Wind energy has drawn worldwide attention. Because of simple structure, high efficiency, stable operation and other inherent advantages, variable speed constant frequency (VSCF) direct-drive wind power generation system using permanent magnetic synchronous generator(PMSG) is the development trend and one of the focuses of wind power generation system, on which this paper researches through its converter's topological. To be the interface between PMSG and the grid, typical converter topology structure of direct-driven wind power system with PMSG are analyzed, including the diode rectifier + DC to DC converter + inverter, and the back to back double PWM converter. The topological characteristics and applications of some high-voltage, high-power converters are introduced in detail, including Diode-clamped multi-level converter, Cascaded H-bridge multilevel converter and Flyingcapacitor multilevel converter. Their implementations, working principles, advantages and disadvantages are discussed and compared. Judging from the current situation, for the advantages of low-cost and simple control strategy, diodeclamped three-level PWM converter is the hot spot of current converting technique study for direct-driven wind power system.

作者： Xiao-yu Zheng Ren-mu He Jin Ma Key Laboratory of Power System Protection and Dynamic Security Monitoring and Control under Ministry of Education North China Electric Power University Beijing China

Load model has great impacts on the power system simulation results, while in transient stability analysis the traditional load models have some disadvantages which can't describe the load shedding characteristic when low voltage disturbances happened. Thus, a new load model is proposed in this paper after the investigation of the field measurement data and the load characteristics of some equipment under low voltage. Several new parameters describing the load shedding characteristic are provided in the new load model which can be derived by identifying the field data. With these new parameters, the load difference caused by the load shedding during the low voltage disturbances can be well illustrated. The improved load model has larger application ranges and better properties in describing the nature of the load dynamic behaviors during the transient stability analysis which also improves the reliability of the simulation. The field measurement data illustrate its efficiency.

A novel wide-area fault location algorithm is proposed in this paper. Fault model is developed in super-imposed network, and then based on network correlation coefficient matrix (NCCM), location function is defined. Finally search technique with adaptive step is used to locate fault branch and fault distance. This method requires few PMUs, avoids modifying node admittance matrix and NCCM. It has less calculation burden, and is easy to achieve. Simulation results based-on PSCAD show that the algorithm can locate fault branch accurately and fault distance precisely in condition of limited measurement points. And fault location results are not affected by fault type or fault resistance.

The paper describes the use of multi-terminal HVDC transmission system based on voltage source converter (VSC) (VSC-MTDC) for connecting doubly fed induction generator (DFIG) based wind farms over long distance. The operation principles between DFIG and VSC-MTDC of the proposed system are described. Stator flux oriented vector control technology is used to execute AC excitation for DFIG rotor, then independent control of active and reactive power is realized and electricity generation by capturing maximal wind energy is also obtained. The control objective of rectifiers is delivering the generated power from the wind farms to the DC network instantaneously and to keep AC voltage at wind farm bus constant. The control objective of inverters is receiving the power from the DC network and to keep DC voltage constant, and the multi VSCs are controlled coordinately, the relevant mathematical model was established. The parameters optimization based on simplex algorithm and objective function are used to get suitable PI control parameters of VSC-MTDC. Interactions between DFIG and VSC-MTDC link are investigated and simulations performed in PSCAD/EMTDC to verify the proposed control strategy.

Characteristic of HSC on Damping SSR

作者： Benfeng Gao Chengyong Zhao Xiangning Xiao Yang Zhao Control Ministry of Education Key Laboratory of Power System Protection and Dynamic Security Monitoring Beijing China Beijing Electric Power Corporation Beijing China

In this paper, a static synchronous series compensator (SSSC) combined with a fixed capacitor, which is called hybrid series compensation (HSC), is proposed to avoid subsynchronous oscillation (SSO) in a series compensated transmission system and its characteristic is studied based on IEEE first benchmark model for SSO analysis. By employing the complex torque coefficient method and time-domain simulation, the performance of HSC on damping SSO is analyzed in the aspects of component proportion of HSC, installation location and control strategy mode. A supplementary sub-synchronous damping controller (SSDC) for SSSC is also designed to increase the damping performance of HSC at critical oscillation frequency.

To avoid the mal-operation of transformer differential protection when external fault occurs with current transformer (CT) saturation, a new algorithm based on the mathematical morphology is put forward in this paper. Unlike the conventional Time Differential Method, the new algorithm only needs detecting the instant of fault occurring, while the instant of differential current appearance is no more needed. A new current waveform is obtained by a symmetrical transformation of initial part of differential current after fault occurrence, and then its characteristic is exacted by morphological gradient. In the case of CT serious saturation, a discrimination of external fault and internal fault can be clearly made by this algorithm. In addition, analysis shows that the new algorithm based on the mathematical morphology could also be applied for the identification of transferring fault (external fault transfers to internal fault). Simulation results of MATLAB validate its feasibility and reliability.

A three-phase unbalanced system will reduce mechanical and electrical energy interaction and thus, to some extent, inhibit subsynchronous resonance (SSR). Based on this principle, a compensation method using a single-phase static synchronous series compensator (SSSC) is proposed. In this method, only one phase employs an SSSC to replace part of the fixed series capacitor, while the other two phases have fixed series compensation (FSC). By controlling the SSSC, the three-phase reactance at power frequency is balanced, while at sub-synchronous frequencies, the system is unbalanced and thus inhibits SSO. A single-phase SSSC model based on a cascaded H bridge topology is built for time-domain simulations. The damping effect and the minimum degree of compensation required from the SSSC are analyzed by transient simulations. Simulation results show the method can effectively restrain SSO and has little effect on the three-phase voltage unbalance factor. Compared with employing SSSC in all three phases, this method is more economical.

The topology characteristics of the nodal matrix in power system analysis and the adjacent matrix in graph respectively has been proved to be absolutely identical. According to this feature and modification principles of the nodal impedance matrix, a new tracking algorithm for the state change of the circuit breaker has been built based on the general multiplication and general addition operations. The new algorithm is able to reduce the computation burden than the traditional way. Finally, the text example has validated the efficiency of the novel tracking algorithm in substation configuration.

With the increasing expansion of AC/DC transmission system scale, the research on Available Transfer Capability (ATC) for AC/DC transmission systems has important academic and practical significances to AC/DC transmission system planning, operation and reliability evaluation. Most of the existing ATC calculation methods are mainly based on deterministic techniques and suitable for AC transmission system. In practical power systems, there are large amount of uncertainties which can effect the operation of AC/DC transmission system, and power system is dynamic and time-varying. A novel approach is proposed to analyze relevant features of ATC and calculate ATC based on sequential Monte Carlo-Frequency and Duration (FD) considering uncertainties and time variation of AC/DC transmission systems. The algorithm MATLAB6.5 is developed. Modified IEEE-14 node test system is used to verify the presented approach.
