By importing the MMS simulation record file, the master station record file and the monitoring background record file, the uniqueness and consistency of the SOE time stamp in the three files are associated, and then the remote signaling in the dispatching information table, the Ref of the SCD and the corresponding relationship described by the monitoring background are formed by importing the dispatching information table, and the corresponding information of the transformer substation in the master station description or the dispatching information table is compared through the monitoring background information description as a third party, then it is automatically judged whether the forwarding configuration is correct, if there is no corresponding information of the transformer substation or the master station description is inconsistent with the monitoring background description, then the manual judgment is relied on to check whether the remote configuration is misaligned, misconfigured or over-configured;

[0011] Remote measurement automatic association and checking, remote measurement data usually do not have SOE time, and cannot be associated by the uniqueness of the time stamp, for this case, the one-to-one correspondence relationship through the remote machine forwarding is determined to obtain the correspondence relationship between the remote measurement and the SCD. According to the formula: "MMS information sending time < receiving SOE time < (MMS information sending time + fixed time interval)", the correspondence relationship between the MMS signal point and the master station point number is determined, and the coefficient can be calculated through the sending value of the MMS and the forwarding value of the remote machine, and then compared with the PT / CT variable ratio in the point table (the configuration exists in the dispatching information table), to check whether the parameter configuration is correct; the monitoring background cannot export the remote measurement value information, and the manual judgment is needed through the master station description and the SCD description to determine whether the remote configuration is correct;

[0013] The debugging device accesses the simulation protection and measurement and control device on the inlet side of the remote machine, which cooperates with the master station automatic acceptance module to complete the joint acceptance of the master and substation monitoring information channel by channel. Only the points that pass the synchronous acceptance can enter the joint acceptance link. The automatic acceptance rules of the master and substation are as follows: the remote signaling points of the substation automatically send the action and reset signals to the master station in the specified interval (such as 100 ms) according to the point table, and the action and reset sequence cannot be reversed. The master station automatic acceptance module also verifies in order from small to large according to the point table, and the value must have action and reset. The remote measurement points of the substation are sent in the specified interval (such as 200 ms) according to the point table, and the remote measurement value is sent according to the point number + 0.99 (offset).

Claims

1. A commissioning device for a substation, characterized in that, Its structure includes a debugging device connected to a remote control communication gateway, which is connected to the dispatch master station through the dispatch data network; The debugging method is to configure and verify the remote signaling, simulate the MMS communication of all secondary intelligent devices in the whole station, send all MMS remote signaling data of the device to the remote motor and the monitoring background through panoramic information scanning, ensure the uniqueness of SOE timestamp, and at the same time simulate the master station to receive the IEC104 remote signaling data forwarded by the remote motor. The sent MMS data forms a simulation log file. The simulation master station forms a master station log file by receiving IEC104 remote signaling forwarding data. The remote signaling data is exported from the monitoring backend to form a monitoring backend log file. Import the MMS simulation log file, master station log file, and monitoring backend log file. By verifying the uniqueness and consistency of the SOE time stamp in the three files, the data of the three files are associated. Then, by importing the control information table, the correspondence between the remote signaling and SCD Ref in the control information table and the description in the monitoring backend is formed. By comparing the information description in the monitoring backend with the corresponding information of the substation in the master station description or the control information table, the forwarding configuration is automatically determined to be correct. If there is no corresponding information of the substation or the master station description is inconsistent with the monitoring backend description, manual judgment is required to check whether there are misconfigurations, omissions, or excess configurations in the remote control configuration. Automatic telemetry association and verification: Telemetry data usually does not have SOE time and cannot be associated with data through time stamp uniqueness. In this case, a one-to-one correspondence is determined through the telemetry relay to obtain the correspondence between telemetry and SCD. The correspondence between MMS signal points and master station numbers is determined using the formula: "MMS information transmission time < SOE reception time < (MMS information transmission time + fixed time interval)". Simultaneously, the coefficient can be calculated using the MMS transmission value and the telemetry unit's forwarding value, and then compared with the PT / CT ratio in the point table to check the correctness of the parameter configuration. Since the monitoring backend cannot export telemetry information, manual verification of the telemetry configuration is required using the master station description and SCD description. During the synchronous acceptance test, the device is connected to the remote control output side as a simulated master station. On-site commissioning personnel conduct background signal acceptance by actually triggering remote signaling or applying remote measurement. The background acceptance personnel compare the consistency of the background screen, the point device screen, and the on-site applied signal, and confirm the signal is correct within a limited time. The debugging device is connected to the simulation protection and control device on the inlet side of the remote control unit. It works with the main station automatic acceptance module to complete the joint acceptance of the main and substation monitoring information channel by channel. Only points that pass the synchronous acceptance can enter the joint acceptance stage. The main and substation automatic acceptance rules are as follows: the remote signaling points of the substation automatically send action and reset signals to the main station at specified intervals according to the point table. The order of action and reset cannot be reversed. The main station automatic acceptance module also accepts the points in ascending order according to the point table, and the values ​​must have action and reset. The telemetry points of the substation send the telemetry values ​​at specified intervals according to the point table, and the telemetry values ​​are sent according to the point number + 0.99 offset. The main station automatic acceptance module also parses the values ​​according to the point number + 0.99, and determines whether the point number and value correspond to each other, and judges whether the sending point is correct.

2. An automatic point-to-point method for a substation verification device, used in the substation commissioning device as described in claim 1, characterized in that, The configuration is associated and verified. Using SCD as the standard, the virtual connection between the intelligent terminal and the measurement and control and protection devices is parsed out, and the process layer connection relationship configuration is generated. At the same time, the station control layer configuration MMS of the measurement and control is parsed out. The high-speed and high-precision debugging device simulates the intelligent terminal to automatically generate GOOSE signals according to the connection relationship and send them to the measurement and control device. The measurement and control device forwards the MMS data to the station control layer. The debugging device simulates the background monitoring to receive the MMS data of the station control layer. The time of the intelligent terminal generating GOOSE event information and the event time of the MMS data are used as unique identifiers. That is, from the time, path, name, and value of GOOSE, the time, path REF, name, and value of MMS, the time of GOOSE and the time of MMS are consistent, the GOOSE name, path, MMS name, path REF can be associated, thereby achieving automatic association of GOOSE and MMS configuration. The background monitoring system automatically aligns the data points. Based on the pre-configured GOOSE and MMS data, the debugging device automatically simulates a smart terminal and sequentially sends GOOSE data to the measurement and control system, which automatically records the sent GOOSE data. The measurement and control system then forwards the MMS data to the station control layer. The background monitoring system receives the data from the station control layer, forming historical event information. The debugging device automatically reads the historical records through the interface with the background monitoring system or via USB flash drive, and automatically compares the event names in the background monitoring history with the pre-configured MMS names to determine whether there are any mismatches or omissions in the background monitoring system, thus achieving the purpose of automatic alignment of the background monitoring system.
