In the realm of electromagnetic radiation (EMR) data collection and simulation, where noise is an ever-present challenge, this study introduces a novel approach for noise reduction employing an enhanced WaveNet model. EMR is deeply intertwined with modern life, finding applications in everything from household Wi-Fi networks to advanced mobile communications and industrial instrumentation. Nevertheless, the potential health and environmental ramifications of EMR necessitate the precise monitoring and assessment of its impact. The central issue in EMR monitoring lies in effectively distinguishing the valuable signal from intrusive background noise. Our method combines the capabilities of WaveNet, a potent deep learning architecture, with a Fast Fourier Transform (FFT) module and an atention mechanism. This enhancement aims to harness WaveNet's prowess in extracting meaningful features and its innate self-atention mechanisms to elevate the quality of EMR data by reducing noise. In our comprehensive experimental investigations, we conducted a comparative analysis, piting classical filtering techniques, including median and Gaussian filters, against neural network algorithms such as LSTM, GRU, and TCN. The outcomes undeniably underscore the superior performance of our proposed method in denoising electromagnetic radiation data. This advancement not only bolsters the quality of the data but also provides substantial support for the broader endeavor of EMR monitoring and assessment. It is noteworthy that both traditional methods and advanced neural network techniques have demonstrated their effectiveness in handling EMR data denoising. However, our proposed approach, while building upon these foundations, modestly presents itself as a notable enhancement. It is this humble enhancement that we believe contributes to the ongoing pursuit of refining EMR monitoring and assessment. In summation, our research humbly advances the field of noise reduction in EMR data through a no

For analyzing the power system with high penetration of wind power, it is important to establish accurate models of wind turbines and wind farms, which is a basic and important work. In the analysis of wind power grid integration, it is necessary to aggregate the equivalent value of the wind farm into one or a few wind turbines. At present, there are two commonly used equivalence methods: current source multiplication (commonly used in commercial software) and full dynamic aggregation method. The former achieves wind farm equivalence by multiplying the output current of a single wind turbine generator, while the latter dynamically aggregates the wind farm into one or several large wind turbine generators. There is still a lack of research on the differences between the two. Based on the actual wind farm structure, this paper studies the electrical characteristics of steady-state operation and transient fault ride through operation using single machine dynamic aggregation method and current source multiplication method separately, and compares the equivalent simulation results with the detailed wind farm simulation results. The equivalent accuracy of the single machine aggregation method and the current source multiplication method is calculated to provide a reference for method selection in wind farm equivalent modeling.

With the increase of DC feed power and the decrease of the number of synchronous machines, receiving-end power system takes a serious threat to the transient voltage stability. Therefore, a transient voltage stability preventive control strategy for DC receiving-end power system is proposed in this paper. The whole method is decomposed into three sub-problems: transient voltage stability assessment, sensitivity computation and optimal control. A transient voltage stability index suitable for the sensitivity method is used to construct the transient voltage stability constraints. The accuracy and efficiency of the solution algorithm are improved by limiting the effective control interval of sensitivity and selection of the initial control set. The method has been applied in a provincial power grid in southern China. The results verifies the effectiveness of the proposed method.

The synchronization instability is one of the main issues for the operation of grid-following converter (GFL). Analogizing to the synchronous generator mechanism, GFL synchronism can be modelled in the form of swing equation. Thus, under the assumption that the damping is negligible, the equal area criterion (EAC) method is used to determine the GFL synchronization stability. However, in practice the damping is significant and inconstant during the transients. Sometimes, the damping becomes negative during the transients even is positive in the pre-fault, and resulting in the instability. The effect of the damping on the synchronization stability has not been thoroughly investigated. This paper visually reveals this effect. The simulation results show that the negative damping of GFL may lead to an optimistic prediction of synchronization stability by EAC method. © 2022 IEEE.

As new energy sources are increasingly integrated into the power grid on a large scale, the proportion of gridconfigured offshore wind power DC delivery systems in the power system is increasing yearly. However, there is a lack of dynamic characteristics during its transient process. Therefore, this paper investigates the transient synchronous stability mechanism of grid-connected converters with virtual synchronous generator (VSG) control and proposes measures to enhance their transient stability. Firstly, the transient stability model of the offshore wind power DC sending system with VSG during grid fault is established to obtain the factors influencing the converter's transient stability under different faults. The control method of VSG is improved according to the system's voltage coupling effect. Finally, Matlab/Simulink is used to build a simulation model of the offshore wind power grid-connected model under the inaccessible fault, which demonstrates the effectiveness of the improved control method of the VSG and the active control strategy of the grid-side three-phase short-circuit fault.

By collecting the traveling wave, power frequency component, and waveform characteristic information generated when the short circuit fault occurs on the transmission line, this paper calculates and analyzes the fault location and fault cause identification, monitoring the transmission line with frequent fault trips to obtain the fault detection characteristics of the transmission line. According to the different fault cause types, the impedance time-varying characteristics of the flash over the channel are reflected in the difference of fault transient traveling wave, and the influence of different channel characteristics on the power frequency and high-frequency signal before and after the fault flash over is studied to realize the accident sample. Open self-learning improves the identification ability of accidents such as bird damage, pollution flash, wind short circuit, etc., achieving fast and accurate judgment of the cause of transmission line failure and improving the efficiency of diagnosis of transmission line fault causes. The research results show that through the effective extraction of distributed traveling wave characteristics, the ability to diagnose the cause of faults in transmission lines is greatly improved.

Real-time electromagnetic transient simulation can quickly analyze and solve the problems in complex large-scale power systems, realize accurate prediction and diagnosis of faults, and is a necessary means to promote the implementation of new power systems. However, the real-time simulation of electromagnetic transient puts forward strict requirements for the real-time performance of the underlying operating system. In this paper, the test method of system runtime jitter on Linux platform is designed, and the causes of jitter are analyzed based on the test results, and the control method of runtime jitter is studied. The experimental results show that the jitter of the system can be controlled in nanosecond level after using the methods of interrupt shutdown, CPU core binding and configuration of NOHZ_FULL, which can meet the needs of real-time simulation of electromagnetic transient.

With the continuous expansion of the scale of offshore wind power, its grid-connected access puts forward higher requirements for the stability and reliability of the power grid. High voltage direct current (HVDC) systems, primarily modular multilevel converter (MMC) technology, are ideal for offshore wind power grid integration due to their high efficiency, reliability and flexibility. However, the inherent parasitic losses in long-distance DC transmission lines substantially degrade system operational efficiency. To address this challenge, this study develops a bipolar control architecture for offshore wind-integrated MMC-HVDC systems, explicitly incorporating line loss dynamics into the control loop design. This strategy significantly improves the power transmission efficiency by optimizing the power control at the wind farm end and the land access end, combined with the loss compensation mechanism of the DC line. The proposed control strategy can improve the power transmission efficiency of the system by 4 % to 6% compared to the legacy control strategy, with concurrent preservation of system dynamic stability and functional reliability.

Based on impedance analysis, this paper studies the stability of Offshore wind farm integration based on a permanent magnetic synchronous generator (PMSG) through the MMC-HVDC system and focuses on the control of MMC zero-sequence circulating current (ZSCC). Firstly, the impedance model of a permanent magnetic synchronous generator (PMSG) and sending-terminal MMC is built by multi-harmonic linearization, and then the influence of frequency coupling effect on the impedance model is analysed. Secondly, a zero-sequence circulation current impedance shaping control method is proposed to suppress the oscillation of MMC effectively. Finally, the stability analysis and the impedance modeling method are verified by RT-LAB hardware in the loop real-time simulation system.
