a telemechanical information table, that is, acquiring a signal description value corresponding to the telesignalling (for example, the 500kV 1 bus first set of merging unit device in table 1 above is locked, and its Ref value is ML500API/lln0.gocb0), and then acquiring a corresponding MMS signal point in a total station system configuration file SCD according to the Ref value, so as to acquire a corresponding data set name (dsAlarm) and a report name (brcbAlarm), and the like. In addition, when testing telemechanical system equipment for a telesignaling process, it is necessary to generate a digital quantity of an MMS signal point corresponding to description information, for example, a state of generating a lock of the first set of merging unit devices of the 500kV 1 bus is set to "1" or "0".

When testing telemechanical system equipment in a telemetry process, a telemechanical information point (for example, a first value of phase current at interval 1A in table 1 above) with a signal type of telemetry is selected from a telemechanical information table, that is, a signal description value corresponding to the telemetry (for example, a first value of phase current at interval 1A in table 1 above, with a Ref value of MEAS/MMXU1$ MX $ a. phsa) needs to be obtained, and then a corresponding MMS signal point is obtained from a total station system configuration file SCD according to the Ref value, so that a corresponding data set name (dsAlarm) and a report name (brcbAlarm) and the like can be obtained. In addition, when testing telemechanical system equipment for performing a telemetry process, it is necessary to generate an analog quantity of an MMS signal point corresponding to description information, for example, a primary value of phase current at an interval of 1A is 3000A.

And step 303, generating an MMS detection message of the MMS signal point corresponding to the description information according to the data set name, the report name, the signal description value and the digital quantity corresponding to the MMS signal point corresponding to the description information, or the data set name, the report name, the signal description value and the analog quantity corresponding to the MMS signal point corresponding to the description information.

And step 304, sending the MMS detection message of the MMS signal point corresponding to the description information to telecontrol system equipment.

And 305, receiving a telecontrol signal generated by telecontrol system equipment according to the MMS detection message.

The telecontrol signal here can adopt a 101 protocol, a 104 protocol or a 674 protocol.

And step 306, analyzing the telecontrol signal to obtain the address of the dispatching point of the telecontrol signal and the digital quantity or the analog quantity in the telecontrol signal.

Step 307, determining whether the address of the scheduling point of the telecontrol signal is the same as the address of the scheduling point in the telecontrol information point table, and determining whether the digital quantity in the telecontrol signal is the same as the digital quantity of the MMS signal point corresponding to the description information, or determining whether the address of the scheduling point of the telecontrol signal is the same as the address of the scheduling point in the telecontrol information point table, and determining whether the analog quantity in the telecontrol signal is the same as the analog quantity of the MMS signal point corresponding to the description information.

Steps

308, 309 or 310 are performed after step 307.

For example, when testing telemechanical system equipment in a telesignaling process, it is necessary to determine whether a scheduling point address of the telemechanical signal is the same as a scheduling point address in the telemechanical information point table, and determine whether a digital quantity in the telemechanical signal is the same as a digital quantity of an MMS signal point corresponding to the description information.

When testing telemechanical system equipment in a telemetry process, whether the address of the scheduling point of the telemechanical signal is the same as the address of the scheduling point in the telemechanical information point table or not needs to be judged, and whether the analog quantity in the telemechanical signal is the same as the analog quantity of the MMS signal point corresponding to the description information or not needs to be judged.

And 308, when the address of the dispatching point of the telecontrol signal is the same as the address of the dispatching point in the telecontrol information point table, and the digital quantity in the telecontrol signal is the same as the digital quantity of the MMS signal point corresponding to the description information, determining that the telecontrol system equipment normally works in the telecontrol process.

For example, for the locking of the first merging unit device of the 500kV 1 bus in table 1 above, after the address of the dispatching point of the telecontrol signal is obtained, the address is compared with the address 3001 of the dispatching point in the telecontrol information point table, and after the digital quantity in the telecontrol signal is obtained, the digital quantity of the MMS signal point corresponding to the description information, that is, the locked state of the first merging unit device of the 500kV 1 bus, is compared, and if the two comparisons are the same, it is determined that the telecontrol system apparatus is operating normally in the telecommand process. Otherwise, the following step 310 occurs, and the telemechanical system device does not operate normally.

Step 309, when the address of the scheduling point of the telecontrol signal is the same as the address of the scheduling point in the telecontrol information point table, and the analog quantity in the telecontrol signal is the same as the analog quantity of the MMS signal point corresponding to the description information, determining that the telecontrol system device normally works in the telemetry process.

For example, after obtaining the scheduling point address of the telecontrol signal, the interval 1A phase current primary value in table 1 above is compared with the scheduling point address 2001 in the telecontrol information point table, and after obtaining the analog quantity in the telecontrol signal, the interval 1A phase current primary value 3000A is compared with the analog quantity of the MMS signal point corresponding to the description information. Otherwise, the following step 310 occurs, and the telemechanical system device does not operate normally.

And 310, when the address of the dispatching point of the telecontrol signal is different from the address of the dispatching point in the telecontrol information point table, or when the digital quantity in the telecontrol signal is different from the digital quantity of the MMS signal point corresponding to the description information, or when the analog quantity in the telecontrol signal is different from the analog quantity of the MMS signal point corresponding to the description information, determining that the telecontrol system equipment does not normally work.

and step 205, generating and sending a remote control signal to the telecontrol system equipment according to the description information of the MMS signal point of the interval layer equipment in the telecontrol information point table and the scheduling point address corresponding to the description information.

And step 206, receiving an MMS message generated by the telecontrol system equipment according to the remote control signal.

And step 207, judging whether the telecontrol system equipment works normally according to the MMS message, the remote control signal and the signal description value in the telecontrol information point table.

Specifically, as shown in fig. 5, in order to enable a person skilled in the art to better understand the

above steps

201, 205 to 207, a more detailed embodiment is listed below, and an embodiment of the present invention provides a method for testing a telecontrol system device of an intelligent substation, including:

step 401, obtaining a pre-imported total station system configuration file SCD and a telecontrol information point table.

And step 402, generating a digital quantity value corresponding to the description information according to the description information of the MMS signal points of the spacer layer equipment.

It should be noted that, here, the testing of the telemechanical system device in the remote control process may be performed through steps 401 to 409, where the remote control process refers to a process in which the scheduling master station sends a remote control signal using a protocol such as 101, 104, 674 or the like to the telemechanical system device through the scheduling data network, and after the remote control signal is converted into an MMS message by the telemechanical system device, the remote control signal is sent to the protection device, the measurement and control device, the stability and security device, the merging unit device, the intelligent terminal device, or the like of the bay layer through the station control layer network.

When testing the telecontrol system equipment in the remote control process, a telecontrol information point (for example, 5051 circuit breaker 1 position in table 1 above) with a signal type of remote control is selected from the telecontrol information table, and when testing the telecontrol system equipment in the remote control process, a digital magnitude value corresponding to the description information needs to be generated, for example, the state of the position of the circuit breaker 1 is generated to be "0" or "1", where "0" represents closing of the circuit breaker 1, and "1" represents opening of the circuit breaker 1.

And step 403, generating a remote control signal according to the description information of the MMS signal point of the spacer layer equipment, the scheduling point address corresponding to the description information and the digital quantity value corresponding to the description information.

And step 404, sending the remote control signal to the telecontrol system equipment.

And 405, receiving an MMS message generated by the telecontrol system equipment according to the remote control signal.

Step 406, analyzing the MMS message, and obtaining a signal description value and a numerical value in the MMS message.

Step 407, determining whether the signal description value in the MMS message is the same as the signal description value in the telemechanical information table, and determining whether the numerical value in the MMS message is the same as the numerical value corresponding to the description information.

Step 408 or step 409 is performed after step 407.

And step 408, when the signal description value in the MMS message is the same as the signal description value in the telecontrol information table, and the numerical value in the MMS message is the same as the numerical value corresponding to the description information, determining that the telecontrol system equipment normally works in the remote control process.

For example, for the 5051 breaker 1 position in the above table 1, after the signal description value in the MMS message is obtained, the obtained signal description value is compared with the signal description value in the telemechanical information table, namely, the Ref value CTRL/CSWI1$ CO $ Pos, and after the obtained digital magnitude value in the MMS message is compared with the digital magnitude value corresponding to the description information, namely, the state position of the breaker 1 position, and if the two comparisons are the same, it is determined that the telemechanical system device is normally operated in the remote control process. Otherwise, the situation of the subsequent step 409 occurs, and the telemechanical system device does not work normally.

Step 409, when the signal description value in the MMS message is different from the signal description value in the telecontrol information table, or the numerical value in the MMS message is different from the numerical value corresponding to the description information, determining that the telecontrol system equipment does not normally work in the remote control process.

For remote control, remote measurement and remote signaling tests performed by adopting the contents in the telecontrol information table, test results can be recorded according to each telecontrol information point, and finally a test report file can be formed for related workers to inquire and watch.
