Recent project experience and studies have shown that Type 3 wind turbine generators with power electronic converters controls operate near series compensated transmission lines are susceptible to un-damped sub-synchronous oscillations. This paper presents an overview of the Sub-Synchronous Control Interaction (SSCI) phenomenon. Simulations in PSCAD/EMTDC using a model used demonstrate SSCI, design SSCI damping controller is presented help mitigate problem. Recommendations provided...
The paper discusses the operating principles and control characteristics of a dynamic voltage restorer (DVR) that protects sensitive but unbalanced and/or distorted loads. main aim DVR is to regulate at load terminal irrespective sag/swell, distortion, or unbalance in supply voltage. In this paper, operated such fashion it does not absorb any active power during steady-state operation. Hence, DC capacitor rather than source can inverter realizing DVR. proposed operation verified through...
This paper proposes a new connection for unified power quality conditioner (UPQC) to improve the of two feeders in distribution system. A UPQC consists series voltage-source converter (VSC) and shunt VSC both joined together by common dc bus. It is demonstrated how this device connected between independent regulate bus voltage one while regulating across sensitive load other feeder. Since different (lines), will be called an interline (IUPQC). The structure, control capability IUPQC are...
The paper discusses the operation and performance of a unified power quality conditioner (UPQC). A UPQC is versatile device that can be used for various functions. main aim to operate in such way it tightly regulates bus voltage critical loads against unbalance, harmonics, sag/swell other disturbances occurring distribution system. compared dynamic restorer (DVR). Both DVR are operated closed-loop state feedback switching control. Through simulation studies using PSCAD/EMTDC shown performs...
This paper presents an inverter control strategy using output feedback control. The controller is designed in discrete-time a pole shifting law the polynomial domain that radially shifts open-loop system poles towards origin. type of very useful for custom power applications which inverters have to inject unbalanced and/or harmonic voltage or current both neutralizing imbalance harmonics. proposed design tested on three different compensating devices: Distribution Static Compensator...
Domain-specific SoCs (DSSoCs) are an attractive solution for domains with extremely stringent power, performance, and area constraints. However, DSSoCs suffer from two fundamental complexities. On the one hand, their many specialized hardware blocks result in complex systems thus high development effort. other system knobs expand complexity of design space, making search optimal difficult. Thus to reach prevalence, taming such complexities is necessary. To address these challenges, this...
