“…In view of the above problems, in order to meet the needs of distributed generation grid is proposed in this paper a multifunctional grid simulator, multi function AC grid simulator adopts advanced control strategy can not only were four quadrant operation, to achieve energy bidirectional flow, but also provide the three-phase voltage output and simulation such as voltage sag, voltage unbalance and so on various grid status and fault [6][7][8]. Calculation of the value of a given voltage under various faults by software programming to achieve grid control strategies of fundamental mode and harmonic mode, fundamental mode adopted based on the instantaneous voltage and current values of the double closed loop control system, harmonic mode the output voltage effective value feedback control, control system has a good effect, high stability, prototype experiment results show that this control scheme is feasible [9].…”

In order to adapt to the grid test study a high power alternating current grid simulator that can simulate the network for various status and faults is proposed. The simulator could work in four quadrant operations，so that energy generated by distributed systems could flow into grid. The fundamental voltage and harmonic voltage are controlled respectively：multiple feedback loop control scheme is applied in fundamental mode and effective value feedback control scheme is applied in harmonic mode. The DSP and FPGA platform are used for implementing the system control and the experimental results show that the performance of the simulator is good and has high stability.

“…While in regions of relatively high grid frequency (50 or 60 Hz ac lines in most of the world), carrier ratio is greatly reduced. As a result, control structure with a fast current loop inside a slow voltage loop is not effective [3]. Instead, dc voltage and ac current are controlled together by 'phase and amplitude control', also called 'indirect current control (ICC)'.…”

In the application of megawatt(MW) rated railway traction drives, as switching frequency is only several hundred hertz, the bandwidth of current loop is usually limited. Instead of instantaneous current feedback control, indirect current control (ICC) is widely used in the front-end four-quadrant converters. Suffering from the low-speed dynamic response and cross-coupling between active and reactive power, conventional indirect current control is not an ideal solution for power conversion. To realize the independent control of active and reactive power, an orthogonal phasor frame is introduced. Furthermore, in order to improve the dynamic performance of conventional ICC, a novel ac current transient-free method is proposed after detailed analyzing of the ac current responding characteristic. Simulation and experiment results proved this method to be effective.

This paper presents a stability analysis of train converters in order to evaluate how the controller parameters affect the absorbed current. The new dynamic model presented in this paper is capable of considering the time-variant nature of the system for the correct tuning of the feedback proportional-integral PI controller, applying a current controlled modulation technique never used in high-power traction converters. The reduction of the harmonic content of the current absorbed by a converter employed at the input stage onboard high-speed trains is really important, considering the interaction with the signaling system set up for traffic control. A computer model of the converter, considering both the power and the control structure, has also been implemented in order to deliver a validated tool for the developed theoretical analysis.
