Description

Technical Field

[0001] The present invention relates to the technical field of power system fault analysis, and particularly to an acceptance detection system, method, device and medium for substation UAV deception equipment. Background Art

[0002] The time synchronization system is of great significance for the fault analysis, monitoring and control, and operation management of the power system. The operating state of the power system is changing at any time. After the state changes, especially after an accident, it is necessary to timely obtain real-time information in order to promptly handle the fault point, control its impact within a certain range, and ensure the safe and stable operation of the power system. And timely obtaining real-time information is also convenient for post-event analysis, analyzing the occurrence and development processes of various events, especially power system faults, and providing a basis for optimizing protection control and preventing catastrophic accidents. According to research, it is found that a UAV deception device SCG-200 has been installed in an existing pumped storage power station. This deception device belongs to a generative deception signal. Through on-site measurement, it is found that the UAV deception device reaches -60 dBm at both 5 mW and 10 mW of power, which is much greater than the signal strength of the GPS satellite signal reaching the ground, and will have a greater impact on the GPS time synchronization received by the substation time synchronization system. When the substation time synchronization system is out of sync, it will lead to the inability to find the real cause of the accident. For example, the fault point of the transmission line cannot be calculated through traveling wave ranging and cannot be processed in time, resulting in the expansion of the fault impact. More seriously, it will paralyze the power system and cause great losses to the local society.

[0003] The currently proposed time synchronization method and device between the local clock and the GPS clock in network measurement focus on correcting the time synchronization system to achieve high-precision time synchronization, and do not propose a standard for judging the time synchronization system, making it difficult to help solve the problems faced by the current substation.

[0031] To better understand the technical solutions provided by the embodiments of the present invention, some basic knowledge required to understand the technical solutions provided by the embodiments of the present invention will be briefly introduced below:

[0038] Currently, substations are gradually enabling drone deception devices to deal with the increasing incidents of drones straying into substations in the country. However, there is currently no detection method and acceptance standard for determining whether the drone deception device affects the substation time synchronization system. In addition, compared with the acceptance detection system and method for substation drone deception devices proposed in this patent, the focus of "Time Synchronization Method and Device for Local Clock and GPS Clock in Network Measurement" is to achieve high-precision time synchronization, and no standard for judging the time synchronization system is proposed. In response to this, this patent proposes an acceptance detection system and method for substation drone deception devices, enabling the drone deception device to operate in the substation, which is an urgent need for the prevention work of drones in substations.

[0039] See Figure 1 , an acceptance detection system for substation drone deception devices, which includes: a time synchronization module, a standard clock source module, and a time and frequency test module. Specifically, the time synchronization module is used to generate first time data, which is time information-containing data generated by the substation time synchronization system after being interfered by the drone deception device; the standard clock source module is used to generate second time data, which is time information-containing data generated according to the Global Positioning System or / and the Beidou Satellite Navigation System; the time and frequency test module is used to receive the first time data and the second time data, and compare and analyze the error between the first time data and the second time data, so as to evaluate whether the time output data of the substation time synchronization system under the interference signal of the drone deception device is qualified, and then judge whether the drone deception device can operate in the substation.

[0040] It should be noted that the power system time synchronization system mentioned in this embodiment provides time synchronization signals for all the time-synchronized devices in the dispatching master station system, substations, and power plants, and provides different time synchronization methods according to the requirements of different devices for time accuracy. For systems such as fault recorders, event recorders, microcomputer relay protection and security automation devices, telecontrol and microcomputer monitoring, the protocol soft time synchronization method can be adopted, and in necessary cases, the protocol soft time synchronization + pulse time synchronization method can be adopted. The pulse can be configured as PPS (pulse per second), PPM (pulse per minute), or PPH (pulse per hour) according to requirements, or the IRIG-B time synchronization method with higher time synchronization accuracy can be adopted; for systems with higher requirements for time accuracy such as PMU, traveling wave ranging system, and lightning location system, the soft time synchronization + PPS pulse per second or IRIG-B time synchronization method must be adopted to ensure the time synchronization accuracy; for devices with lower requirements for time such as information sub-stations and network servers, the NTP network time synchronization can be adopted.

[0041] See Figure 2 As an optional implementation manner, the time synchronization module includes: a time input unit, a time input unit, and a clock output unit. Specifically, the time input unit is used to receive data containing time information in multiple formats; an internal clock unit, which is used to convert the received data containing time information in multiple formats into data containing time information in a set format; a clock output unit, which is used to output the data containing time information in the set format.

[0042] It should be noted that the time input unit can obtain the pulse per second signal and serial communication to provide time information through the Beidou antenna and the receiving module. Specifically, there can be Beidou time information signals and information, GPS time information signals and information, IRIC-B (DC), and PTP. Exemplarily, the time information of Beidou mainly includes: year, month, day, hour, minute, second, leap second, quality, ephemeris, etc. Similarly, the pulse per second and time information provided by GPS can also be obtained. Exemplarily, IRIC-B (DC) is decoded and the pulse per second is extracted through a programmable logic circuit to obtain time information. Exemplarily, the time information is obtained by parsing, assembling, and extracting the pulse per second through a PTP network chip and a logic circuit. And corresponding calibration compensation is performed during the hardware transmission process to make each pulse per second accurate and consistent.

[0043] It should be noted that the internal clock unit can be composed of second edge difference measurement, rubidium atomic clock frequency standard source, pulse per second generator, and time counter, so as to generate time information such as seconds, minutes, hours, days, months, and years.

[0044] It should be noted that for power time synchronization requirements at different levels, the time output part of the time synchronization module can flexibly provide various time information output interfaces. Exemplarily, according to the common time synchronization signals in the power system, the output signals of the time synchronization module can be divided into pulse signals, serial port time message signals, IRIG-B code signals, and network time message signals. Among them, the pulse signals include PPS (pulse per second), PPM (pulse per minute), PPH (pulse per hour), and PPD (programmable pulse); the IRIG-B code follows the IEEE C37.118-2005 standard and is divided into two types: DC (direct current) and AC (alternating current) according to the coding form; the network time message signals are divided into NTP / SNTP and PTP (IEEE 1588) time synchronization messages.

[0045] See Figure 3 , as an optional implementation manner, the time and frequency test module includes a standard time unit, a time synchronization signal measurement unit, and a recording and analysis configuration unit. In some embodiments, it may also include a human-computer interaction interface. Specifically, the standard time unit is used to receive the second time data from the standard clock source module; the time synchronization signal measurement unit is used to receive the first time data from the time synchronization module; the recording and analysis configuration unit is used to compare and analyze the error between the first time data and the second time data, and evaluate whether the time output data of the substation time synchronization system under the interference signal of the UAV deception device is qualified based on the comparison result.

[0046] It should be noted that the time and frequency test module supports an internal high-precision standard time, and is built-in with a high-precision and high-stability rubidium atomic clock or a high-precision temperature-controlled crystal oscillator, which is tamed by external clock systems such as GPS and Beidou to generate a local standard time synchronized with UTC. Due to the influence of the high-temperature oscillator by the external environment, the second time generated after frequency division is inaccurate and unstable, resulting in a synchronization error between the local and external clock sources in the holdover state. The mathematical model of the influence of frequency on the holdover synchronization error is:

[0047]

[0048] A = A0 + Dt + A1(t) + A2(t) (2)

[0049] In the formula, δ t , t0, A, D, f1(t), f2(t), A1(t), A2(t), A0 respectively represent the influence of frequency on the holdover synchronization error, the time difference at t = 0, the frequency accuracy, the frequency aging rate, the influence of frequency stability on δ t the influence of the external characteristics of frequency on δ t the influence of frequency stability on A, the influence of the external characteristics of frequency on A, and the frequency calibration accuracy at t = 0.

[0050] According to the above principle, a rubidium atomic clock or a high-precision temperature-controlled crystal oscillator can be used to provide the working clock. The short-term stability of a rubidium atomic clock can reach up to 10 -12 orders of magnitude, and the accuracy is ±5×10 -11 orders of magnitude. In the satellite locking mode, the output accuracy of the rubidium atomic clock can reach 2×10 -12 .

[0051] During the phase discrimination process, in order to obtain the phase difference, the tester uses the Kalman filtering algorithm for control. During the process of restoring the phase discrimination value, a curve fitting algorithm is also used to voltage-control the internal oscillator. Thus, the taming and adjustment of the internal oscillator are realized, and the accuracy and long-term stability of the internal oscillator are improved.

[0052] In addition, the time synchronization signal measurement unit can realize the input and measurement of time signals for 8 channels simultaneously. The supported interface channels include TTL channels, RS-232 channels, RS-485 channels, optical port channels, dry contact channels, IRIG-B(AC) channels, network interface channels, etc. The hardware of all network interfaces supports the hardware timestamp marking function, providing high-precision time error measurement.

[0053] In addition, the recording, analysis, and configuration unit can display, continuously record, and store measurement data in real time, and perform graphical comprehensive analysis on various test data to automatically generate test reports.

[0054] In this way, this acceptance detection system can perform multi-channel simultaneous measurement and comparative analysis. The analysis results can be displayed in real time through the human-computer interaction interface. The real-time display content includes: measurement signal type, parsing the specific content carried by the current second's message, current deviation measurement value of the signal arrival time, average deviation measurement value, standard variance of the measurement value, number of samples, etc. Further, it has a network delay analysis function. It can capture PTP (IEEE 1588), NTP messages to assist in analyzing network delay. It has various forms of recording measurement data. Further, it can continuously record measurement data for more than 1 month, and the recording time length can be freely set. It can perform graphical comprehensive analysis on various measurement data and automatically generate test reports. Further, it has a data file analysis and processing function. Further, it can analyze, export, and delete the test data saved on the test hard disk. Further, it is equipped with a built-in battery and an uninterruptible power supply module to achieve high portability of the device.

[0055] As an alternative implementation, the standard clock source module uses a time source that transfers and calibrates the magnitude to carry out the test work as the local UTC time source. The time accuracy of the standard time source relative to UTC time is better than 1 / 4 of the nominal time accuracy of the device under test and has a second pulse output function.

[0056] See Figure 4 , the following will introduce the specific steps of using this system to test the accuracy of the substation time synchronization system by the UAV spoofing device. The following is the impact of the interference signal when the UAV spoofing device uses different signal generation powers at a certain preset distance on the time synchronization accuracy of the power system. The test site layout diagram is as Figure 4 shown.

[0057] Enable the UAV spoofing device and set its transmission power and operating frequency band to generate a continuous interference signal, and release the spoofing interference for 2 hours.
