Description
Technical Field
The invention relates to the technical field of direct current transmission, in particular to a simulation test method and system for a valve control device.
Background
The function test of the valve control device is always a short board in the simulation test of the whole direct current transmission system, the control related function test of the valve control device is not fully emphasized, and the complete simulation test is not carried out. This is a relatively weak loop in the test system of the dc control protection system, and brings a certain risk to the operation of the dc power transmission system.
At present, related equipment manufacturers in China have a mode of establishing a moving die system for testing by using a simplified primary converter valve device and a valve control device, but the idea of carrying out detailed and accurate modeling on a converter valve based on a real-time simulation system and carrying out complete testing on the valve control function by connecting the valve control device and a control protection device is not realized all the time due to the condition limitations of a simulation platform, a simulation method and the like.
The conventional direct-current valve control device participates in the test more or less in the simulation test of the direct-current control protection system. In the conventional direct current engineering construction and debugging stage, although the valve control device participates in the real-time closed loop test of the direct current protection system, one valve arm in the simulation model is simulated by one switch signal, the trigger pulse is a long pulse with the duration of 6ms and is limited by the simulation platform, and the valve control function cannot be deeply and comprehensively tested.
In a model in the existing simulation test, a valve control function cannot be carefully tested. In the existing simulation test, a valve arm is simulated by a switching signal, and a long pulse with the duration of 6ms is used as a trigger pulse. In actual engineering, each valve arm is composed of a plurality of valve plates, and each valve plate has a single trigger pulse. The coarseness of the model results in the failure of the valve-controlled function to be embodied exhaustively at all, let alone carefully tested. For example, if the valve control device fails, some trigger pulses are lost, and simulation and test cannot be performed in the existing model test.
In the existing simulation test model, the valve control function cannot be deeply and comprehensively tested. In the existing model, some of the functionality of the valve module is not embodied in the software model. For example, the return signal of the valve plate in the valve module is not represented in the software model. When the multi-channel echo signal is lost, a protection action may be caused. The existing model lacks the design of the part, so the existing model does not have the capability of completely testing the valve control function.

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.
Referring to fig. 1, which is a schematic flow chart of a simulation testing method for a valve control device according to an embodiment of the present invention, the method includes:
and S110, receiving a test signal sent by the monitoring host.
Specifically, the test signal includes preset current and voltage parameters of the monitoring host to the valve module simulation board card and the bridge arm simulation board card, fixed value setting of valve control related logic is achieved, and if the preset voltage parameters judge an on or off state according to voltage information of the valve module simulation board card to the converter station valve plate, a trigger signal is sent. The monitoring host needs to modify the fixed value of the complementary pulse logic and modify the fixed value of the related function of the interface RPU.
And S120, responding to the test signal, judging a first running state of a valve plate of a converter station in the direct current transmission system according to first simulation running information sent by the digital real-time simulator, and generating a first trigger pulse signal.
Specifically, the digital real-time simulator simulates according to the first running state sent by the converter station control protection device to obtain the first simulated running information, and sends the first simulated running information to the valve module simulation board card; the first simulation operation information comprises voltage information of a valve plate of the converter station;
and the valve module simulation board card judges the on-off state of the valve plate according to the first simulation operation information to generate the first trigger pulse signal.
It can be understood that the first operating state is operating information of a valve plate of a converter station in the direct current transmission system, such as current and voltage information and fault information; the first simulation operation information is voltage information of a converter station valve plate, the voltage information is subjected to simulation detection by a digital real-time simulator according to the received first operation state, and generated detection voltage information is sent to a valve module simulation board card.
S130, sending the first trigger pulse signal to a valve control system so that the valve control system can process a first running state of a valve plate of the converter station;
and S140, sending the first trigger pulse signal to the monitoring host to enable the monitoring host to monitor the direct current power transmission system.
The monitoring host can realize on-line monitoring of related valve control logic and collect running state data of all equipment in the direct current transmission valve control device simulation system.
Preferably, the first trigger pulse signal in step S120 includes a first pulse signal, a second pulse signal and a third pulse signal.
And S120, after the simulation board card of the valve module performs simulation judgment on the running state of the valve plate, feeding back a trigger pulse signal to the valve control system. The valve module simulation board card can simulate the functions of monitoring and bed triggering of the TVM board, and can send pulses with three different pulse widths to the valve control system through the optical fiber input and output board card to completely simulate the return inspection signals of the TVM board for feeding back the state of the valve block.
Specifically, according to the voltage information of the valve plate, when the voltage information of the valve plate is detected to be reverse voltage, whether the valve plate is in a turn-off state is judged; and if so, sending the first pulse signal to the valve control system.
Specifically, when the voltage information of the valve plate is detected to be a forward voltage, whether the valve plate meets a preset conduction requirement is judged; if so, sending the second pulse signal to the valve control system;
specifically, when the voltage information of the valve plate is detected to be a forward voltage larger than the preset electrical parameter, the preset conduction requirement is met, and the valve plate is in a turn-off state, the third pulse signal is sent to the valve control system.
The conduction requirement is a preset value of forward voltage, and when the forward voltage of the valve plate is detected to be larger than the preset value, the valve plate can be judged to be switched on. The first pulse signal is generated after the valve sheet is judged to be in the turn-off state, the second pulse signal is generated after the valve sheet is judged to be capable of being turned on, and the third pulse signal is generated after the valve sheet is judged to be turned on due to overvoltage protection.
For example, by monitoring the reverse voltage on the valve plate, it is determined whether the thyristor valve plate has been turned off. If it has been switched off, a pulse of duration 2us (i.e. the first pulse signal) is sent to the valve control system. Whether the silicon controlled valve plate can be opened or not is judged by monitoring the forward voltage, and if the silicon controlled valve plate can be opened, a pulse of 6us (namely a second pulse signal) is sent to the valve control system. Whether the silicon controlled valve plate which is not turned on but is turned on due to overvoltage protection is judged by monitoring the higher forward voltage. If so, a pulse of 12us duration (i.e., a third pulse signal) is sent to the valve control system.
Further, when the valve control system receives the first pulse signal and the third pulse signal, a fourth pulse signal is generated and sent to the valve module simulation board card, so that the valve module simulation board card determines that the converter station is currently in a recovery period after being turned off.
It can be understood that the valve module analog board card can simulate a backup trigger function of an RPU (recovery period protection unit) board, and can receive, analyze and execute an instruction sent by the valve control system, for example, during a shutdown period, the valve control system sends a pulse (i.e., a fourth pulse signal) with a duration of 1.3ms, and the valve module analog board card receives the pulse and confirms that the pulse is in a recovery period after the thyristor is turned off at this time.
Furthermore, the valve module simulation board card can also simulate the function of an MSC, can receive, analyze and execute a trigger signal sent by the valve control system, and can feed back an optical emission monitoring signal to the valve control system.
Preferably, the signal acquisition device obtains a signal to be monitored according to the received first running state, the received first simulation running information, the received first trigger pulse signal and the received fourth pulse signal; the second operation state is generated by the working state of a converter station in the direct current transmission system, the second analog operation signal is generated by the digital real-time simulation device after simulating the second operation state, the second trigger pulse signal is generated by a bridge arm analog board card after judging the second operation state, and the fourth pulse signal is generated by the valve control system after responding to the first trigger pulse signal and the third pulse signal;
the signal acquisition device sends the signal to be monitored to a wave recording device for wave recording analysis processing to obtain a processed signal to be monitored, and sends the processed signal to be monitored to the monitoring host;
and the monitoring host monitors the direct current power transmission system according to the processed signal to be monitored. The wave recording device can record related signals of the valve control device, related signals sent by the RTDS and related polar control signals and has a wave recording analysis function. The collected operating data includes fault signals of the valve module, ac system voltage, dc unlock lock signal, trigger pulse signal, etc.

responding to the test signal, judging a second running state of a valve plate of a converter station in the direct current transmission system according to second simulation running information sent by the digital real-time simulator, and generating a second trigger pulse signal;

And the second analog operation information is voltage information generated after the digital real-time simulator carries out analog detection according to the received second operation state. The second trigger pulse signal is a trigger signal generated after the bridge arm simulation board card processes the second simulation operation information, and is used for feeding back the operation state of the bridge arm to the valve control system.
