It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.

Example 1
Fig. 2 is a flow chart of a method for checking a relay protection setting value according to a first embodiment of the present invention, where the method may be implemented by a relay protection setting value checking device, and the device may be implemented in a software and/or hardware manner. The device can be configured in a terminal device/a server, and the method specifically comprises the following steps:
s110, acquiring a fixed value list to be checked, and determining the relay protection equipment category to which the fixed value in the fixed value list belongs;
in the power system, relay protection devices may be classified into different types of protection, including line protection, transformer protection, capacitor protection, motor protection, and the like. The relay protection devices of different types have different fixed values correspondingly, and due to different requirements in the power system, such as environment temperature, circuit load and the like, the same relay protection devices can also have different fixed values, and in the power system, the relay protection devices can automatically cut off fault devices in the shortest time and the smallest area, so that the influence of the fault devices on power supply of adjacent areas is reduced or avoided. However, after long-time operation, the relay protection equipment is aged and the failure condition of the parts is serious, and operators need to regularly perform relay protection test and maintenance work.
The fixed value list is a list formed by fixed values stored in a relay protection operation and maintenance management and control system needing to be checked, wherein the fixed values are different in type and can belong to a plurality of relay protection devices of a plurality of types or one relay protection device, and the fixed values can be numbers or characters, such as 100v, 55hz and 0X3FFF.
Specifically, a fixed value management function of the relay protection operation and maintenance management system can be used for selecting fixed values of relay protection equipment to be checked from fixed values stored in the system to generate a fixed value list, wherein the fixed value list comprises the device model, interval and station of the relay protection equipment to which the fixed values belong. Preferably, the relay protection equipment category corresponding to the fixed value can be determined according to the device model and the interval in the fixed value list.
S120, determining a target relay protection standard model corresponding to the constant value list from candidate relay protection standard models belonging to the relay protection equipment category;
the relay protection equipment standard model can be a calculation model for generating a model meeting the requirements of an electric power system, the model can be built in a CPU of the relay protection equipment, and the relay protection equipment standard model can also be an information model for defining a constant value generation principle.
In a power system, different classes of relay protection devices have different relay protection standard models, such as line protection, transformer protection, capacitor protection, or motor protection. For similar relay protection devices, there are also different requirements in the power system, for example, requirements of system parameters, configuration of protection functions, coordination of action values and time between different protection functions, etc., the similar relay protection usually has one or more relay protection standard models of principle, which are used for generating one or more sets of protection fixed values suitable for the present protection device, and under different standards, the values of the same fixed value item of the relay protection device of the same device model may be different.
After determining the type of relay protection equipment to which the fixed value in the fixed value list belongs, it is not clear what principle of the relay protection equipment the fixed value in the fixed value list is generated based on, and therefore, the fixed value list cannot be directly used for checking whether the fixed value list meets the requirement of the power system.
Specifically, a fixed value item in a plurality of relay protection standard models belonging to the same kind of products can be analyzed by using a fixed value management function of a relay protection operation and maintenance management and control system and utilizing fuzzy recognition and intelligent matching technologies, so that a relevant target relay protection standard model related to the fixed value in the fixed value list is determined. For example, multiple sets of fixed values under corresponding models can be generated according to relay protection standard models of similar products, association analysis is performed on the fixed values in a fixed value list to be checked, and a target relay protection standard model corresponding to the fixed value list is determined.
S130, determining a fixed value sequence number and a fixed value name of a fixed value in the fixed value list based on the target relay protection standard model;
s140, determining relay protection equipment to be checked according to the fixed value list;
the fixed value serial number may refer to a number allocated to the fixed value in all fixed values owned by the relay protection device, the fixed value name may refer to a protection function name of the fixed value in the relay protection device, and the relay protection device to be checked may be the relay protection device to which the fixed value in the fixed value list belongs.
In general, a relay protection device has various constant protection functions, for example, a short-circuiting device may have overload protection trip current, short-circuit protection trip current, rated limit short-circuit breaking, rated operation short-circuit breaking, and the like. A relay protection standard model may have a constant value data set, for example, a constant value data set composed of a number 001, a name protection switching control word, a constant value 0X3FFF, a number 009, a name low-pressure separation section I constant value, a constant value 100v, a number 020, a name Zhou Qieji one round constant value, and a constant value 55hz may be provided.
Therefore, after the target relay protection standard model is determined, the fixed value sequence number and the fixed value name of the fixed value in the fixed value list can be determined based on the target relay protection standard model. For example, a mapping relationship between the fixed value serial number and the fixed value name of the relay protection device and the fixed value in the fixed value list may be established. After the mapping relation is established, the serial number, the name and the affiliated fixed relay protection equipment of the fixed value to be checked can be obtained
In the prior art, after a fixed value list to be checked is obtained, a fixed value management function of a relay protection operation and maintenance management system can also obtain a fixed value serial number, a fixed value name and relay protection equipment to which the fixed value belongs, and remotely retrieve the fixed value of the relay protection equipment of each station, but due to the lack of support of an informatization integration platform, each functional module is in an information island state and lack of collaboration, the station, the interval and the device are manually and generally checked one by one to determine whether the relay protection equipment and the relay protection standard model of the operation of the relay protection equipment, the communication state, the operation state and the like of the relay protection equipment exist, and the information and the service provided by each system are difficult to adapt and correctly used by staff, so that the operation and maintenance efficiency of each information system is not only not improved, the workload of operation and maintenance staff is increased, and the operation and maintenance cost is improved.
According to the technical scheme, the method and the device are matched with the existing relay protection equipment standing book, and the relay protection equipment to which the fixed value in the fixed value list belongs is determined, namely the relay protection equipment to be checked in the task.

Optionally, the determining, according to the fixed value list, the relay protection device to be checked includes:
and if the station, the interval and the device model in the fixed value list are consistent with the equipment account record of the station, the relay protection equipment in the station is used as the relay protection equipment to be checked.
For example, the system equipment ledger management function module can be utilized to comb the ledger record of each station to check the device model and the interval of the relay protection equipment actually adopted by each station, and the device model and the interval of the relay protection equipment are compared with the fixed value list to determine the specific station and the specific relay protection equipment to be checked. Furthermore, the station accounts of all stations of the woolen station can be used for checking the relay protection standard model and the communication state of the relay protection equipment which are actually adopted.
And S150, performing fixed value checking on the relay protection equipment according to the fixed value serial number and the fixed value name.
Specifically, after the relay protection device is determined, the fixed value serial number and the fixed value name to be checked can be checked based on the target relay protection standard model used by the relay protection device. It may be first determined whether the value to be checked is within a constant value patrol period, the constant value within the period is reserved, and the constant value outside the period is recalled.

Optionally, based on the above technical solution, step S150 may preferably perform verification according to the communication state and the operation state of the relay protection device that needs to be verified.
Preferably, it may include:
determining a constant value inspection period of the relay protection equipment;
under the condition that the relay protection equipment is in an operation state, if the fixed value is detected to be in the inspection period, the fixed value in the inspection period is taken as an effective fixed value; otherwise, calling the fixed value to obtain an effective fixed value;
