Automatic data point alignment system and method suitable for multiple links of transformer substation

Abstract

The invention discloses an automatic data point alignment system and method suitable for multiple links of a transformer substation. An analog signal sending device triggers a signal and uploads the signal to a master station; the telecontrol information automatic calling and checking module actively calls the telecontrol information to a master station and performs name consistency and point number uniqueness checking to complete basic checking of the telecontrol information of each link; the message interaction module constructs a special automatic point-to-point message channel between the front end and the background of the main station, and sends change data which is uploaded and marked with acceptance marks of each channel of the transformer substation to the background automatic point-to-point module through the special message channel; and the automatic point alignment module performs caching, filtering, sorting and rule judgment on the received to-be-checked data according to whether the received to-be-checked data has an acceptance mark or not, so that the dynamic comparison function of the change data uploaded by the transformer substation is realized. The method has the advantages of being short in project implementation period, low in manpower cooperation requirement, small in influence on an in-operation system, low in transformation difficulty, high in monitoring acceptance efficiency and the like.

Description

technical field

[0001] The invention belongs to the field of power system operation and automation, and in particular relates to a data automatic point-to-point system and method suitable for multi-link substations. Background technique

[0002] The real-time interactive data between the substation and the control master station is the main data source for the application of the control integration function, which requires timeliness, accuracy and reliability. Newly built, rebuilt and expanded substations need to go through strict information acceptance and verification links when they are connected to the power grid. With the continuous deepening of the large-scale operation system, the number of new (renovated and expanded) substations continues to increase, and a large amount of monitoring information is connected to the dispatching control system. The inspection and acceptance work is concentrated and time-consuming, which is likely to affect the scheduled operation of th...
