Description
Technical Field
The invention relates to the technical field of power grids, in particular to an automatic modeling method of a protection device fixed value calculation model based on an ICD file, electronic equipment and a non-transitory computer readable storage medium.
Background
Along with the continuous expansion of the power grid scale, the task of programming the relay protection setting responsibility daily fixed value calculation and fixed value list is becoming heavy, and the accurate and standard device fixed value and fixed value list thereof are the basis for guaranteeing the normal operation of the field device and the basis for guaranteeing the stable operation of the power grid; abnormal or erroneous protector settings will affect the normal and reliable power supply of the grid to the user, even damage equipment, damage grid security, etc. Therefore, the quick and accurate establishment of the relay protection device calculation model relates to the safe and stable operation of the whole power grid.
Along with the continuous construction of intelligent equipment and an intelligent system of the power grid, each professional work of the power grid is changed towards informatization and automation directions. For realizing rapid and accurate modeling of the protection device fixed value calculation model, the professional in the industry designs a protection device custom modeling function and a protection device template association modeling function based on a setting calculation system. The protection device self-defining modeling function is used for manually defining one-by-one constant value item through manually analyzing a printing list of the protection device, so that a complete protection device model is formed.
According to the modeling method, a person checks the calculation logic of the constant value items one by one, knowledge accumulation is formed by taking a protection device model as a unit, and a primary model is built for the same device model. Because a new method for rapidly improving modeling efficiency is difficult to find from the self-defining direction of the constant value item, how to automatically establish the constant value item of the device needs to be considered in combination with the construction of the current intelligent station and intelligent equipment. For this purpose, it is proposed to build a device-value commonality in the system, build a generic tuning assembly, a specific tuning assembly, and form a new protection device model by a combination of the respective assemblies, while device modeling by this method still requires building a basic value item list by which to correlate with the device-value commonality, forming a device model and tuning assembly correlation, ultimately forming a device-value calculation model. Although the process of self-defining and maintaining the calculation formula of the constant value items is simplified to a certain extent, the association process of the device constant value item list still needs a great deal of manual intervention, the association process cannot be combined with intelligent system data, and the human risk is large. When the field fixed value demand is large and the new production equipment is more, the efficiency and quality of model generation cannot be obviously improved by a method for forming a device fixed value calculation model through a large number of manual definitions or manual association, and the mode defect that model maintenance is carried out by a large number of manual works is more remarkable along with replacement of protection professionals. Under the continuous promotion of informatization and digital construction of relay protection data, a basic calculation model adopts any manual processing mode, which does not meet the technical progress and the information intelligent construction requirement of scheduling; moreover, the device model of the existing setting system is difficult to be associated with the intelligent system of the transformer substation, so that the system is isolated in application; an automatic modeling method for a fixed value calculation model of a protection device, which is automatic and can realize knowledge and experience accumulation, is needed to make up for the defects and defects of intelligent construction of the current protection professional application system and lay a foundation for the construction of a comprehensive and complete relay protection professional informatization system.
