[0002] The relay protection system is a key device to ensure the safe and stable operation of the power grid. The relay protection system identifies and isolates faults by real-time monitoring of a series of electrical parameters, which can not only effectively prevent the fault from further expanding, but also ensure the continuous power supply of the power system.

[0003] The operating parameters of relay protection equipment will change with the changes in the monitoring environment. The existing real-time status monitoring and early warning methods for relay protection equipment are unable to monitor the relay protection equipment in real time according to the changing operating parameters of the relay protection equipment, resulting in low accuracy of real-time status monitoring and early warning for relay protection equipment.

[0005] In order to achieve the above object, the present invention adopts the following technical solution: In a first aspect, the present invention provides a method for real-time status monitoring and early warning of a relay protection device, comprising the following steps: Acquire health parameters and environmental parameters of the relay protection device in real time, arrange the obtained health parameters and environmental parameters of the relay protection device according to the sequence number, and obtain the health parameters and environmental parameters of the relay protection device after the sequence arrangement; Compare the health parameters and environmental parameters of the relay protection equipment after sequence arrangement with the preset health standard parameters and environmental standard parameters to obtain the comparison results, and preliminarily determine the corresponding early warning strategy based on the obtained comparison results; The average values ​​of the health parameters and environmental parameters after sequence arrangement within a set period are selected and compared with the preset safety values ​​to obtain a comparison result, and based on the comparison result, it is judged whether the overall health status and overall environmental status of the relay protection equipment are normal.

[0006] A further improvement of the present invention is that when the difference between the health parameters of the relay protection device after sequence arrangement and the preset health standard parameters is greater than or equal to the first set threshold and less than the second set threshold, it indicates that the health parameters of the relay protection device are within the safe value range and no health condition risk warning is issued; when the difference between the health parameters of the relay protection device after sequence arrangement and the preset health standard parameters is greater than or equal to the second set threshold, it indicates that the health parameters of the relay protection device exceed the safe value range and a health condition risk warning is issued.

[0008] A further improvement of the present invention is that if the average values ​​of the health parameters after sequence arrangement within a set period are all within the preset safety value range, it indicates that the overall health status of the relay protection equipment is normal; if the average values ​​of the health parameters after sequence arrangement within the set period are all beyond the preset safety value range, it indicates that the overall health status of the relay protection equipment is abnormal.

[0009] A further improvement of the present invention is that an average value is calculated by calculating the difference between the environmental parameters after sequence arrangement in the current cycle and the environmental standard parameters and the difference between the environmental parameters after sequence arrangement in the previous two cycles and the environmental standard parameters; if the average values ​​of the environmental parameters after sequence arrangement in the set cycle are all within the preset safety value range, it indicates that the overall environmental condition of the relay protection device is normal; if the average values ​​of the environmental parameters after sequence arrangement in the set cycle are all beyond the preset safety value range, it indicates that the overall environmental condition of the relay protection device is abnormal.

[0010] A further improvement of the present invention is that after determining whether the health status and environmental status of the relay protection device are normal, if the overall health status and overall environmental status of the relay protection device are abnormal, the abnormal health parameters and environmental parameters can be corrected.

Compared with the existing real-time status monitoring and early warning method for relay protection equipment, the real-time status monitoring and early warning method for relay protection equipment proposed by the present invention compares the health parameters and environmental parameters of the relay protection equipment after sequence arrangement with the preset health standard parameters and environmental standard parameters to obtain a comparison result, and preliminarily determines the corresponding early warning strategy based on the obtained comparison result. The average value of the health parameters and environmental parameters after sequence arrangement within a set period is selected and compared with the preset safety value to obtain a comparison result, and based on the obtained comparison result, it is judged whether the overall health status and overall environmental status of the relay protection equipment are normal. It can be seen that the present invention not only preliminarily determines the corresponding early warning strategy based on the comparison result obtained between the health parameters and environmental parameters of the relay protection equipment after sequence arrangement and the preset health standard parameters and environmental standard parameters, but also evaluates the overall health status and overall environmental status of the relay equipment by calculating the average value within the set period.

[0016] In order to further understand the content of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0017] The real-time status monitoring and early warning method for relay protection equipment proposed in the present invention selects the average values ​​of health parameters and environmental parameters after sequence arrangement within a set period and compares them with preset safety values ​​to obtain comparison results, and judges whether the overall health status and overall environmental status of the relay protection equipment are normal based on the obtained comparison results. Compared with the prior art, the present invention effectively solves the problem in the prior art that the relay protection equipment cannot be monitored in real time according to the changing operating parameters of the relay equipment, resulting in low accuracy of real-time status monitoring and early warning of the relay protection equipment.

[0018] Embodiment 1: The flowchart of the real-time status monitoring and early warning method of the relay protection equipment of the present invention is as follows: Figure 1 As shown, the real-time status monitoring and early warning method of relay protection equipment of the present invention comprises the following steps: S1.

Select the average values ​​of the health parameters and environmental parameters after sequence arrangement within the set period and compare them with the preset safety values ​​to obtain the comparison results, and judge whether the overall health status and overall environmental status of the relay protection equipment are normal based on the obtained comparison results.

[0021] Embodiment 2: The schematic diagram of the real-time status monitoring and early warning system for relay protection equipment of the present invention is as follows: Figure 2 As shown, the real-time status monitoring and early warning system for relay protection equipment of the present invention includes a data acquisition module, a sequence number arrangement module, an early warning strategy preliminary determination module and a relay protection equipment status judgment module.

[0022] The data acquisition module is used to obtain the health parameters and environmental parameters of the relay protection equipment in real time.

[0023] The serial number arrangement module is used to arrange the obtained health parameters and environmental parameters of the relay protection equipment according to the serial numbers to obtain the health parameters and environmental parameters of the relay protection equipment after the sequence arrangement.

[0024] The early warning strategy preliminary determination module is used to compare the health parameters and environmental parameters of the relay protection equipment after sequence arrangement with the preset health standard parameters and environmental standard parameters to obtain the comparison results, and preliminarily determine the corresponding early warning strategy based on the comparison results.

[0025] The relay protection equipment status judgment module is used to select the average values ​​of the health parameters and environmental parameters after sequence arrangement within a set period and compare them with the preset safety values ​​to obtain the comparison results, and judge whether the overall health status and overall environmental status of the relay protection equipment are normal based on the comparison results.

[0026] Embodiment 3: S1. Acquire the health parameters and environmental parameters of the relay protection device in real time, arrange the obtained health parameters and environmental parameters of the relay protection device according to the sequence number, and obtain the health parameters and environmental parameters of the relay protection device after the sequence arrangement.

[0027] First, the health parameters and environmental parameters of the relay protection equipment are obtained in real time through the data collector. The health parameters include current, voltage, frequency and phase sequence. The environmental parameters include temperature, humidity, atmospheric pressure and ground resistance.

[0028] Then, the obtained health parameters and environmental parameters of the relay protection device are arranged according to the sequence numbers to obtain the health parameters and environmental parameters of the relay protection device after sequence arrangement.

[0029] S2. Compare the health parameters and environmental parameters of the relay protection equipment after sequence arrangement with the preset health standard parameters and environmental standard parameters to obtain comparison results, and preliminarily determine the corresponding early warning strategy based on the comparison results.

[0030] When the difference between the health parameters of the relay protection device after sequence arrangement and the preset health standard parameters is greater than or equal to the first set threshold (the first set threshold in this embodiment is 0) and less than the second set threshold (the second set threshold in this embodiment is 0.02), it means that the health parameters of the relay protection device are within the safe value range and no health status risk warning is issued.

[0031] When the difference between the health parameters of the relay protection device after sequence arrangement and the preset health standard parameters is greater than or equal to the second set threshold (the second set threshold in this embodiment is 0.02), it means that the health parameters of the relay protection device exceed the safety value range, and a health status risk warning is issued.

[0032] When the difference between the environmental parameters of the relay protection device after sequence arrangement and the preset environmental standard parameters is greater than or equal to the third set threshold (the third set threshold in this embodiment is 0) and less than the fourth set threshold (the fourth set threshold in this embodiment is 0.01), it means that the environmental parameters of the relay protection device are within the safe value range and no environmental condition risk warning is issued.

[0033] When the difference between the environmental parameters of the relay protection device after sequence arrangement and the preset environmental standard parameters is greater than or equal to the fourth set threshold (the fourth set threshold in this embodiment is 0.01), it means that the environmental parameters of the relay protection device exceed the safety value range, and an environmental risk warning is issued.

[0034] The health standard parameters preset in this embodiment are specifically as follows: the rated current should be set to 1.2 to 1.5 times the fault current; the rated voltage should be selected based on the rated voltage of the power system and the allowable overvoltage level; the rated frequency should be selected based on the nominal frequency of the power system (for example, 50Hz or 60Hz); the phase sequence should be determined based on the action time and recovery time.

[0035] The preset environmental standard parameters of this embodiment are specifically as follows: the indoor temperature should be controlled between -5°C and +40°C or -10°C and +55°C; the outdoor temperature should be controlled between -25°C and +55°C; the relative humidity should be set between 5°C and 95°C; the atmospheric pressure should be set between 70kPa and 110kPa; and the grounding resistance should comply with the relevant provisions of the current national standard "General Specifications for Electronic Computer Sites" GB / T 2887.

[0036] S3. Select the average values ​​of the health parameters and environmental parameters after sequence arrangement within the set period and compare them with the preset safety values ​​to obtain the comparison results, and judge whether the overall health status and overall environmental status of the relay protection equipment are normal based on the obtained comparison results.

[0037] If the average values ​​of the health parameters after sequence arrangement within the set period (three periods are selected in this embodiment, each period is 15 minutes) are all within the preset safety value range (the preset safety value range is the middle value of each health parameter. If the health parameter range is an even number, the average value between two even numbers is taken), it indicates that the overall health status of the relay protection device is normal. If the average values ​​of the health parameters after sequence arrangement within the set period (three periods are selected in this embodiment, each period is 15 minutes) are all beyond the preset safety value range, it indicates that the overall health status of the relay protection device is abnormal.

[0038] The difference between the environmental parameters after sequence arrangement in the current cycle and the environmental standard parameters and the difference between the environmental parameters after sequence arrangement in the previous two cycles and the environmental standard parameters are averaged. If the average values ​​of the environmental parameters after sequence arrangement in the set cycle (three cycles are selected in this embodiment, and each cycle is 6 hours) are all within the preset safety value range (the preset safety value range is the middle value of each environmental parameter. If the environmental parameter range is an even number, the average value between two even numbers is taken), it indicates that the overall environmental condition of the relay protection device is normal. If the average values ​​of the environmental parameters after sequence arrangement in the set cycle (three cycles are selected in this embodiment, and each cycle is 6 hours) exceed the preset safety value range, it indicates that the overall environmental condition of the relay protection device is abnormal.

[0039] After determining whether the health status and environmental conditions of the relay protection equipment are normal, if the overall health status and overall environmental conditions of the relay protection equipment are abnormal, the abnormal health parameters and environmental parameters can be corrected. The calculation formula for correcting abnormal health parameters and environmental parameters is:

[0040] in, is the corrected value of the first abnormal health parameter and environmental parameter, is the corrected value of the Nth abnormal health parameter and environmental parameter, are the standard values ​​corresponding to multiple abnormal health parameters and environmental parameters, is the value of the first abnormal health parameter and environmental parameter before correction, It is the value of the Nth abnormal health parameter and environmental parameter before correction.

[0041] If the corrected value of the abnormal health parameter and environmental parameter is 0, it means that the correction of the abnormal health parameter and environmental parameter is effective. If the corrected value of the abnormal health parameter and environmental parameter is not equal to 0, it means that the correction of the abnormal health parameter and environmental parameter is invalid and the correction value needs to be calculated again.
