Due to the characteristics of randomness, volatility and low inertia, the large-scale integration of new energy units has changed the original power flow distribution and deteriorated the transient stability of the system, resulting in the migration of the system oscillation center, which can even affect the accurate action of the splitting control. Aiming at the problem that the integration of doubly-fed induction generator (DFIG) affects the migration law of the oscillation center, firstly the Thevenin equivalent model of DFIG is constructed and the operating characteristics are analyzed. And then the equivalent admittance model of DFIG is constructed. Finally, based on the equivalent admittance model, the migration law of the oscillation center in the DFIG-based wind power system is analyzed. The results show that the out-of-step center (OOSC) moves away from the DFIG-based wind farm integration point when DFIG generates reactive power and moves close to the integration point when DFIG absorbs reactive power. While the migration range of the oscillation center extends to the entire line.

There is a growing interest in small hydropower clean energy, and PMSM is the decisive service equipment in hydropower system, it is vital to ensure the stable and efficient operation of PMSM. However, there exist complex operating conditions make fault diagnosis difficult. Thus, in this paper, a diagnosis method for interturn short-circuit of PMSM for small hydropower is proposed. By analyzing the fault component, this method uses Extended State Observer (ESO) to estimate the fault signature of PMSM with interturn short-circuit. Then, the frequency tracking algorithm calculates the amplitude of faults signature and sets it as fault indicator. The method can be easily implemented in hydropower control system. Simulation results show the effectiveness of the proposed method.

In FRC experimental studies, it is found that the parameters of the plasma formed after the collision merging greatly depend on the plasma parameters of the formation zone. The design and optimization of the pulsed gas injection device will help the ionization of neutral gas and thereby improving the plasma parameters of the formation zone. In this paper, studies are focused mainly on the change process of gas distribution of pulse gas injection stage, and design of the pulse gas injection device. The research takes the control of gas distribution as the goal and ANSYS FLUENT as a simulation platform to carry out the study. First, in this paper, we introduce several gas injection schemes that can be used in the pulse gas injection device, and ANSYS Fluent is used for simulation comparison. Through the analysis of simulation results, we have determined the most suitable scheme for gas injection. Then, we analyze in detail the axial and radial distribution of neutral gas at different time under the optimal scheme. And the results show the advantages of multi-valve gas injection. Finally, we predict the appropriate time duration of gas injection and ionization time when the pressure source is 2 × 10^5 Pa.

The on-line monitoring of arrester resistive leakage current can effectively judge the operation of arresters. The fundamental current and the third harmonic current are the key indicators to judge the aging and damp of arrester, which are particularly important for the on-line monitoring of Metal oxide surge arrester (MOA). However, due to the influence of interphase interference and harmonic voltage of power grid, the accuracy of on-line monitoring results is not high and there are large errors. In this paper, the self capacitance and stray capacitance of three-phase arrester are calculated to separate the capacitive current from the total leakage current, so as to effectively reduce the influence of interphase interference. At the same time, the influence of grid harmonics on resistive third harmonic current is compensated to improve the accuracy of resistive leakage current. The algorithm builds a simulation model on the MATLAB / Simulink platform, obtains the capacitance values by using the algorithm, and verifies the correctness of the algorithm by evaluating the error between the extracted resistive current value and the ideal resistive current value. In addition, by analyzing the influence of interphase interference under different voltage fluctuations and different total harmonic distortion rate of power grid, it is proved that the algorithm can effectively reduce the influence of interphase interference.

With the rapid development of distributed power and new energy vehicles, the traditional distribution network is facing enormous challenges. The development of multi-station integration technology is an effective way to solve the above problems. In this paper, a new multi-station integration topology is proposed. The new multi-station integration topology uses soft open point (SOP) as the key equipment of the system, and adopts the hierarchical power supply mode for data center, electric vehicle charging pile and other function stations. Then, based on the new topology of multi-station integration and smooth switching of converter control mode, a coordinated control strategy is proposed. Through the coordinated control strategy to control the working mode of each function station, and then further optimize the system operation conditions. Based on Matlab/Simulink, the simulation model of multi-station integration is established, and two different application scenarios are analyzed. The simulation results verify that the new topology of multi-station integration and its coordinated control strategy effectively improve the voltage level of the distribution network, improves the reliability of sensitive load power supply, and ensure the safe and reliable operation of multi-station integration system.

The ambient moisture would diffuse into the film capacitor under the humid environment. The corrosion of electrodes would occur under ac voltage stress with the participation of the moisture, which results in a decrease of the capacitance. Thus, the moisture ingress is harmful to long-term reliable operation of film capacitors. In this paper, the process of moisture ingress is analyzed based on the Fick’s second law. An accelerated aging is carried out for two types of film capacitors to obtain the capacitance change and the weight gain. A staged fitting analysis is used to describe the capacitance change curves of capacitor samples. The effect of the moisture ingress on the lifetime of film capacitors is studied. The results indicate that the encapsulating material which provides better moisture resistance can slow down the electrode corrosion and significantly improve the lifetime of the film capacitors.

It is a great challenge to locate the partial discharge in power cables induced by different types of insulation defects. To overcome the challenge, a new method based on the Granndo model is developed in this paper. The incident and reflected waveforms are obtained through the cable partial discharge calibration experiment, and then the attenuation constant and dispersion constant of Granndo model are determined. The frequency spectrum of reflected wave and the wave velocity under corresponding frequency are determined through the simulation of cable propagation characteristics. Finally, the frequency band of frequency component concentration is selected for positioning calculation, which reduces the positioning error caused by waveform distortion and velocity uncertainty. Meanwhile, the calculation speed is faster than others.

The fluctuation of voltage stability is considered in the distributed generation (DG) planning of this paper. Taking the mean value and standard deviation of the voltage stability index and the comprehensive investment cost of the distribution network as the goal, a model for optimal siting and sizing of DG is established. An improved multi-objective particle swarm algorithm is proposed to obtain optimal Parato solution set, in which adaptive inertia weight is used to improve convergence, cross mutation is used to avoid falling into local optima, and particle density is used to filter non-inferior solution sets. Taking the IEEE33 node system as an example, the location and capacity of wind turbines and photovoltaics are selected and the results prove the effectiveness of this method.
