Embodiment Construction
[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0034] Such as Figure 1 to Figure 2 As shown, the present invention provides a method for converting a middle point table of a relay protection device, which specifically includes the following steps:
[0035] Comparison and grouping of points in the point table: compare the difference between the corresponding points in the point table of the new and old relay protection devices, and compare the point table of the new relay protection device according to the difference of each point in the new and old relay protection device. The points in are grouped, such as figure 2 As shown, the detailed groupings are:
[0036] No-to-one, refers to the points that are not in the point t...

The invention discloses a method for converting a point table of a relay protection device, which compares the differences of corresponding points in the point table of the old and new relay protection devices, and groups the point tables in the new device according to certain rules according to the difference; Different groups of points establish corresponding mapping logic for each group of points, and save the mapping logic in the relay protection device in the form of a resource configuration file; the resource configuration file is analyzed by the HMI program, and the new device point table and After analysis, the real-time status of the new device is converted into the point table of the old device and the real-time status of the old device; the converted point table is normally sent to the background or telecontrol. By adopting the conversion method of the middle point table of the relay protection device of the present invention, the compatibility of the new generation of relay protection devices can be improved, the direct replacement of the relay protection device in the substation can be realized, and the need to update the background and The problem of remote control, thereby reducing the investment cost of substation relay protection device replacement.
Description
technical field [0001] The invention belongs to the technical field of electric power system relay protection, and in particular relates to a method for converting a midpoint table of a relay protection device. Background technique [0002] As an important guarantee for the stable and reliable operation of the power system, relay protection devices have existed for decades along with the operation of the power system. Each batch of relay protection devices has a certain number of years of reliable operation, usually 15 to 20 years. With the development of the power system, it is necessary to update the relay protection devices that have reached or are close to the service life every time, and the compatibility between the new and old relay protection devices is involved in the process of batch replacement question. [0003] In recent years, relay protection devices have developed rapidly and their functions have been continuously improved, resulting in more and more differ...
