SCD (Substation Configuration Description) precise decoupling method aiming at single equipment replacement

Abstract

The invention provides an SCD (Substation Configuration Description) precise decoupling method aiming at single equipment replacement. The method comprises the steps of S1 acquiring SCD and SPCD files of a transformer substation, and SCD information and SPCD information of replacement equipment; S2 constructing a physical link network topology taking the replacement equipment Unit as a center, and forming a set R by the equipment Units which are away from the replacement equipment by one Cable; S3 establishing a mapping relationship between the IED in the SCD and the Unit in the SPCD to obtain an IED set M of the set R mapped in the SCD file; S4 performing decoupling by taking the IED set M in the SCD file as a decoupling boundary to obtain a related equipment configuration file RCD and a non-related equipment configuration file URCD; S5 returning the decoupled RCD file to a construction party, and locking the URCD file to prohibit modification at the same time; S6 enabling the construction party to modify, debug and verify the RCD file; and S7 taking the set M as a boundary, and combining the URCD file with the debugged and verified RCD file to obtain a brand new SCD. According to the invention, the modification risk caused by SCD modification can be reduced.

Description

technical field [0001] The invention relates to the technical field of grid operation and maintenance, in particular to an SCD precise decoupling method for single device replacement. Background technique [0002] It is difficult to accurately define the scope of the upgrade of the SCD file during the reconstruction and expansion of the smart substation. In order to ensure reliability, the scope of debugging is often increased, and the SCD file of the entire station needs to be modified for the expansion of an interval or even the replacement of one device. Every time the SCD file is modified, all configuration information contained in the SCD needs to be re-verified, which greatly increases the workload of smart substation debugging and operation and maintenance. [0003] In recent years, a method has been developed to generate sub-files after decoupling the SCD file. When carrying out reconstruction and expansion projects, only the sub-files are modified in a targeted mann...

[0011] (3) According to the topological relationship structure of primary and secondary equipment, there is no specific technical solution for single equipment replacement in the secondary system of smart substation. This method still stays at the level of logical relationship for decoupling, and its application range is limited, such as switches, faults The wave recording acquisition unit, or network analyzer acquisition unit and other acquisition and aggregation equipment replacement, there is no effective countermeasure
