Description

Technical Field

[0001] This invention relates to the field of power communication technology, specifically to a method and system for classifying and protecting the impact of relay protection services on production scheduling. Background Technology

[0002] The power system is a crucial infrastructure supporting economic and social development and ensuring basic livelihoods. The normal operation of modern society heavily relies on a reliable power supply. A large-scale power outage can trigger a chain reaction across various sectors, leading to significant economic and property losses, and even causing social panic and endangering national security. Faults and abnormal operating conditions frequently occur during power system operation. These phenomena can develop into accidents that render the entire system or a part of it unable to function properly, requiring rapid fault isolation within one-tenth of the time limit. s Even faster. This task cannot be completed by humans and requires an automated system. The role of power relay protection is not limited to isolating faulty components and limiting the impact of accidents; it also ensures the safe and stable operation of the entire system. Each protection unit shares system operation and fault information data. Based on the analysis of this information and data, each protection unit and the reclosing device coordinate their actions, achieving networked microcomputer protection devices. In this way, the more system fault information the relay protection device receives, the more accurate its judgment of fault nature, location, and distance detection, greatly improving protection performance and reliability. The existing communication dispatch support system has a low level of informatization and intelligence. It mainly collects, summarizes, and displays configuration data, alarm information, and performance data of various communication devices, but lacks the ability to analyze and process relevant data and provide decision support. This kind of basic work accounts for a large proportion of communication dispatch work, currently relying mainly on manual processing, resulting in high manpower consumption, low efficiency, and weak ability to respond to emergencies. Summary of the Invention

[0003] The purpose of this invention is to provide a method and system for classifying the impact of relay protection services on production scheduling. Based on the status of the protection devices at both ends of the relay protection service, the status of the line to which the relay protection service belongs, and the number of protection device lines, a classification strategy for relay protection service is formulated, thereby reducing the risk of the power system's stable and safe operation being affected by protection device failures or protection line failures.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] This invention provides a method for classifying the protection impact of relay protection services on production scheduling, comprising:

[0006] Obtain the status of the protection devices at both ends of the relay protection service, as well as the status of the line to which the relay protection service belongs;

[0007] Determine the status of relay protection services based on the information obtained;

[0008] Based on the determined relay protection service status and the number of protection device lines, the protection level for the impact of relay protection services on production scheduling is determined.

[0009] Furthermore, the status of the protection devices at both ends of the relay protection service includes commissioning and decommissioning.

[0010] Furthermore, the line status of the relay protection service includes normal, hot standby, cold standby, maintenance, and out of service.

[0011] Furthermore, determining the relay protection service status based on the acquired information includes:

[0012] If the protection devices at both ends of the relay protection service are in operation and the line to which the relay protection service belongs is in normal condition, then the relay protection service is in operation.

[0013] If the protection devices at both ends of the relay protection service are in operation, and the line to which the relay protection service belongs is in any one of hot standby, cold standby, or maintenance status, then the relay protection service status is in operation - can be shut down.

[0014] If the protection device at any end of the relay protection service is in decommissioned status, or the line to which the relay protection service belongs is in out of service status, then the relay protection service status is out of service.

[0015] Furthermore, the method for determining the number of circuit sets for the protection device is as follows:

[0016] If the relay protection service belongs to a single service line, and each of the two ends of the relay protection service has only one protection device, and both protection devices are in operation, then the protection device line is a single set of operation.

[0017] If the relay protection service belongs to two lines, and each of the two ends of the relay protection service has two protection devices, and all four protection devices are in operation, then the protection device line is operating in dual-set mode.

[0018] Furthermore, the determination of the protection level for the impact of relay protection services on production scheduling based on the determined relay protection service status and the number of protection device lines includes:

[0019] If the relay protection service status is "in operation" and the line to which it belongs is a single unit in operation, then the service protection level is extremely high.

[0020] If the relay protection service status is "operating" and the corresponding line is operating with two sets of equipment, then the service protection level is high.

[0021] If the relay protection service status is "operational - outageable" and the line to which it belongs is a single unit in operation, then the service protection level is high.

[0022] If the relay protection service status is "operational - outageable" and the line to which it belongs is operating with two sets of equipment, then the service protection level is medium.

[0023] If the relay protection service status is out of service and the line to which it belongs is operating as a single unit, then the service protection level is low.

[0024] If the relay protection service is out of service and the corresponding line is operating with two sets of equipment, then the service protection level is low.

[0025] Furthermore, the method also includes:

[0026] The status of relay protection services and the level of service assurance are displayed.

[0027] This invention also provides a protection classification system for the impact of relay protection services on production scheduling, which is used for the protection classification method for the impact of relay protection services on production scheduling before implementation. The system includes:

[0028] The data acquisition module is used to acquire the status of the protection devices at both ends of the relay protection service and the status of the line to which the relay protection service belongs;

[0029] The service status analysis and decision module is used to determine the relay protection service status based on the acquired information.

[0030] The protection device circuit count analysis and judgment module is used to determine the number of protection device circuits.

[0031] The protection service assurance classification analysis and decision module is used to determine the assurance level of the impact of relay protection services on production scheduling based on the determined relay protection service status and the number of protection device lines.

[0032] The beneficial effects of this invention are as follows:

[0033] This invention provides a method for classifying the impact of relay protection services on production scheduling. Based on the status of protection devices at both ends of the relay protection service, the status of the lines to which the relay protection service belongs, and the number of protection device lines, a protection service guarantee classification strategy is formulated. This invention achieves service guarantee classification, guarantee level judgment, and intelligent classification presentation of the service network. Production tasks are scheduled according to the status of protection devices and lines, thereby reducing the risk of power system stability and safe operation affected by protection device failures or protection line failures.
