A design method of virtual terminal configuration table

Abstract

The invention relates to the field of virtual terminal design of an intelligent substation system, in particular to a method for designing a virtual terminal configuration table. Based on each smart device, regardless of the connection relationship of other smart devices, according to the IEC61850 or DLT860 specification, assign the logical circuit number to the virtual terminal that needs to be connected; for the smart terminals within the same interval, line protection, line Measurement and control assignment, complete the virtual terminal configuration table; according to the virtual terminal configuration table, query the virtual terminals with the same "logic circuit number" according to the interrelationship of the smart devices in the interval to connect, and at the same time open the virtual terminals according to the same smart device. Unable to connect, constraints on the connection of the input and output virtual terminals between different smart devices, complete the configuration of the SCD file; avoid repeatedly querying the required virtual terminals among the massive virtual terminals of the two smart devices during the design process. In the process of debugging and operation and maintenance, it is free from the constraints of the virtual terminal production software provided by the integrator, and reduces the workload of designers.

Description

technical field [0001] The invention relates to the field of virtual terminal design of an intelligent substation system, in particular to a method for designing a virtual terminal configuration table. Background technique [0002] According to the development of the power system, the construction of the smart grid starts from the smart substation. The biggest difference from the traditional substation is that the virtual terminal design is added to the smart substation. [0003] In recent years, software designed for virtual terminals has emerged in an endless stream, but the design principle is to find the corresponding virtual terminal from the output virtual terminal and input virtual terminal of two smart devices that are connected to each other for connection. However, there are a large number of virtual terminals, and it is necessary to repeatedly inquire between two smart devices during the inquiry process, which is likely to cause wrong connections, and repeated in...

Problems solved by technology

However, there are a large number of virtual terminals. During the query process, it is necessary to repeatedly query between two smart devices, which is likely to cause wrong connections, and repeated queries make the work efficiency not high.

The SCD file formed after the virtual terminal is produced is a report file for the opening and entering of smart devices, making it impossible to intuitively or concisely query which virtual terminals are opened and connected to in the later stage of debugging and operation and maintenance. smart device
