This paper presents an approach to the detection of harmonics and reactive currents in single-phase circuit according to the orthogonal characteristic of sine function. The method is simple and practical, which cannot only detect the current component in the distorted current but can also obtain the sum of the active and reactive current. Meanwhile, the presented method possesses fine digital filtering characteristics, and has better qualities in real-time and dynamic response characteristics in comparison with the harmonics detection through the simulated low pass filter. The MATLAB simulation studies illustrate the effectiveness of the proposed method. © 2006 IEEE.

The relation between the voltage at the end of the opened phase conductor (VATEOTOPC) and the sum voltage of the two healthy phases (SVOTTHP) are analyzed. An integrated criterion based on the relation is proposed to determine the fault nature of single-phase faults. The integrated criterion is simple in scheme and can be realized easily. It can distinguish between temporary and permanent faults effectively and has good adaptability to load currents and fault distances. Simulation tests show that the conclusions in this paper are correct.

The power line tower lightning surge impedance is computed using an electromagnetic field approach. After comparing the results computed by our method and those tested with both a vertical conductor and reduced scale 4-poles model of tower, the method we used is proved to be right and more practical as the soil and the grounding system of the tower can be considered in the method. Using this method, the lightning surge impedance of the full scale UHV tower with grounding system is analyzed and the results show that the lightning surge impedance of a tower on the perfect ground has a little difference with those of an actual tower considering both its grounding system and soil resistivity, and when the soil resistivity is changed, the surge impedance changes slightly. Furthermore, a circuit model of the tower is obtained by Vector Fitting method based on the results we computed. Using the circuit model, the lightning surge performance of a power transmission line can be analyzed more accurately by EMTP or other methods.

An equivalent continuous-time state-space model for VSC-HVDC in the synchronous dq reference frame has been established in the paper. Based on the model, relevant control strategies have been developed for the cases of supplying active and passive systems. The Multi-Input Multi-Output (MIMO) control schemes are emphasized in designing power controller and voltage controller. The scheme features feed forward compensation to decouple the d- and q-axis of the Voltage Source Converter (VSC) model, which ensures the independent control of active and reactive power, DC voltage and reactive power as well. Simulations have been performed on PSCAD/EMTDC, a visual design environment for power system studies. The validity of the mathematic model and the feasibility of the control strategies have been proved by the simulation results. © 2006 IEEE.

The black start restoration of a power system after a complete blackout is a very important issue to safety of the power system. The reasonable network reconfiguration strategy is necessary for establishing the main network and restoring loads as soon as possible. A skeleton-network reconfiguration strategy is proposed in this paper. Through determining the skeleton network, the burden of network reconfiguration can be reduced effectively. The reconstructing processes are evaluated by a comprehensive index of network reconfiguration efficiency. Furthermore, discrete particle-swarm optimization is employed in reconstructing network skeleton and several relatively-optimal schemes can be obtained as the guidance of the system restoration. Application to the IEEE 30-bus power system shows that reconfiguration schemes derived from the strategy are effective under uncertain system situations and ensure that the following restoration be successful. © 2006 IEEE.

ISBN: (纸本)3952299049

A novel technique for treating electrically thin dispersive layers with the finite-difference time-domain (FDTD) method based on Z transforms is introduced. The proposed model is based on the subcell technique, where the constitutive relations are locally averaged in the FDTD grid. The most significant feature of the proposed model is its ability to model rather complicated dispersive layers having multiple pole pairs. The model is validated with several numerical examples making comparison with the exact results.

Direct torque control (DTC) has achieved utilization on two-level inverters and three-level diode-clamped inverters, and it has high performance of speed control. But DTC hasn't been utilized to cascaded multilevel inverters at present. In this paper, a novel space vector modulation (SVM) approach for cascaded multilevel inverters is presented firstly. Then by combining it with the DTC approach based on SVM, the approach of using DTC to cascaded multilevel inverters is presented. And it is verified by using a three-cell cascaded frequency control laboratory system. The proposed approach solves the issues that switching state table is difficult to generate and switching frequency is not fixed, which is arisen from using conventional DTC to cascaded multilevel inverters. It will be of benefit to the utilization of DTC on the speed control of induction motors fed by cascaded multilevel inverters. © 2006 IEEE.

With the electrical load increasing rapidly, the fault probability of power equipment is also rising greatly. This paper put forwards a new method of monitoring transformer-running state based on acoustic wave analysis. Firstly, the acoustic wave signal of the transformer running is collected by the system on chip (SOC) microcomputer. Then the signal is stored by a high-capacity secure memory (SD) card. The sound intensity and spectrum of acoustic wave is different when the power transformer running between normal and abnormal condition. Finally, the fuzzy algorithm is utilized to analyze the state of transformer. It is proved that the monitoring system based on acoustic wave analyzing can find the transformer's incipient fault on-line, and the transformer running safety and reliability can be assurance effectively.

It is a new method that monitoring the power equipments state based on image analyzing, and it can improve the automatic level of power system. Not only the video frequency would be monitored and recoded, but also the images analyzing and recognizing can be done, and it leads the incipient fault to be discovered on-line. The computer captures remote equipments images, calculates images' moment invariants as characteristic vector of recognition, recognizes power equipments by support vector machine (SVM). The system further analyzes images and find if images has convex hull, intensive stochastic noise, or false edges, sequently make a conclusion whether the running state of equipments is in order. Replace of scouting by people themselves, the use of image recognition in power system can timely find troubles and potential troubles of power equipments. So the power equipments can be inspected and maintains its working state, which would improve the running reliability of the unattended substation.

With the interconnection of power grid, the postdisturbance system is easier to suffer power-angle swing and system oscillation. Moreover, the impact of load characteristics on the system dynamic behavior becomes more obvious. Therefore a new perturbed trajectory prediction method considering load model is presented in this paper. A static load model with voltage characteristics in stead of pure impedance is introduced into the system models. The admittance matrix including load nodes and a coefficient matrix of load proportion are figured out based on the real-time data from WAMS (Widearea measurement system). Using the sensitivity equation of power flow, the linear relationship between the micro variation of electromagnetic power and that of rotor angle is deduced, and then a new perturbed trajectory prediction algorithm is proposed. Numerical simulation results on the IEEE-9 bus system show that the proposed method works well. © 2006 IEEE.
