Configuration file management and control method suitable for expansion and commissioning of bus differential protection in smart substations

Abstract

Disclosed is a configuration file management and control method applicable to busbar differential protection extension and debugging of an intelligent substation. The configuration file management andcontrol method comprises the steps of performing analysis on a busbar differential protection CID configuration file, and generating CRC sub check codes and a total CRC check code at bus intervals from the busbar differential protection process level configuration information; performing busbar protection extension and debugging and updating the CID configuration file; generating the CRC sub check codes and the total CRC check code at intervals; and judging whether the operating and intervallic CRC sub check codes are consistent or not. The configuration file management and control method applicable to busbar differential protection extension and debugging of the intelligent substation provided by the invention has the beneficial effects as follows: it is ensured that the management and control configuration parameters can be identified automatically in the busbar differential protection extension and debugging process; through the software verification mode, it is ensured that an extended interval does not cause influence to the intervals which are already input into operation, thereby ensuring that an outlet transmission test is not needed for the operating intervals after the extended interval is connected, avoiding short-time power down, and improving debugging working efficiency and power supply reliability.

Description

technical field [0001] The invention belongs to the technical field of intelligent substations, and in particular relates to a configuration file management and control method suitable for expansion and commissioning of bus differential protection in intelligent substations. Background technique [0002] The smart substation uses optical fiber to replace the control cable in the conventional substation, realizes the digital communication of process layer information, and overcomes the shortcomings of conventional substation process layer information, such as difficulty in sharing process layer information, complicated control cable wiring, equipment interoperability and poor system scalability. In recent years, smart substations have entered the stage of comprehensive promotion and application from partial demonstration construction, and their communication technology and equipment manufacturing standards have also been continuously developed and improved in the event.

Problems solved by technology

Although this method is convenient for maintaining the SCD model of the whole station, for the expansion and commissioning of bus differential protection across bays, it is impossible to distinguish the configuration file of bus differential protection in each outgoing line interval after it has been confirmed that the configuration file of bus differential protection has changed Therefore, it is difficult to guarantee the accuracy and reliability of debugging
