A data automatic point-to-point system and method suitable for substation multi-link

Abstract

The invention discloses a data automatic point-to-point system and method suitable for multi-link substations. The trigger signal of the simulated sending device is sent to the master station; the telecontrol information automatic calling and checking module actively calls the telecontrol information to the master station , and check the name consistency and point number uniqueness, and complete the basic check of the telecontrol information of each link; the message interaction module builds a dedicated automatic point-to-point message channel between the front and back of the master station, and sends The changed data sent from each channel of the substation and marked with the acceptance mark is sent to the background automatic point-to-point module; the automatic point-to-point module caches, filters, sorts and judges the received data to be inspected according to whether it has the acceptance mark, so as to realize the transmission of the substation Change data dynamic comparison function. The invention has the advantages of short project implementation period, low manpower coordination requirements, little impact on the operating system, low modification difficulty, high monitoring and 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...
