Characteristics of harmonic current generated by single-phase converter with L filter for distributed generator are studied. The variation of transient current in a carrier cycle is derived by the differential equation of the system in time domain. Then compared transient current and fundamental current generated by convertor with no grid, harmonic current under condition of different modulation ratio is analyzed. When and why harmonic current is the largest and smallest in a fundamental cycle is presented through the study of variation tracking capacity of transient current. The maximum and minimum TDD/ with a fixed carrier ratio is proposed. The current generated by the joint action of converter and grid voltage source is also analyzed to explain the relationship of variation tracking and harmonic currents. Simulation results in different operation mode verified the correctness of the proposed theoretical results.

10kV distribution network is always a neutral point ungrounded system. Single-phase line break and grounding fault frequently occurs in 10kV distribution networks, threats the safe and stable operation of power grid and damages people's lives and properties. A methodology to differentiate type of single-phase line break fault is proposed in this paper, which uses sequence network and symmetrical components method to analyze and summarize the voltage and current variation when various single-phase line break fault occurs, then draw the voltage phasor diagram and current phasor diagram. The voltage and current variation and phasor diagrams will provide criteria for the detection and identification of single-phase line break fault in ungrounded distribution networks. Simulation results show the accuracy of the theoretical analysis in this paper.

To lessen mutual-thermal-coupling effects, both n-p-n and p-n-p GaAs/InGaAs/InGaP collector-up heterojunction bipolar transistors (HBTs) with an efficient thermal-removal design (TRD), which can be used in power-amplifier circuits for the next-generation renewable-energy system, have been presented in this report. Notably, different from lately proposed thermal-properties-enhancing collector-up structures and thermal-via-hole configurations, the TRD-implemented multi-finger devices, with a graded InGaAs base but without the conventional collector conformation, are demonstrated to achieve compelling heat-removing thermal performance. Preliminary results show that the thermal coupling has been substantially decreased, and nearly 20% improvement, compared to previous work, in the surface temperature-rise ratio is obtained. Unprecedentedly, the TRD has a stronger influence on the p-n-p device than on the n-p-n device based on the pragmatic observations.

Due to the professionalism and particularity of the power equipment, a reasonable inventory equipment quota forecasting and purchasing plan can guarantee the electrical power construction and maintenance work smoothly. Furthermore, an accurate quota forecasting can also save a large volume of liquid funds for the power companies. This paper establishes a reasonable spare parts demand forecasting and inventory quota model based on SVM algorithm which takes material historical demand, repair schedule, the failure rate of the equipment and operating environment into full consideration. Moreover, the spare parts of electrical equipment in distribution network are divided into Class A, Class B1 and Class B2 through the activity based classification, through which the inventory quota method based on the different types of inventory management model is established. Finally, the calculation results of actual distribution power network show that the proposed SVM model is of high prediction accuracy, providing a simple and effective solution for inventory equipment management of electricity equipment.

In this paper, the bifurcation and chaos in the operation of H-bridge inverter modulated by bipolar SPWM is studied. The one-dimensional discrete iterated mapping model under proportional control is established. Effects of the input voltage E on the system performance are analyzed by using bifurcation diagram, folded diagram. The time-domain waveforms with different proportional coefficients are obtained by Mat-lab/Simulink, which verify the correctness of theoretical analysis. Finally, the nonlinear behavior in the inverter caused by the variation of other circuit parameters like proportional coefficient k, load resistance R, and inductance L is investigated through bifurcation diagrams. The results have important guiding significance and application value for designing and debugging the single-phase H-bridge inverter.

Xiluodu ±500 kV HVDC Double-circuit-on-the-same-tower Transmission Project is the first HVDC transmission project with two HVDC circuits sharing the same converter stations in the world. This project is different from others in that the double circuits may operate independently in single-circuit mode or coordinately in double-circuit mode. This paper analyzes the hierarchical structure of the control systems for this kind of HVDC transmission systems, and studies in depth the double-circuit power control functions according to the unique characteristics of the double-circuit control hierarchies. A simulation model is built in PSCAD / EMTDC for a simulative analysis of three typical operation control modes. The simulation results verify the feasibility of coordinated controls for double-circuit-on-the-same-tower HVDC transmission systems and have a certain guiding significance for actual project operation.

A ferroresonace circuit consists of a voltage source, a capacitor and a nonlinear inductor connected in series. The initial flux in transformer core plays an important role on the onset of different types of ferroresonance modes. In this paper, the likelihood of the onset of sustained fundamental mode ferroresonance under the influence of the initial flux is investigated. The flux linkage, the voltages across the transformer and the voltage across the series capacitor are investigated by using Matlab toolbox. The initial results are presented and then verified with the simulation results obtained from ATP software. The results between them are found in good agreement.

When rolling bearing has mechanical localized faults in its various components, pseudo-cyclostationary transient impact signal will be generated. But when in transient faults, this weak impact signal may submerge in strong background noise and gear vibration signal. In this paper, adaptive threshold wavelet de-noising method is used to reduce background noise, then Kurtosis of the noise-reduction signal is calculated in time domain. By comparing the calculation result with a given threshold, a conclusion can be made that whether the bearing is healthy or having mechanical localized faults. When the bearing is diagnosed as faulty in time domain, Kurtogram is used to find out a most suitable pass-band in frequency domain by maximizing the Kurtosis value. Band-pass filtering and do demodulation to this band-pass signal, the faulty component can be positioned precisely and reliably.

This paper proposes an optimal sizing and control strategy for islanded microgrid, consisting of renewable energy sources such as wind turbine generators (WT) and solar photovoltaic generators (PV), diesel generators (DE) and battery storage system (BS). The problem is formulated to minimize the annualized system cost (ASC) based on a control strategy with two modes. In mode 1, BS is the main power source and DE is backup power, but in mode 2, the master unit is DE and BS assists DE to improve reliability and economic operation benefit. Combination with the control strategy, particle swarm optimization (PSO) is used for a minimized optimization objective of the annualized system cost including initial cost, maintenance and operation (M&O) cost, replacement cost, fuel cost and pollutant emission cost. A case study of an islanded microgrid in Dong'ao Island is introduced to verify the proposed method.

A comparative analysis of neural networks and statistical time-series methods in the electricity price forecasting of the Iran power market is conducted. An error back propagation algorithm is applied to train neural networks. The time series methods discussed in previous research were considered as benchmarks in the comparison. Two case studies are investigated based on the proposed methods to examine the impact of load ramp in the electric energy price. Only the timeseries of energy price is considered as inputs in the first case and both of the price and load are considered as inputs in the second case. The computational results validate the capability of neural networks in energy price forecasting and indicate that the load ramp is one major factor for determining the energy price.
