Analysis of STATCOM Controlled PMSGBased on Shore Wind Farm and Off ShoreWind Farm for Dynamic StabilityImprovement

[摘要] This paper deals with the development of a Mat lab-simulink model of a new proposed scheme for grid connected off shore wind farm (OWF) and marine current farm (MCF) on a static synchronous compensator (STATCOM). The purpose of this simulation Model to getting better damping enhancement and voltage control. An equivalent Doubly fed Induction Generator is used here to operate the Off shore wind farm while an equivalent Permanent magnet Synchronous Generator is used to operate the marine current farm. The PMSG is used to guide for an equivalent marine current turbine and the DFIG is used to guide for an equivalent Wind turbine. To design a damping controller for this proposed scheme model control theory is used here for getting the effective characteristics. The STATCOM controller plays an important role here. A frequency-domain approach based on a linearized system model using Eigen value techniques and a time-domain scheme based on a nonlinear system model subject to various disturbances are both employed to simulate the effectiveness of the proposed control scheme. It can be concluded from the simulated results that the proposed STATCOM joined with the designed damping controller is very effective to Balance the studied system under disturbance conditions. The proposed scheme of this AC bus system can easily control the voltage fluctuations.
