In this embodiment, the data simulator obtains a preset SCD file (substation configuration description, i.e., a substation configuration description file) of the substation, and generates a CID file (configured IED description, i.e., a configured intelligent device description file) of the IEC61850 device through the SCD configuration tool, as a model file of a device such as protection, measurement and control, and online monitoring; and acquiring a CFG-1 file (full configuration file of a real-time dynamic monitoring system of the power system) from the PMU device, analyzing phasors, analog quantities and switching quantities, configuring communication parameters such as communication identifiers, IP addresses, TCP port numbers and the like, and taking the communication parameters as an IEEE1344 model file of the PMU device. It should be noted that, the data simulation device needs to acquire a system configuration file before the configuration file of the spacer layer device is configured according to actual requirements, and after the data simulation device for testing the station-controlled layer device installs the system configuration file, the data simulation device detects the generation of a new configuration and automatically starts the simulation of various service data according to the new configuration.

202. Configuring CID model files and MMS communication protocols for the protection equipment, the measurement and control equipment and the online monitoring equipment, configuring IEEE1344 model files and IEEE1344 protocols for the PMU device, enabling the protection equipment, the measurement and control equipment and the online monitoring equipment to execute MMS communication tasks corresponding to the MMS communication protocols under the preset first change rules, and enabling the PMU device to execute IEEE1344 communication tasks corresponding to the IEEE1344 protocols under the preset second change rules;

In this embodiment, the data simulation device configures model files and communication protocols for devices of different service types, wherein devices such as protection, measurement and control, on-line monitoring and the like select CID files and MMS communication protocols, and the PMU device selects IEEE1344 model files and IEEE1344 protocols; meanwhile, automatic change rules such as starting delay, telemetry range, telemetry change step length, telemetry period, telemetry signal change period, disturbance data generation period and the like are set.

203. And acquiring data simulation result messages sent by the protection equipment, the measurement and control equipment, the on-line monitoring equipment and the PMU device after executing communication tasks, analyzing the data simulation result messages to obtain data simulation results and displaying the data simulation results.

The data simulation device firstly executes task scheduling, constructs spacer layer simulation equipment according to a system configuration file, then schedules corresponding communication tasks according to a communication protocol associated with the spacer layer simulation equipment, waits for each communication task to finish initializing the device, finally manages periodic changes of all telemetry, remote signaling and disturbance data in a transformer substation according to an automatic change rule of the data, and receives a temporary burst change rule triggered by a human-computer interface to generate a specified number of telemetry, remote signaling and disturbance data in a specified time.

The process of executing the communication tasks by the protection equipment, the measurement and control equipment and the on-line monitoring equipment is as follows: each simulated protection, measurement and control, on-line monitoring and other devices start an independent MMS communication task. After receiving the transferred model file and the starting delay, the MMS communication task analyzes the CID model according to IEC61850 application model specification, establishes a complete analog device database according to remote signaling, telemetry, protection event, fixed value and other data contained in the dataset in each LD (logic device), instantiates the analog device according to IEDname (intelligent electronic device name intelligent electronic equipment name) and IP address, then starts link communication after the starting delay is reached, and establishes a communication model containing the following services: the system comprises an association service, a data read-write service, a report service, a control service, a fixed value service and a file service. And the MMS communication task monitors signals in a database of the device, and when telemetry, remote signaling and protection events change, the report service is adopted to send the station control layer equipment. The MMS communication task receives the remote control command of the to-be-tested station control layer equipment, and changes the position state of the switch after the command is successfully executed. And the MMS communication task receives commands such as fixed value inquiry and modification of the to-be-tested station control layer equipment, and the modified fixed value is stored in the database. After the MMS communication task monitors the Comtrade file generated by the disturbance data, the Comtrade wave-recording file is sent to the to-be-tested station control layer equipment through the file service.

The PMU device performs the following communication tasks: each simulated PMU device initiates a separate IEEE1344 communication task. After receiving the transferred model file and the starting delay, the IEEE1344 communication task establishes a complete device database according to phasors, analog quantity and switching value, instantiates the analog device according to the communication identifier, IP address and TCP port number, and then starts the link communication after the starting delay is reached. The IEEE1344 communication task supports CFG-1 frame transmission and CFG-2 frame configuration, and real-time data such as phasors, analog quantities, switching quantities and the like are periodically transmitted according to the configured transmission rate. The IEEE1344 communication task receives a calling file directory and dynamic and transient file commands issued by the to-be-tested station control layer equipment, and responds to files in the file directory corresponding to the simulation device.

The data simulation device monitors communication of the to-be-tested station control layer equipment in real time from two layers, namely monitors received messages of a bottom layer interface, and analyzes the messages from a communication task application layer. Specifically, all data frames on the local network card are received by creating an original socket, a BPF filter is set to screen TCP data packets conforming to MMS and IEEE1344 application ports, the received data packets are cached in a memory pool, then a special task is created to take out the data packets from the memory pool, the starting time is the file name and the data packets are stored as files, and the files are used for subsequent data simulation result message analysis.

At the application level of the communication task, after analyzing the data simulation result message, the obtained data simulation result comprises: when the to-be-tested station control layer equipment establishes a link or breaks the link, generating event records (including time, source address and other information); monitoring a remote control command, and generating an operation record (including information such as time, source address, switching command state and the like); monitoring a constant value modification command to generate an operation record (including information such as time, source address and the like); monitoring disturbance data file calling command, generating operation record (including time, source address, file name and other information); the number of communication tasks accumulation generation events and transmission events is counted.

The data simulation device displays the data simulation result through the display screen so as to be checked by monitoring staff.

The embodiment of the invention can flexibly simulate the characteristic data of multiple service types aiming at the to-be-tested station control layer equipment, realize the simulation of the substation spacer layer equipment on the reported message, realize the centralized concurrent simulation of the type data such as protection, measurement and control, on-line monitoring, PMU and the like, finish the inspection of the intelligent remote control gateway and other centralized station control layer equipment, and can carry out on-line monitoring of communication messages and automatically identify errors in the message interaction process, thereby providing great convenience for the test personnel to carry out message analysis.

The following is an application scenario of a data simulation method for testing substation control layer equipment of a transformer substation:

The data simulation device can flexibly configure the quantity and the types of the spacer layer equipment, and can simulate 256 spacer layer equipment at most. The data simulation device simulates the simultaneous starting or sequential starting process of all devices by setting the starting delay parameters of the devices; the states of all signals are periodically changed by setting the change periods of telemetry and remote signaling, so that a state change message is sent, and communication flow control is carried out; simulating protection action behaviors by setting protection events and disturbance data generation periods; the appointed signal of the appointed device is selected through the human-computer interface to generate a certain number of changes in the appointed time, so that the simulation of system faults and avalanche business is realized.
