Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. 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.
At present, a flexible direct current transmission technology based on a Modular Multilevel Converter (MMC) is popularized and applied in an electric power system. Along with the continuous improvement of voltage grade and the continuous increase of transmission capacity, the number of converter valve sub-modules is rapidly increased to thousands of scales, and correspondingly, the requirements on the control scale, the control speed and the reliability of a Valve Base Controller (VBC) are higher and higher, and the test for the valve base controller is more and more detailed and strict. The existing test scheme has two implementation modes: one is to use a digital simulation system such as RTDS/RT-LAB and the like to test the basic functions of the valve base controller by matching with a real control protection system; the other method is to use a dynamic simulation system (namely a physical simulation system) and a converter valve equivalent system to cooperate with a real control protection system to test the functions of the valve base controller. Wherein, the dynamic simulation system is closer to the working condition of the on-site real system.
The converter valve submodule has more internal fault or state information, and other abnormity or faults are often caused in a linkage manner when the submodule is abnormal or has faults, and the test is difficult to realize by using the conventional flexible direct current simulation system or using a digital-to-analog system such as an RTDS/RT-LAB system and the like.
In addition, the fault of the converter valve is simulated by changing external conditions, so that the operation steps are complex, the automation level is low, and the testing efficiency is low. In addition, some fault types require manual testing, such as plugging and unplugging communication fibers. When more states and events are reported in the test process, the traceability is poor, and the sequence of the states and events is difficult to reproduce.
Based on this, the fault simulation mechanism and the fault simulation system for the flexible direct current converter valve provided by the embodiment of the invention can solve the technical problem that the early fault simulation process is difficult to realize in the process of detecting the flexible direct current converter valve in the prior art.
For the convenience of understanding the present embodiment, a detailed description will be given to a fault simulation mechanism and a system for a flexible dc converter valve disclosed in the embodiments of the present invention.
The first embodiment is as follows:
as shown in fig. 1, the fault simulation mechanism 1 for the flexible direct current converter valve according to the embodiment of the present invention includes: converter valve equivalent means 11, human-machine interface means 12 and fault setting means 13.
The human-computer interface device is used for determining a fault simulation instruction according to user input and transmitting the fault simulation instruction to the fault setting device. The human-machine interface device may be provided at an operator workstation (OWS for short). As shown in fig. 2, through the OWS fault setting human-machine interface, an operator or a tester can set the number and the fault type of sub-modules with faults on the interface, and the sub-modules are divided into 6 labels according to 6 bridge arms: a +/A-/B +/B-/C +/C-, the lower half of the diagram is a fault type. The OWS fault setting human-computer interface is convenient for testers to set various converter valve faults, the number and the types of sub-modules with faults can be set, the sub-modules with the faults can also be set to have the same or different types of faults at the same time, and the fault simulation system can also simulate cascading faults caused by single faults.
Furthermore, the human-computer interface device is in wired communication connection with the fault setting device. Specifically, the OWS fault setting man-machine interface and the fault setting device are connected through an RJ45 network, the connection rate is 100Mbps, the connection protocol is an Ethernet TCP/IP protocol, and bidirectional communication is achieved.
And the Fault Setting Device (FSD) is used for generating a fault setting signal according to the fault simulation instruction and transmitting the fault setting signal to the equivalent device of the converter valve. The fault setting device is connected with an OWS fault setting man-machine interface through an RJ45 network, receives a fault simulation instruction sent by the OWS, generates a fault setting signal after analysis is completed, and transmits the fault setting signal to the converter valve equivalent device through an optical fiber.
In practical application, the equivalent device of the converter valve is connected with the fault setting device in a wired communication mode. Preferably, the FSD fault setting device is connected with the equivalent device of the converter valve through optical fibers, the connection protocol is IEC60044-8, and bidirectional communication is achieved.
The converter valve equivalent device (SM) is used for controlling an internal converter valve submodule to execute fault simulation according to the fault setting signal, generating an instruction execution result and internal state information of the converter valve equivalent device according to the fault simulation condition, and transmitting the instruction execution result and the internal state information to the fault setting device.
Specifically, the converter valve equivalent device obtains an analysis result by analyzing the fault setting signal, and distributes the analysis result to the converter valve sub-modules inside, so as to control the converter valve sub-modules to perform fault simulation. As shown in fig. 3, in the rear view of the converter valve equivalent device, the leftmost board is a core board, which is connected to the FSD fault setting device using T1/R1; 9 integrated circuit boards on the right are SM boards and are connected with a core board through a back board. In this embodiment, the converter valve equivalent device receives and analyzes the fault setting signal, and distributes the fault setting signal to the corresponding SM submodule, that is, the right troubled 9 boards, and finally the SM submodule realizes fault simulation.
The fault setting device is also used for generating event return information and state return information according to the instruction execution result and the internal state information and transmitting the event return information and the state return information to the human-computer interface device. Specifically, the converter valve equivalent device transmits a control instruction execution result and device internal state information back to the fault setting device, and the fault setting device generates state and event report and transmits the state and event report back to the OWS human-computer interface device.
As a preferred embodiment of this embodiment, the fault setting device can also perform hardware and software upgrades to the converter valve equivalent device in order to support flexible fault simulation logic.
As shown in fig. 4, in the rear view of the fault setting device, the left RJ45 network is connected to the OWS human interface device, the middle T1/R1 to T11/R11 are respectively connected to the core boards of the 1 st to 11 th converter valve equivalent devices, R12 is connected to the IRIG-B code, and T12 is used as a backup.
Therefore, faults are set through the OWS human-computer interface device, and simulation instruction generation and issuing of one or more faults of one or more sub-modules are achieved simultaneously. Moreover, the fault setting device realizes the issuing of the fault setting instruction and the uploading of the state event report. In addition, the equivalent device of the converter valve is accurately matched with the fault setting device after hardware and software are upgraded, so that simulation of one or more faults and cascading faults thereof is realized.
As another embodiment of this embodiment, the OWS fault setting human-machine interface, the FSD fault setting device, and the SM valve equivalent device may be connected by a fiber network or a field bus such as RS485/PROFIBUS/MODBUS/CAN bus.
As shown in fig. 1, the fault simulation mechanism of the flexible dc converter valve further includes: a control protection device 14 and a valve control device 15. The control protection device (PCP) is used for controlling the equivalent device of the converter valve through the valve control device (VBC) according to a control signal transmitted by the human-computer interface device, so that the equivalent device of the converter valve can normally operate. The valve control device can also be called a valve base controller.
As shown in FIG. 1, the control protection device is connected with the human-computer interface device in a wired communication mode. The valve control device is connected with the control protection device in a wired communication mode. And the equivalent device of the converter valve is in wired communication connection with the valve control device. Preferably, the equivalent device of the converter valve is connected with the valve control device through optical fibers, and the connection protocol is IEC60044-8, so that bidirectional communication is realized. The automatic simulation of the faults of the flexible direct current converter valve is realized by controlling the protection device and the valve control device, and whether the response of the flexible direct current converter valve control device to the faults is timely and normal can be further tested.
For the prior art, in the process of detecting the flexible direct current converter valve, the early fault simulation process is difficult to realize. The fault setting device is added in the flexible direct current dynamic simulation system, hardware and software upgrading is carried out on the converter valve equivalent device, one or more faults and corresponding cascading faults of one or more converter valve sub-modules can be simulated, and therefore the valve control device can be tested more comprehensively and strictly.
In this embodiment, after hardware and software upgrade is performed on the converter valve equivalent device, a logic function which is more complex than that of a real converter valve control device and is beneficial to testing can be realized, for example, a fiber channel can be opened and closed remotely, and an upper tube and a lower tube of a remote control Insulated Gate Bipolar Transistor (IGBT for short) are driven without return and a power failure is controlled remotely, so that automation of a testing process is realized.
Example two:
as shown in fig. 5, the fault simulation system 2 for the flexible dc converter valve according to the embodiment of the present invention includes: the time service device 21 and the fault simulation mechanism of the flexible direct current converter valve provided in the first embodiment are provided.
The time service equipment is used for carrying out GPS time service on a fault setting device in the fault simulation mechanism of the flexible direct current converter valve. Specifically, the time service equipment is used for carrying out GPS time service on the fault setting device by transmitting an IRIG-B code to the fault setting device.
Preferably, the fault setting device is configured to add a time tag to the event report information and the state report information according to the GPS time service result. The fault setting device is further used for arranging the event return information and the state return information according to the time labels to obtain the event return information and the state return information based on the time sequence.
Specifically, as shown in fig. 5, R12 is an optical fiber IRIG-B receiving port, and the fault setting device can implement GPS time service by receiving an IRIG-B code, and time tags are marked on status and event reports, so that the time precision can reach microsecond level. The occurrence sequence of the states and the events can be arranged by utilizing the accurate time resolution, so that the analysis and the processing of the faults after the events are convenient.
Preferably, the fault setting device is further configured to transmit the event report information and the state report information based on the time sequence to the human-machine interface device. After GPS time service is realized by adding a fault setting device and accessing IRIG-B codes, the state and event return is marked with a time label with the precision of microsecond, so that the problem of poor traceability of multi-state and event return is solved, and even a fault avalanche test of a certain scale can be realized, namely a large number of sub-modules simultaneously generate a large number of faults of the same type. Therefore, the issuing of the fault setting instruction and the uploading of the state event return after the time marking are realized through the fault setting device.
