Description

Technical Field

[0001] The present invention relates to the field of power system automation, and particularly to a method and system for managing substation production information based on big data. Background Art

[0002] With the rapid development of the power industry, the substation, as an essential key link in the power system, the stability and efficiency of its production operation are crucial for ensuring power supply. When facing the increasingly complex power system and diverse management requirements, the traditional substation production information management methods gradually expose many problems.

[0003] In terms of equipment management, the existing technologies manage the primary and secondary equipment of the substation rather dispersedly. The main wiring diagram of primary equipment often only shows the basic equipment connection and operation status, lacking the integration of detailed equipment ledger information, such as manufacturer information, circuit breaker model, commissioning date, etc., resulting in difficulty for operation and maintenance personnel to quickly obtain comprehensive and accurate information when carrying out equipment maintenance and management. The management of secondary equipment also has deficiencies. The ledger information, maintenance records, etc. of each equipment lack systematic integration, and the information interaction between different equipment is difficult, affecting the operation and maintenance efficiency and accuracy.

[0004] In terms of information sharing, the traditional substation production information management systems are independent of each other, and it is difficult to achieve effective data sharing. There is no effective interconnection mechanism among the PMS system, risk control platform, dispatching automation system, etc., resulting in a serious information island phenomenon. For example, during the maintenance operation of primary equipment, relevant equipment information, maintenance records, etc. cannot be synchronized to other associated systems in real time, making the cooperation efficiency between different departments low, and the information transmission is not timely and accurate.

[0005] For the management of the DC system, the existing technologies also have certain limitations. Although it can monitor the basic operation parameters of the DC system, the display of the DC power flow distribution is not intuitive enough, lacking in-depth analysis and mining of the historical data of the DC system. This makes it difficult for operation and maintenance personnel to comprehensively master the operation rules of the DC system, unable to timely discover potential problems and take effective preventive measures, affecting the reliability and stability of the DC system.

[0006] In terms of remote information sharing, when the traditional substation production information management system realizes remote monitoring, there are often security risks. The data lacks effective encryption measures during the transmission process and is easily stolen or tampered with. At the same time, the access control mechanism is not perfect enough to finely manage the access rights of different users, which may lead to the leakage of sensitive data.

[0007] In addition, the existing technology is also insufficient in terms of improving and guaranteeing system functions. The lack of effective information feedback and improvement mechanisms makes it difficult to timely optimize and adjust system functions according to actual usage. The data backup and recovery functions are not powerful enough, and when data is lost or damaged, it is impossible to quickly and effectively restore data, affecting the normal operation of the system. The operation log recording and auditing functions are also not perfect, making it difficult to fully trace and conduct security audits on user operations, and unable to guarantee the compliance and security of system operations.

[0008] To sum up, the existing substation production information management technology can no longer meet the current development needs of the power industry. There is an urgent need for a more efficient, safe and comprehensive substation production information management method and system based on big data to improve the production and operation management level of substations and ensure the stable and reliable operation of the power system.

[0015] The implementation of remote information sharing in step S5 specifically includes the following steps: S51: Build a remote information sharing channel to allow computer users within the system intranet to access the station-side background data system, and achieve remote monitoring of substation equipment information and operation conditions; S52: Add encryption technology during data transmission; S53: Implement an access control mechanism to restrict access rights to sensitive data, and only authorized users can access relevant data.
