Description
Technical Field
The invention relates to an information protection system in an electric power system and an initialization method thereof, belonging to the technical field of electric power systems.
Background
The information protection system in the power system needs to perform initialization operation on newly accessed equipment and device information, and the main function of the system is to directly store the basic information and description information of primary equipment and corresponding secondary equipment (devices) and description information into a database. This operation process consumes a lot of time for engineering personnel to debug each time the station-level equipment is initialized due to different kinds and numbers of equipment. Most systems are initialized for a single device or equipment at the time of initialization, and with the progress of computer software technology, the function of one-key initialization begins to appear, but the effect cannot meet the field requirements of engineering personnel.
Taking the initialization substation as an example, when information of a calling station is called, a group title of the calling station needs to be called first, then calling description and attributes continue according to the difference of the station group titles, commands when the group title is called are different from the commands for calling the description and the attributes, and have a sequence, the group title needs to be called first, then the description and the attributes are called, when aiming at secondary equipment, the group title needs to be called first, and then different calling description and attribute commands are issued according to a cpu number and a group title number. The whole process needs to be carried out according to strict sequence requirements, but because the quantity of primary equipment and secondary equipment under the primary equipment is large, if the primary equipment and the secondary equipment are sequentially carried out, long time is needed for completing the initialization of the substation, and the rapid application of the substation is influenced.

Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
Method embodiment
The invention improves the initialization process of the information protection system in the current power system, mainly improves the initialization efficiency and reduces the initialization time by parallel execution of partial commands in the current initialization process. Specifically, a command is allocated for the initialization of each device, when the devices in the information protection system are initialized, the commands of the devices are controlled to run in parallel, the command of each device comprises a group title for calling the device, and then corresponding description and attribute calling are respectively carried out according to the called group title; when the stations in the information protection system are initialized, the command of each station comprises a group title for calling the station and controlling the parallel operation of the commands of each station, then the calling of corresponding description and attributes is carried out according to the called group title, if the description and the attributes of the station relate to the return of a secondary device, if the description and the attributes of the station relate to the return of the secondary device, the command distributed for the device is called, and the commands are controlled to operate in parallel.
Each command (including the commands of the station and the commands of the device) is stored by adopting a database (such as redis) based on a Key-value type, the Key is a unique ID of the command, the value is stored in a json character string format, and a value storage structure in the Key-value database is shown in fig. 1, wherein cmdList is that all commands are sent; cmdMidList is a command that needs to be polled; cmdRecList is the command that has been returned; srerrorinfo is exception information; sProcessInfo is process information and is stored into data as required; sKey is a unique command identifier; status is a status identifier used to distinguish whether a command returns, succeeds, and fails; veResult is the returned result set list, the content of which is determined by the service. And judging whether the currently called method, parameter, type, time and command are successfully returned or not according to the data change of the List. The command states in the Key-value database are shown in fig. 2.
As shown in fig. 4, the device initialization includes an attribute method for calling a device group header and device description, the device group header initialization, the device group description and the device attribute initialization are all designed as atomic services, each atomic service corresponds to a command, when the device needs to be initialized, the initialization commands of the devices are controlled to run in parallel, and the function of device one-key initialization is to call the device group header first and then call the device description and the device attribute. As shown in fig. 5, the group header of the station is initialized first, and the description and attributes are initialized by returning the group header of the calling station, so that the device initialization function can be called when the return of the secondary device is involved in the description and attributes of the station. When the entire return state is 0, it indicates that the initialization is completed, and the loop nest of the device initialization is involved in the initialization of the station.
As shown in fig. 3, a specific process of initialization is first to determine whether the skey is empty, if the skey is empty, it indicates that the device initialization process starts, a uuid is generated as a key stored in redis, status, cmdList, cmdMidList, and cmdrecl are initialized to json character string as value and stored in redis, then status is set to 1, cmdlest and cmdredlist are set as parameter lists of sent commands, and cmdrecl is set to be empty. And returning the result including the key stored by the redis and the corresponding state status to the client, and when the client judges that the operation is not finished, assigning the key to the skey to serve as an incoming parameter to continue to call the service. When the service is called again, the logic for judging status in redis is entered with skey. If status is 1, judging whether the sizes of cmdlist and cmdRecList are equal, if so, considering that the sent command is returned, setting status to be 0 at the moment, returning, and if not, considering that the command is not returned, and at the moment, not modifying the stored result set and returning; if status is 2, then consider that the command has returned failure information, the command is considered to be completed, remove the current record in cmdMidList, and add a record in cmdRecList; if status is 0, the command is considered to be finished, whether the type of the current command needs to be sent by a sub command or not is judged, if the group of sub commands needs to be sent, the process is called in a nested mode, corresponding records are added into cmdList and cmdMidList in the command, new key-value pairs are stored in redis and correspond to the command records, and if the group of sub commands is not needed, the command is considered to be completely finished.
