Experimental investigation of irradiation effect of low-frequency wide-pulse electric field on typical intelligent control equipment

Jiuliang Xiong Liuhong Huang Yaohui Zhang Jie Yang Yuebo Li

To analyze the interference effects on intelligent control equipment of low-frequency wide-pulse electric field, irradiation experiment system is established, and experiments are carried out. The effect rules and interference mechanism are confirmed. The results show that low-frequency wide-pulse electric field, which rise time is not less than 10ns and the pulse width is more than 1ms, can affects the normal working performance of the test equipment. But it cannot damage the test equipment even the field intensity reaches 100kV/m. To the intelligent control equipment, the direct effect and cable coupling of the irradiation field lead to the interference phenomenon. The interference is more serious when the orientation of connection line is in accordance with the polarization direction of the irradiation field. The rise time and electric field intensity are two main factors that affect the interference degree.

Method of Dual Threshold Intermittent Target Tracking Based on Infrared/Radar Cross Location

Modern Radar (2012)

Jiuliang Xiong

In order to solve the target-losing period problem in netted fire-control radars' intermittent tracking,dual threshold infrared /radar intermittent target tracking method is proposed.Firsdy,improved algorithm of antenna beam control is used to eliminate the effect of correlative errors.Then,the method uses dual threshold to control sensor's working time,and increases silent radar' s response time by cross location of infrared sensors.At last,sequential filtering fusion algorithm based on data compression is used for dissimilar data fusion,and continuous target track is formed.Simulation results showed that this method could weaken the effect of target-losing period problem and improve system performance.

Development and Performance Test of SREMP Measurement System

Jiuliang Xiong Feng Liu Yuebo Li

To the characteristics of the undertest SREMP electric field (rise time is shorter than 10ns, pulse width is wider than 1ms, field strength is higher than 100kV/m), a series of wide pulse and high field strength measurement systems were developed in the paper by theoretical analysis, simulation and circuit design. Performance test results show that the measurement system's rise time response is shorter than 5ns, and pulse width response is wider than 1ms. The dynamic range of measurement system is wider than 50dB, and the field strength measurement capability can be extended from 30V/m to1000kV/m. Using the developed series measurement systems interdependently, the pulsed electric field can be tested reliably.

Interference effects research on a certain shortwave radio of low frequency wide pulse electric field

AOPC 2020: Optical Sensing and Imaging Technology (2021)

Jiuliang Xiong Jie Yang Yaohui Zhang Yuebo Li Zheng Pan

To analyze the interference effects on a certain shortwave radio of low frequency wide pulse electric field, irradiation experiments are carried out. Through theoretical analysis, simulation and experiment, the effect rules and interference mechanism are confirmed. The results show that low frequency wide pulse electric field, which rise time is not less than 10ns and the pulse width is more than 1ms, can interferes the normal working performance of shortwave radio. But it cannot damage the shortwave radio even the field intensity reaches 100kV/m. The main interference phenomenon is communication interruption, while it can comeback in a few seconds, usually about three or five seconds. It should be noted that the interference phenomenon happens in a certain frequency range. And in the range, the threshold interference field intensity rising with the increase of the frequency.

Simulation Analysis of a Composite Simulator for the Source-region Electromagnetic Pulse Environment

Liuhong Huang Jiuliang Xiong Cui Meng Pan Zheng Jie Yang

To simulate the source-region electromagnetic pulse generated by ground nuclear explosions, a composite simulator is constructed by spatially combining a magnetic field coil with a guided-wave simulator. The CST software is used to analyze influences of the guided-wave simulator, the coil and shielding chamber on the electromagnetic fields in space. Simulation results show that the coil can limit the spatial electric field distribution and may cause waveform distortions. To avoid this distortions, rising time of the guided-wave simulator's excitation should be greater than 30ns. The guided-wave simulator has little effect on the composite simulator's magnetic fields. The shielding chamber can reduce peak value of magnetic flux density in the working area, but don't cause waveform distortions. These results verify that this composite simulator can provide pulsed electric and magnetic fields, and it can support research on the damage effects of the source-region electromagnetic pulse.

Influence analysis of magnetic field coil on interior electric field of bounded-wave simulator based on circuit model

Liuhong Huang Cui Meng Jiuliang Xiong Yuebo Li Jie Yang

To simulate the source region electromagnetic pulse, a composite system was constructed by spatially combining a magnetic field coil with a bounded-wave simulator. This system can support the electromagnetic environmental effect tests that have both a pulsed magnetic field and pulsed electric field. However, the simulation results show that the magnetic field coil may cause electric field waveform distortion in the parallel section of the bounded-wave simulator. To explain the mechanism of electric field waveform distortion, a viewpoint was put forward that the spatial interaction relationships between the external magnetic field coil and the upper and lower plates of the bounded-wave simulator can be represented by three equivalent capacitors. In addition, the asynchronism of electric field changes was due to the charge-discharge property of the upper and lower capacitor on the intermediate capacitor. Furthermore, a circuit model based on these equivalent capacitors and inductor was established. The calculation results based on the circuit simulation software LTspice showed that, the voltage waveforms of the equivalent capacitors can be consistent with the electric field waveforms in the corresponding spatial region. These results verify the correctness of the equivalent capacitors and the circuit model proposed in this paper.

Measurement and Analysis of the Transient Electric Field Generated by the Operation of the Disconnector in a 330 kV Substation

Xu Kong Kai Liu Yuebo Li Yaohui Zhang Jiuliang Xiong

The making and breaking operation of the high voltage switch can generate transient electromagnetic field around the switch. This kind of switching transient EM field is a kind of radiated electromagnetic interference to the electronic equipment in the substation. On the other hand, it also contains the operation state information of the switch itself. So, this paper briefly reviews the research status on the switching transient electromagnetic environment in the substation. In addition, this paper measures the switching transient E-field pulses caused of the disconnector in a 330 kV substation. The measurement results can reflect the basic waveform characteristics of the switching transient E-pulse in both time and frequency domain. More importantly, the spectral differences between the three phases of the disconnector are also found. This is useful for locating pulses sources in the substation.
