The power frequency over-voltage of EHV power transmission lines in three operating conditions, i.e., capacity effect of unloaded line, unsymmetrical faults and load shedding is analyzed. The shunt reactor's function to restrain the power frequency over-voltage is analyzed theoretically. Different compensation ratios and installment positions of shunt reactors are simulated in three operating conditions of 750 kV transmission lines through the software ATP/EMTP. From the simulation results, it is found that the shunt reactors can restrain the power frequency over-voltage in three operating condition effectively and the magnitude of the power frequency over-voltage will be lower with the compensation ratio of the shunt reactor becoming larger. In addition, when the shunt reactor is switched at the terminal of the transmission line, its effect restraining the power frequency voltage is the best compared with other two modes of connection in unloaded line with single power supply, unsymmetrical faults and load shedding. The method of operation for the shunt reactor is also discussed in this paper. Along with the expansion of the system capacity and the line's transmitted power, the method of operation that the shunt reactor is switched off from the system needs to be considered according to the power system's operation condition.

As a series FACTS device based on Voltage Source Converter (VSC), Static Series Synchronous Compensators (SSSC) can optimize power flow and improve power system stability by controlling the line impedance rapidly. According to the three levels control structure of SSSC proposed in this paper, when SSSC middle level control operates at constant impedance mode, it has characteristic of controllable impedance as viewed from the top level. In this paper, the output of SSSC is equivalent to controllable impedance and then affine nonlinear equation of the single machine infinite bus (SMIB) power system including a SSSC can be obtained without the compound coordinate transformation approach which is proposed by other documentation and the feedback exact linearization method can be used directly to obtain the SSSC top level nonlinear controller. For avoiding solving the partial differential equation, the direct method is used to realize the exact linearization simply and conveniently. For overcome the shortcoming of low robustness of exact feedback linearization approach due to uncertainty of parameters and model of controlled system, the nonlinear PID control is used to design the SSSC top level controller. Finally the paper applies Real Time Digital Simulator (RTDS) to validate the feasibility of the proposed modeling and control approach in damping out power system oscillations. © 2008 DRPT.

This paper researches profoundly on the coordinated control of UPQC (Unified power Quality Conditioner). By analyzing the radical reasons of coupling effect between UPQC series unit and shunt unit, a simple and practical coordinated control strategy for UPQC series unit and shunt unit is proposed, i.e. by introducing corresponding voltage corrective link directly to UPQC series unit and shunt unit respectively, and by suitable mode of PWM in addition, the coupling effect between its series unit and shunt unit is eliminated fully. Therefore, the complex degree of the whole UPQC control system is simplified greatly. Combined with a power quality waveform tracking method based on H∞ control, the coordinated control between UPQC series unit and shunt unit is implemented by the proposed strategy. The experimental results indicate that the method can eliminate the steady-state phase shift and amplitude attenuation of the voltage tracking compensation of series unit and the current tracking compensation of shunt unit for UPQC. Finally, the unified power quality multi-function control of UPQC is achieved. ©2006 IEEE.

In this paper, a novel method for perturbed trajectory prediction of post-fault rotor angle is presented based on PMU (phasor measurement unit) measurements and trigonometric function curve fitting technique. A mathematical model about the relationship of post-fault rotor angle and time is derived from a speed-governing system model, which reveals that the perturbed trajectory of the post-fault rotor angle can be expressed by trigonometric functions. By curve fitting technique, a least square method to predict the perturbed trajectory using trigonometric function is proposed. Numerical simulations are conducted on IIEEE 9-bus system to test the effectiveness of this method. The proposed method can give more reasonable and more promising prediction results as compared with polynomial curve fitting technique.

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.

It is very important and necessary to calculate Total Transfer Capability (TTC) incorporating Flexible Alternate Current Transmission system (FACTS) devices in power markets and analyze impacts of FACTS on TTC. Calculating TTC incorporating with FACTS devices is an optimal problem constrained by some equalities and inequalities. This paper proposes a mathematical model for calculating TTC incorporating with FACTS devices in power markets, and detailed calculation method is also put forward. The constraints include voltage constraints, thermal stability limits, generator's capacity limits, load demand, steady-state power flow, and control parameter constraints of FACTS devices, etc. The sensitivity-based repetitive linear iterative approach is proposed to solve the proposed model. The detailed solution process is described in this paper. To realize the proposed model and calculation method, a TTC calculation software incorporating with FACTS devices is developed based on PSASP/UPI, a set of advanced application software package developed by China Electric power Research Institute. This paper proposes a new approach on combined TTC solution including FACTS and power flow calculation based on PSASP/UPI, and gives the interface program for User Programming Interface (UPI) in PSASP. The IEEE 14-bus test system is used to verify the proposed algorithm and program. Numerical results show that FACTS devices and their locations have different impacts on TTC, also prove that the proposed model and algorithm is correct and effective. © 2005 IEEE.

The faults in electric power system can not be completely avoided. When power system operates from normal state to failure or abnormal operates, its electric quantities may change significantly. Our researches indicate that the variable with the biggest coefficient in principal component usually corresponds to the fault. Therefore, utilizing real-time measurements of PMU, basing on principal components analysis technology, we have completed the fault location of electric power system. Of course, because of the complexity of different types of faults in power system, there still exists enormous problems need a close and intensive study. © 2010 IEEE.

In load model verification process, the accuracy of model and its parameters makes the actual operating conditions unable to reappear in simulation. The information deviation between measured data and verifiable simulation data makes it impossible to ensure the descriptive power of measurement- -based load model for real load characteristics. With this problem, the paper applies closed-loop verification approach to this question for the first time. The closed-loop verification approach is common in system identification study but newly used in load model comparison and validation. Two cases based on PSASP are studied in the paper. The object of this study is composite load model and the verification is carried out on a 10-generator, 39-bus New England power system. They both prove the validity of composite load model and the feasibility of this verification approach. © 2010 IEEE.

The comparison between Hilbert space based power theory and three other power theories including traditional power theory , instantaneous power theory put forward by Akagi and Fryze power theory are analyzed in this paper. Theconsistency and difference are indicated in several different aspects: physical meaning, mathematical concept and the derivation of expressions. Analyses shows that traditional power theory can be regarded as a special case of Hilbert space based power theory, in other words, Hilbert space based power theory can be regarded as the generalization of traditional power theory. Fryze power theory is in accordance with Hilbert space based power theory in single-phase nonsinusoidal system, instantaneous power theory is in accordance with Hilbert space based power theory in three- phase symmetrical system without zero-sequence component. The definition of active current in Hilbert space based power theory is different from it in instantaneous power theory in three-phase system. © 2008 IEEE.
