Secondary system data control method covering whole process of intelligent substation

Abstract

The invention relates to a secondary system data control method covering the whole process of an intelligent substation. The flow and control objects of the whole process of an intelligent substation are combed through according to the secondary system data control need of the whole process of the intelligent substation, and the version encoding rules of data are designed. Then, the data and flow are abstracted, and the method is designed and implemented based on a web-based software technology. The method has the advantage that secondary data which must be controlled effectively in the whole process of an intelligent substation is analyzed under needs related to intelligent substation construction and operation to realize automatic management and advance for different people at different stages, artificial error and confusion are reduced, and the efficiency and quality are improved. Moreover, the same configuration files and the versions of the configuration files are calibrated effectively in an efficient, accurate and consistent way based on an intelligent substation construction and maintenance flow, intelligent substation device calibration is facilitated, and the ability of intelligent substation operation and maintenance is improved.

Description

technical field [0001] The invention belongs to the field of smart substations, and in particular relates to a secondary system data management and control method covering the whole process of smart substations, which is specifically applicable to the SCD configuration files of smart substations in the whole cycle of feasibility study, design, construction, commissioning, operation and maintenance, etc. The management and control of various secondary data. Background technique [0002] Smart substations are a key component of smart grids. China has gradually promoted the pilot application of smart substations since 2009, and more than 2,000 substations have been put into operation. The core standard of smart substation is IEC61850 (DL / T860 in China). Since the IEC61850 standard mainly uses network communication and software technology to standardize the secondary system of smart substations, especially the object-oriented technology of software is used to model the function...

Problems solved by technology

However, SCD and CID configuration files are not considered as design materials during the construction of smart substations, and their editing involves multiple roles such as design institutes, integrators, and device manufacturers. There is no complete approval process, and XML-based text modification It is very easy. This has resulted in multiple modifications of the configuration files during the construction and debugging process. There is no unified coordination with each other, and the version is uncontrollable, which leads to certain confusion in the configuration. After the device configuration is completed, it will inevitably bring problems or potential hidden dangers to the system operation. It causes troubles for debugging and post-operation and maintenance work, prolongs the construction period and reduces the quality
