Embodiment 1

[0063] The technical invention of fixed value standardization involves the design rules of the key fixed value standard library and the realization method of automatic matching of different system fixed values. The detailed technical scheme is as follows:

[0064] (1) Design of key fixed value standard library

[0065] The key fixed value standard library is designed for the fixed values ​​that need to be checked and optimized, that is, it does not include various control words, pressure plates, basic parameters and other fixed values ​​that do not need to be calculated and checked. It is mainly based on the characteristics of the device type, the type of the fixed value item, and the name of the specific fixed value item for standardized design. Since the fixed value standard library is oriented to different systems, it is necessary to design a unique identification numbering rule for fixed value items.

[0066] The unique identifier of a fixed value item consists of three p...

Embodiment 2

[0080] In order to make the settings automatically derived by the tuning system directly applied to the on-line calibration system, it is necessary to establish the association between the principle-level settings and device-level settings in the setting calculation and the characteristic settings in the online calibration, and the system needs to automatically The fixed values ​​in the setting system are converted into key fixed values ​​that can be identified by online verification, forming a real-time verification of the fixed value database, and laying a data foundation for the real-time verification of the fixed values. The flow of the fixed value standardization method used for online calibration and offline setting is as follows:

[0081] (1) Design the key fixed value standard library, and establish a one-to-one correspondence between the online check and check set value and the set value derived from the setting system;

[0082] (2) It is designed to store the real-ti...

Embodiment 3

[0087] Based on the same inventive concept, the present invention also provides a fixed value standardization system for online calibration and offline setting, including:

[0088] The automatic matching module is used to automatically match the fixed value items in the online calibration system and the offline tuning system according to the pre-established key fixed value standard library, and form the unique standardized number of the fixed value items in the online calibration system and the offline tuning system ;

[0089] The pre-established standard library of key fixed values ​​includes a numbering rule for the unique identification of fixed value items.

[0090] The numbering rules for unique identification of fixed value items include:

[0091] The unique identifier of a fixed value item consists of three digits; the three digits are:

[0092] The first bit is the device type: identifies the primary device type that the device is oriented to;

[0093] The second di...

Abstract

The invention relates to a fixed value standardization method and system for online checking and offline setting. According to the pre-established key fixed value standard library, the online checking system and the setting items in the offline setting system are automatically matched to form an online The unique standardized number of the fixed value item of the calibration system and the offline setting system; according to the unique standardized number of the fixed value item, the closed-loop control of the online calibration system and the offline setting system is carried out; the pre-established key fixed value standard library includes fixed value The item uniquely identifies the number sequence. The technical solution provided by the invention solves the problems of cumbersome process, heavy workload, error-prone and low data update efficiency in the current fixed-value docking mode; the basic data standardization guarantee and technical support provided by the invention.

Description

technical field [0001] The invention relates to closed-loop management and control of an online calibration system and an offline tuning system and related system research and development technologies, and in particular to a method and system for standardizing values ​​for online calibration and offline tuning. Background technique [0002] As the power grid structure becomes more and more complex and the operation mode is flexible and changeable, as the first line of defense of the power grid, the relay protection device's fixed value information is related to the safe operation of the power grid. In order to improve the accuracy and efficiency of the fixed value calculation, relay The setting of protection setting is mainly completed by the relay protection setting system, and the checking of the setting is done through the setting online checking system to check the real-time operation mode and the "four characteristics" of setting the setting in the expected mode. At pres...
